[00:24] <BinarySavior> Hi for setting up a service on a subdomain that exists on a separate server from the host that serves the root domain, I am required to use CORS
[00:24] <BinarySavior> according to these docs, i need to set the access-control-allow-origin header to *
[00:24] <BinarySavior> doesn't that pose security concerns? is there a better way to do this?
[00:24] <BinarySavior> https://github.com/SourceRT/dock-matrix/blob/master/docs/configuring-well-known.md
[00:26] <mason> BinarySavior: That's potentially better-asked in #ubuntu-server.
[00:26] <mason> I'm not familiar with CORS myself.
[00:27] <leftyfb> BinarySavior: just point the subdomain to the ip of the separate server
[00:28] <oerheks> there *are* concerns.. https://www.pivotpointsecurity.com/blog/cross-origin-resource-sharing-security/
[00:31] <BinarySavior> leftyfb, i did that, the service is matrix and it requires the root domain to verify with a .well-known json
[00:33] <leftyfb> BinarySavior: Sorry, I'm not familiar with either of those scenarios. Regardless, your question isn't really related to ubuntu and is a general technology/service/design question
[00:37] <Sven_vB> hi :)
[00:37] <Sven_vB> Seems like lots of cheap USB ethernet adapters are "Kontron DM9601 USB Ethernet Adapter" under the hood, and they all have MAC 00:e0:4c:53:44:58 albeit I sourced them from different vendors. I found a tutorial on how to deal with them on https://karser.dev/same-mac-kontron-dm9601/ ; maybe we should include a fix in Ubuntu by default, what do you think?
[00:37] <octav1a> yerf
[00:42] <Eickmeyer> Sven_vB: Seems as though that requires knowing the MAC address for each one, so that's not something that can be done with a blanket setting. I was going to tell you to file a bug report, but it's too device-specific.
[00:43] <Eickmeyer> Oh wait, they share the same mac address.
[00:43] <Eickmeyer> That's a security nightmare either way.
[00:44] <Sven_vB> what do you mean by security nightmare?
[00:44] <Eickmeyer> Two identical mac addresses on the same network is a no-no.
[00:45] <Sven_vB> yes, even more it's a routing problem with my hub apparently
[00:45] <Eickmeyer> Exactly. It's asking for packet collisions and misrouting.
[00:45] <Sven_vB> the tutorial assigns new MACs based on USB path, I'll probably randomize the last 3 bytes so it works even if the USB numbers happen to match up accross hosts
[00:45] <semitones> i made the mistake of thinking i had more disk space than I had, and now I have to clear a bunch of stuff to finish apt upgrading
[00:46] <semitones> is it safe to delete /var/log/journal contents?
[00:46] <Eickmeyer> Sven_vB: Either way, that's not something that can be done by default in Ubuntu.
[00:47] <Sven_vB> Eickmeyer, an official fix would probably need its own legitimately registered MAC pool to pull from. is that the obstacle?
[00:47] <Ravage> semitones: try to edit /etc/systemd/journald.conf and set SystemMaxUse=100M or so
[00:47] <Eickmeyer> Sven_vB: Yes, very much so.
[00:47] <Ravage> and restart the service
[00:47] <semitones> the 3 big places I could delete are: /var/log/journal, the old kernels, and /var/cache/apt/archives
[00:47] <Ravage> that will clean up the logs ins a safe way
[00:47] <semitones> thanks for the advice
[00:47] <Eickmeyer> Sven_vB: I'd recommend talking about this sort of thing in #networking . They'd have more insight.
[00:47] <Ravage> and /var/cache/apt/archives is safe to clean
[00:48] <Sven_vB> Eickmeyer, OTOH, there are privacy options to randomize MAC in WiFi. can't we use that?
[00:49] <Sven_vB> good idea, maybe I'll do that another time. for now I'm ok with my rogue hack I guess.
[00:49] <webchat76> hello I am a seedbox operator, 18.04.6-desktop-amd64's torrent is reporting that the tracker is blocking the requested download . I still see it as the latest torrent to seed via https://ubuntu.com/download/alternative-downloads . issues at the tracker or is a release pending?
[00:49] <semitones> Ravage, what is the service called? I tried journal and journald
[00:50] <Ravage> systemd-journald
[00:50] <semitones> thanks!
[00:50] <Eickmeyer> Sven_vB: FYI, Wifi MAC randomizations are part of the spec. Wired ethernet typically has the MAC address hard-coded in the firmware of the interface.
[00:51] <Sven_vB> oh I see. thanks for that hint.
[00:51] <Eickmeyer> webchat76: Are you talking about the mini.iso?
[00:52] <Ravage> i think he is talking about https://releases.ubuntu.com/18.04/ubuntu-18.04.6-desktop-amd64.iso.torrent
[00:52] <Eickmeyer> webchat76: Nvm.
[00:52] <semitones> Can I remove the lib/modules/oldkernel/drivers folder before doing sudo apt --fix-broken-install
[00:52] <webchat76> Eickmeyer ubuntu-18.04.6-desktop-amd64.iso
[00:52] <semitones> or will that cause problems too
[00:52] <Eickmeyer> webchat76: The link is there for me. Try refreshing your torrent with the .torrent file provided.
[00:52] <spammy> every once in a while my desktop on Ubuntu 20.04 LTS malfunctions and when I login it acts like I'm logging in and then I'm back to a login screen again. What are some troubleshooting steps I can take here?
[00:53] <webchat76> Eickmeyer I pulled the latest torrent file via https://releases.ubuntu.com/18.04/ubuntu-18.04.6-desktop-amd64.iso.torrent and my client accepted it, but no change in trackers
[00:53] <Eickmeyer> webchat76: Your main source of truth is here: http://releases.ubuntu.com/18.04/
[00:54] <Eickmeyer> webchat76: Otherwise, I'm afraid nobody in here is going to have an answer to your questions as nobody in here maintains those.
[00:54] <webchat76> Nobody here maintains https://torrent.ubuntu.com/announce ? can you point me in the direction of who may it looks like an issue at the tracker
[00:54] <Eickmeyer> Nope, that's not done here. That's done by Canonical, and they're all off for the weekend. Sorry.
[00:54] <webchat76> ooooo
[00:55] <webchat76> Eickmeyer understandable, it's probably transient. I will report back monday if the tracker is still down. the issue is anyone pulling that torrent wont get the file. Other Ubuntu torrents are reporting to tracker A OK. I am always seeding out ubuntu stuff
[00:55] <Eickmeyer> This chat is manned by volunteers, webchat76.
[00:55] <webchat76> @eck
[00:55] <webchat76> whoops
[00:55] <webchat76> Eickmeyer I totally understand, was starting here to figure out who / where I might need to report it
[00:55] <semitones> thanks for seeding webchat76 :)
[00:56] <Eickmeyer> Volunteers aren't going to have access to the infrastructure, webchat76.
[00:56] <Eickmeyer> It'll probably resolve itself by Monday, webchat76.
[00:56] <webchat76> Eickmeyer makes sense. Like I said I figured I'd start in IRC tho
[00:56] <webchat76> I agree
[00:57] <webchat76> anyway thanks for the help. I'll keep an eye on it and hope it just bounces back
[00:58] <leftyfb> semitones: using rm on system files and directories is usually never the correct answer
[00:59] <leftyfb> semitones: once you resolve your issue you should reinstall the kernels you manually deleted and remove them properly with apt
[00:59] <leftyfb> semitones: how big of a partition are we talking about ?
[00:59] <semitones> i know :/ but I cannot apt autoremove. I did -fix-broken, and hopefully there is enough disk space to complete that now that the journals are mostly deleted. Then I can remove the kernels. I can't remove them now because apt is broken
[00:59] <semitones> leftyfb, 11 GB
[00:59] <semitones> well
[01:00] <semitones> 10.9 :/
[01:00] <leftyfb> That should be plenty of space. You filled it up with other things
[01:01] <semitones> this is with ubuntu studio but honestly I should figure out how to uninstall those programs because it is not safe having it this full
[01:01] <leftyfb> semitones: you should after removing kernels and shrinking your journal you should have enough space to remove packages one at a time
[01:01] <semitones> i didn't have to rm the kernels, glad I didn't have to
[01:01] <leftyfb> semitones: can you install and use ncdu?
[01:02] <semitones> hold on, apt autoremoving
[01:02] <semitones> ok now I have 1.5 G available. looking up ncdu
[01:03] <semitones> it is already installed but idk how to use it
[01:03] <Ravage> sudo ncdu -x /
[01:04] <leftyfb> that should tell you where most of your space is being taken up
[01:04] <leftyfb> I’m guessing most of it is in your home
[01:05] <semitones> i'm in a file browser in the terminal. THere is a gui that does this
[01:05] <semitones> i have 5.8 GB in usr 2.6 in lib, 1.3 in var, and the rest is less
[01:06] <Ravage> yes ubuntu comes with a gui tool for that
[01:06] <semitones> 216 mb in home
[01:06] <Ravage> i still prefer the terminal
[01:07] <semitones> in ncdu i'm stuck in the home folder i guess i forgot to type the /
[01:07] <Ravage> maybe ubuntu studio just comes with a lot of stuff
[01:07] <Ravage> i never used it
[01:07] <semitones> ok i got it now
[01:07] <semitones> yeah I guess so
[01:08] <semitones> if you're curious Ravage here is the output https://paste.ubuntu.com/
[01:08] <semitones> uh
[01:08] <semitones> https://paste.ubuntu.com/p/WTsKrkd4HG/
[01:09] <Ravage> you can check the subfolders but i dont think you will find a lot you can just delete
[01:09] <Eickmeyer> semitones: Ubuntu Studio leader here. What are you trying to remove? Non-audio stuff?
[01:11] <leftyfb> semitones: drill down to /usr my guess is you have multiple kernels and their related files installed and should work on cleaning up older kernels
[01:11] <leftyfb> Also, running Ubuntu studio on only 11gb?
[01:11] <Eickmeyer> Ooof, yeah, that's way too small for Studio.
[01:11] <semitones> yeah, now I know. I think i installed it in 2016
[01:12] <semitones> I ended up not using any of the studio things on this device
[01:12] <leftyfb> semitones: ah, so you’re running an EOL release and need to upgrade anyway
[01:12] <semitones> i'm upgraded
[01:12] <Eickmeyer> leftyfb: Don't be so quick to assume. ;)
[01:12] <leftyfb> semitones: not if you installed it in 2016
[01:12] <semitones> it was tricky but this channel helped upgrade to 20.04 awhile ago, and i had barely enough space
[01:12] <semitones> I had to remove all the snap stuff and some other things
[01:12] <leftyfb> ugh
[01:13] <leftyfb> All this work for an 11g install
[01:13] <semitones> it is on a microsoft surface so I'm not confident I can get it working if I reinstall :/
[01:13] <semitones> it was a headache with all the uefi and secure boot and custom kernel
[01:13]  * leftyfb taps out
[01:13] <semitones> that's probably smart, i'll just look around in synaptic and remove things
[01:15] <Eickmeyer> semitones: Another thing that might help is if you go through each of the ubuntustudio-* metapackages and find their dependencies/recommends and remove each one one-by-one via synaptic.
[01:15] <Eickmeyer> semitones: For instance, ubuntustudio-graphics: https://packages.ubuntu.com/focal/ubuntustudio-graphics
[01:16] <semitones> thanks, I'll start there
[01:16] <Eickmeyer> semitones: I wish it were as simple as, for example, "sudo apt autoremove ubuntustudio-graphics" but it wasn't installed via a metapackage but rather the germinate seed.
[01:17] <Eickmeyer> In the future, I might make a script that removes stuff based on the contents of the metapackages, but for now, this is what we've got. :)
[01:17] <semitones> I appreciate the support, this is definitely a good way out of this problem of my own making :)
[01:18] <Eickmeyer> semitones: And I'd seriously consider repartitioning that drive to get more than 11GB. :)
[01:18] <sarnold> oof, 11gb filesystem? that'll be tight..
[01:18] <semitones> I'll see what I can do
[01:19] <Eickmeyer> sarnold: Especially for Studio. ;)
[01:19] <sarnold> if you can install anything :) then the orphaner tool may help
[01:19] <semitones> checking it out
[01:19] <sarnold> if you've got any snaps installed on that filesystem, it might be worth trying to figure out how to keep fewer snaps installed, too
[01:20] <sarnold> snapd by default keeps two or three copies of everything so it can roll back bad updates
[01:25] <semitones> i think we removed all the snaps last time
[01:28] <sarnold> hah
[01:30] <semitones> Eickmeyer, removing the papirus icons is helping
[01:33] <leftyfb> I can’t imagine icons take up much space
[01:35] <semitones> 200+ mb
[01:35] <semitones> i found a good one: remove the fluid synth, and it removes a lot of things
[01:36] <semitones> i don't really need libreoffice
[01:38] <semitones> i'm making progress, but the biggest area I don't understand is 1.3 GB: /usr/lib/x86_64-linux-gnu
[01:40] <leftyfb> Those are files related to your kernel(s)
[01:40] <leftyfb> DO NOT delete those with rm
[01:41] <sarnold> yeah don't delete those manually; purge packages you don't use, if you want to clean that up a bit, but do *not* treat that directory as one big homogenous entity
[01:41] <leftyfb> semitones: drill down, are there more than 1 kernel directories ?
[01:42] <sarnold> (btw those are libraries, not kernels)
[01:42] <semitones> good advice let me look what has remained
[01:42] <leftyfb> You can purge kernels you aren’t using, but if there’s only 1 kernel, I wouldn’t touch anything in that directory
[01:42] <semitones> i kept 2 kernels for posterity, but removed the lowlatency kernels
[01:42] <leftyfb> sarnold: I said files related to the kernels
[01:44] <semitones> nothing relating to the kernels stands out. I think I can probably remove JACK though
[01:45] <semitones> that also removes a LOT of packages
[01:46] <semitones> leftyfb, what files would I be looking for? I don't see much about the kernels in /usr/lib/x86_64-linux-gnu
[01:46] <leftyfb> semitones: from what I understand, studio uses Jack for sound as opposed to pulse audio. If you don’t have pulse installed, removing Jack will remove your sound capabilities
[01:47] <semitones> can i just apt install pulseaudio
[01:48] <leftyfb> You can, but over never known pulse to be that easy to get running from a system that didn’t have it already
[01:48] <semitones> hmm maybe I will leave jack alone for the time being
[01:50] <semitones> can I uninstall gcc? I don't have an nvidia gfx card, so I don't think I need to compile any dkms modules
[01:52] <sarnold> yeah, probably; most people don't need it; be sure to keep going, delete eg gcc-10 or gcc-9 or whatever other packages you've got installed; maybe you've got some -dev packages installed that don't need, too; dpkg -l '*-dev' | grep '^ii'  might be useful, too
[01:52] <semitones> if I removed libreoffice already, can i delete /var/lib/x86_64-linux-gnu/libreoffice
[01:52] <semitones> that's a good idea with the -dev
[01:52] <semitones> i've started sorting by "installed" with synaptic
[01:52] <sarnold> try dpkg -S /var/lib/x86_64-linux-gnu/libreoffice   -- that might show packages that own files there
[01:54] <semitones> there are some things that depend on some of gcc that seem important, like acpi stuff
[01:54] <sarnold> hmm
[01:54] <sarnold> pastebin what you see?
[01:54] <semitones> sure
[01:55] <semitones> specifically gcc-10-base
[01:56] <Eickmeyer> leftyfb: That's false, it uses Pulseaudio by default, and Jack on demand using Studio Controls to do the configuring.
[01:56] <Eickmeyer> semitones: ^
[01:56] <semitones> so it is ok to remove jack?
[01:57] <Eickmeyer> semitones: If you don't do professional audio work, sure. But it's so small it's negligible.
[01:57] <Eickmeyer> Wouldn't help your cause.
[01:57] <semitones> Eickmeyer, ok
[01:57]  * Eickmeyer is out for the evening
[01:58] <sarnold> semitones: probably best to leave gcc-10-base alone -- it looks like it owns just a few files and none of them are large, but it's a dependency on something that looks like it ought to stick around
[01:59] <semitones> thanks :)
[01:59] <semitones> ok, yeah, it's doing different things in apt than it was in synaptic, but none of them good so I'll leave it alone
[02:05] <semitones> someday I'm going to need to give ubuntu studio a disk all to itself
[02:05] <semitones> and buy a usb-interface
[02:09] <semitones> I think i have removed almost as much as possible this time; I have about 4.1 GB available, according to df -h
[02:09] <sarnold> nice
[02:09] <sarnold> now bust out orphaner
[02:09] <leftyfb> Eickmeyer: sorry about that. I did preface with “from what I understand”. I understood wrong
[02:11] <semitones> oh this is great
[02:15] <semitones> whew ok now I will reboot and see if I still have a system
[02:16] <sarnold> good luck :)
[02:17] <semitones> what have i done
[02:17] <semitones> i miss ubuntu-studio already; everything is high-dpi small now, and looks like xfce
[02:17] <sarnold> d'oh :)
[02:17] <sarnold> too many changes in one go
[02:18] <semitones> ok fixed some of the scaling maybe
[02:18] <relipse> I am coding a 2D rpg puzzle game anyone want to see it?
[02:22] <leftyfb> !ot | relipse
[02:23] <semitones> maybe i can install ubuntu-studio again
[02:25] <leftyfb> semitones: if you’re not working with audio, why would you? You just spent all this time and effort deleting it to free up space
[02:25] <semitones> because everything on my screen is small
[02:25] <semitones> and I don't have the unity dock thing anymore
[02:26] <semitones> it is 330 mb to install it again
[02:35] <semitones> Ok
[02:36] <semitones> Something I did messed up update-grub and I don't have any Ubuntu boot options any more
[02:36] <semitones> So I'm researching how to boot without a boot entry, but maybe at this point it's best to call it a night
[02:36] <sarnold> ouch :/
[02:37] <sarnold> there's handy logs in /var/log/apt/ and /var/log/dkpg.log -- the dpkg ones are way harder to read but cover more operations
[02:37] <sarnold> they may help you figure out what was too important to delete
[02:39] <leftyfb> I’m guessing some kernel or initrd got deleted
[02:40] <semitones> something pulled in ubuntustudio-lowlatency-settings
[02:40] <semitones> that broke update grub, and I thouught i fixed it by rm /etc/grub.d/09_lowlatency
[02:41] <semitones> but when i ran update-grub again it 'succeeded' but i didn't realize it didn't find any ubuntu kernels...
[02:57] <semitones> can't remember the name of my root partition it is one of those /dev/nm020x things not a sensible one
[02:59] <semitones> but! luckily i have a boot entry that doesn't work any more, but it DOES have the uuid string for the correct partition
[02:59] <semitones> so I just have to copy it letter by letter
[03:00] <semitones> do uuids tab-complete?
[03:03] <MinusOne> semitones, tab completion is contextual. The easiest way to find out is by pressing tab. And you could copy/paste
[03:04] <semitones> i don't know how to copy/paste in grub
[03:08] <semitones> WHOOHOO i'm in the mainframe
[03:11] <semitones> update-grub is still not pulling in any linux kernels :(
[03:14] <semitones> hmm
[03:15] <semitones> for some reason /etc/grub.d/10_linux is not marked as executable
[03:15] <semitones> chmod +x
[03:15] <semitones> phew
[03:15] <semitones> that fixed it. I am not sure what I could have done that would have messed that up
[03:17] <sarnold> wild, that's pretty unusual :)
[03:17] <semitones> never too old to hose your system
[03:17] <semitones> at least i didn't lose any data
[03:18] <sarnold> *nod* worst case is almost a best case -- your data's still there, but you could grab a new drive, do a new install with a friendlier partition scheme, and then copy data back, hehe
[03:20] <semitones> this is already a huge sidetrack from my intended project for tonight; was trying to format an sd card in windows and kept getting a bluescreen; booted into ubuntu on the same machine; it asked to upgrade, and here we are lol
[03:22] <sarnold> sheesh :) that's a heck of a lot of sidequests
[03:28] <semitones> this always happens to me
[03:29] <semitones> if I were a linux wizard i'd be a wild mage; but without the chance that something good would happen
[03:30] <jhutchins> semitones: Experience is proportional to data destroyed.
[03:30] <Guest92> (y)
[03:33] <semitones> i am a student of the tao, but fairly delinquent http://taobackup.com/
[03:41] <jhutchins> I probably have at least three dead UPS batteries on-line.
[03:43] <semitones> I have a raspberry pi with a ups; it is the safest thing in the house; and it's in charge of recording jeopardy :)
[03:43] <Comnenus> jhutchins: why keep them?
[03:43] <lotuspsychje> !ot
[03:46] <jhutchins> Comnenus: They're all in use.  At least they work as line conditioners.
[03:46] <jhutchins> Comnenus: (That's what I meant by "on-line".)
[03:47] <Comnenus> jhutchins: understood, good point.
[03:48] <jhutchins> Does Ubuntu have good tools for monitoring APC UPS batteries?
[03:50] <MinusOne> jhutchins, I have had the most luck with NUT (netowrk UPS tools), but apcupsd also exists and although it has done poorly for me, others say it is good
[03:52] <leftyfb> I’ve used apcupsd. It works but it’s antiquated
[04:12] <JoeBk> I was unable to unstall ubuntu-20.04.4
[04:12] <JoeBk> the install just hangs
[04:17] <JoeBk_> my connection dropped
[04:17] <JoeBk_> has anyone tried installing 20.04.4?  20.04.3.0 works fine.
[05:57] <guiverc> JoeBk, iso.qa.ubuntu.com says I ran 20.04.4 43 times in QA-tests; I don't recall any failures - but I don't remember any
[06:07] <JoeBk> guiverc, I was able to get 20.04.4 to install after I cleared the drive.  I don't know is there is a problem or not.
[06:07] <JoeBk> it requires further investigatio.
[06:07] <JoeBk> investigation
[06:08] <JoeBk> we'll see if anyone else complains.
[06:55] <JoeBk> guiverc, I think I found the problem.  When I have an external 6TB Western Digital MyBook conected the install hangs.
[08:04] <webchat92> My ubuntu laptop shuts down on its own sometimes and shows the dimming light on force restarting any idea?
[08:06] <JoeBk_> webchat92, Is battry run down?
[08:06] <webchat92> yes the battery is in fault actually
[08:07] <webchat92> it is slow on charging and capacity of battery has been affected somehow ... could that be causing issue
[08:07] <webchat92> on bootup also laptop shows this warning to replace battery
[08:08] <JoeBk_> It sounds like the battery is causing the problem.
[08:09] <webchat92> but what if I use the laptop without the battery, directly connecting it to the power adapter
[08:10] <webchat92> In this as well, I can see the issue
[08:13] <webchat925> yes webchat92, I also have similar problem
[08:14] <webchat925> JoeBk can you please advice
[08:51] <ashkan> Hello, I'm trying to install an encrypted Ubuntu 20 desktop on KVM. when I reboot after installating the OS I get a black screen which I can pass with blindly typing in the password a couple of time
[08:52] <ashkan> I've upgraded the OS to the latest and rebooted again but it didn't make any difference.

[10:19] <sim642> I just upgraded Xubuntu 21.04 -> 21.10 and now I cannot switch bluetooth headphones to HSP/HFP any more. Any ideas why that would be?
[11:29] <dojo> where is a reliable source to find hashes for my ubuntu desktop iso files? I have found this "https://help.ubuntu.com/community/UbuntuHashes" but i normally would head to "https://ubuntu.com/download/desktop", unfortunately i cant find any hashes in the second location (whether via link from that page or lower down the page-any suggestions)
[11:32] <dojo> https://ibb.co/Ks3GwDw
[11:32] <tomreyn> https://ubuntu.com/tutorials/how-to-verify-ubuntu#1-overview
[11:33] <dojo> i know how to do it but i'd like to know a trustworthy place to get the hashes from
[11:33] <tomreyn> why do you need that, when they are signed?
[11:34] <tomreyn> and how is https://releases.ubuntu.com/ not trustworthy?
[11:45] <dojo> can you explain that please? i wasn't aware they (iso, img from those sites were signed) and ive been having trouble getting a usb with iso flashed to it to work like normal (for a fresh install)
[11:46] <dojo> since i was having trouble gettng the usb to boot successfully i thought it'd be a good idea to check the md5sum
[11:47] <tomreyn> dojo: the iso's are not signed, but the checksum files over them are
[11:48] <dojo> i dont normally but am at the end of ideas on how to get the flashed iso to work have tried different ports and usb devices-no luck so far, only thing i can think of is the integrity of the image iso. thanks for the info
[11:49] <tomreyn> dojo: the tutorial i linked to explains how you can download SHA256SUM (checksums) and SHA256SUM.gpg (cryptographic signature over SHA256SUM) files from the release mirrors and use the gpg software to authenticate the checksum files
[11:50] <dojo> stubborn me soz =(, i will read it and thanks for your help
[11:50] <dojo> reboot time ciao for now
[11:50] <dojo> and cheers
[11:52] <tomreyn> when you *both* verify the checksum of the download and use a software such as balena etcher (as shown on the tutorial), which will verify the data was properly written to the install media (usb stick?), you should be a in a good position to make an installation. note that the installer itself does also run a self-test on some files while it boots.

[14:18] <BluesKaj> Hi folks
[14:18] <Maik> hi BluesKaj
[14:18] <BluesKaj> hi Maik
[14:36] <Guest14> Can someone help me with getting nvidia drivers working on my AMD/NVIDIA hybrid system.
[14:37] <michael> cool
[14:38] <BluesKaj> hybrid system?
[14:38] <lain9> amd igpu and 1650 on this laptop.
[14:38] <lain9> and the drivers dont work properly.
[14:39] <lain9> The additional drivers app also failed to install drivers properly.
[14:39] <lain9> "NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."
[14:40] <BluesKaj> lain9,  did you run :sudo ubuntu-drivers list" to find the correct driver
[14:41] <lain9> nvidia-driver-470, (kernel modules provided by linux-modules-nvidia-470-generic)
[14:41] <lain9> nvidia-driver-510, (kernel modules provided by linux-modules-nvidia-510-generic)
[14:41] <lain9> nvidia-driver-470-server, (kernel modules provided by linux-modules-nvidia-470-server-generic)
[14:41] <lain9> nvidia-driver-450-server, (kernel modules provided by linux-modules-nvidia-450-server-generic)
[14:41] <lain9> I tried to install 510
[15:11] <pavlushka_> gnome-todo, where it stores its todo data?
[15:12] <oerheks> gnome-todo using Evolution-Data-Server as its storage back-end.
[15:12] <oerheks> https://askubuntu.com/questions/1021405/where-does-gnome-to-do-stores-its-file-by-default
[15:14] <pavlushka_> oerheks: wow, ty
[17:38] <Guest39> do i need a swap as i am using 32GB RAM?
[17:39] <leftyfb> Guest39: no
[17:39] <Guest39> so i don't need a like a swap partition or file or anything?
[17:40] <leftyfb> Guest39: unless you're running a server where you know you'll be running some really memory-intensive application(s) and your swap space on is some reason fast SSD. In which case, you probably wouldn't be asking this question.
[17:41] <Guest39> oh no yeah i just want to browse and stuff
[17:41] <Guest39> thanks
[17:41] <leftyfb> Guest39: them 32G is overkill and years of headroom
[17:41] <Guest39> i might want to like install steam or smth
[17:42] <Guest39> should i take out some RAM or is it okay to keep it all in there?
[17:42] <leftyfb> it's ok to leave it
[17:43] <Guest39> thanks
[17:43] <ghost> I have a folder with thousands of files, is there a way to save the thumbnails generated. Everytime I open the folder it has to load the thumbnailsb
[17:45] <leftyfb> ghost: can you better describe your issue? You're asking if there is a way to save the thumbnails that are generated (yes, don't delete them) but then are complaining that "it has to load the thumbnails"
[17:48] <ghost> So, every time I open the folder the files show blank and it takes roughly 50m to generate all the thumbnails. If I close the folder and reopen it the thumbnails are gone and it starts regenerating
[17:49] <ghost> Is there a way to have the filesystem (nautilus) rember the thumbnails cache
[17:52] <leftyfb> ghost: https://davejansen.com/increase-thumbnail-cache-in-ubuntu/
[17:53] <ghost> Thank you
[18:02] <Guest75> Hello everyone, i just made a fresh ubuntu install and updated all my packages, however when i open my laptop lid the pc doesnt wakeup
[18:20] <plujon> I'm on ubuntu 20.04 and using Wayland.  I'm not sure what "window manager" I'm using.  I'd like to be able to move windows with the keyboard, like I used to do when I used OpenBox.  In particular, I want to move windows horizontally instead of having them take up half the screen when I push Super-left or Super-right.
[18:27] <lotuspsychje> plujon: for tweaking your system, try dconf-editor to find the right value for the setting you looking for
[18:30] <plujon> lotuspsychje: Thanks, um, such as, "org.gnome.desktop.wm.keybindings Move Window to right side of screen" ?
[18:31] <lotuspsychje> plujon: not sure myself, i dont use hotkeys too much
[18:31] <plujon> a.k.a. /org/gnome/desktop/wm/keybindings/move-to-side-e
[18:31] <lotuspsychje> plujon: i found a nice workspaces indicator that serves all my needs gui
[18:33] <plujon> These values look a lot like the ones in Settings > Keyboard Shortcuts
[18:33] <plujon> AFAICT, there is no option to move a window left or right without resizing it.
[18:35] <jhutchins> plujon: That would make sense if the window were full scren.
[19:11] <chipas> hello, so i was creating software raid 1: sudo mdadm --create --verbose /dev/md2 --level=1  --raid-devices=2 /dev/sdc /dev/sdd    but i forgot to add --assume-clean
[19:11] <chipas> what should i do?
[19:12] <chipas> should i just wait .. 8 hours or somehow stop the sync and rerun with --assume-clean?
[19:12] <chipas> if stop sync, how should i do it?
[19:18] <semitones> I don't know about raid
[19:18] <semitones> Do you have backups?
[19:18] <semitones> What is it doing that is taking so long
[19:22] <leftyfb> chipas: that's up to you. It's just skipping over writing 0's
[21:42] <jhutchins> Wow! More than two hours~
[21:44] <Maik> jhutchins: ?
[21:46] <jhutchins> Dead air.  Great use of resources!
[21:48] <Maik> yep, it's not what it used to be
[21:49] <Jeremy31> Must mean most problems are fixed
[21:49] <jhutchins> I wonder what could have discouraged people from using this channel?
[21:50] <Jeremy31> me?
[21:56] <GreasyHairyNewb> I am running across a privilege issue on Ubuntu 20.04 while trying to access Tripwire. Specifically this command. https://pastebin.com/MG8hGrtq
[21:57] <leftyfb> GreasyHairyNewb: how did you install tripwire?
[21:57] <GreasyHairyNewb> leftyfb sudo apt-get install tripwire
[21:58] <leftyfb> GreasyHairyNewb: ls -l /var/lib/tripwire/server-01.twd
[21:58] <GreasyHairyNewb> No such file or directory.
[21:58] <leftyfb> GreasyHairyNewb: https://computingforgeeks.com/install-and-configure-tripwire-on-ubuntu/
[21:59] <leftyfb> the instructions seem to imply that is normal and part of the process
[22:02] <GreasyHairyNewb> leftyfb I have been using the exact guide. After that part of the tutorial it tells me I can print the database as so https://pastebin.com/L5wYGUKp
[22:03] <GreasyHairyNewb> I still do not have access it seems
[22:03] <GreasyHairyNewb> Oh wait. One moment sorry
[22:04] <GreasyHairyNewb> Hmm.. Double brain fart. I am lost still.
[22:04] <enigma9o7[m]> don't literally type  /path/to/database.twd; instead you should put the path to your actual databise file
[22:05] <GreasyHairyNewb> enigma9o7[m] Oh wow.. I am such an idiot right now. Thank you...
[22:07] <GreasyHairyNewb> After fixing the newb issue. I still have privilege issues https://pastebin.com/dwW5RyQk
[22:08] <GreasyHairyNewb> enigma9o7 Any ideas?
[22:14] <syphyr> Hi, I'm running 18.04 and I just started seeing this "df: /run/user/1000/doc: Operation not permitted"
[22:16] <syphyr> I see this https://askubuntu.com/questions/1227667/df-command-throws-error-on-run-user-1000-doc-folder
[22:17] <syphyr> should I remove flatpak?
[22:17] <syphyr> the end of that thread says it was fixed in gnulib
[22:18] <syphyr> in june 2021
[22:19] <leftyfb> syphyr: pretty sure you answered your own question. It probably makes sense to upgrade to 20.04 anyway
[22:19] <MiguelX413> why doesnt focal-backports have ffmpeg?
[22:21] <enigma9o7[m]> focal-updates has it
[22:22] <enigma9o7[m]> https://packages.ubuntu.com/focal-backports/allpackages has cockpit!
[22:24] <MiguelX413> enigma9o7[m]: not as new as i need it
[22:24] <leftyfb> !latest | MiguelX413
[22:24] <MiguelX413> should i just install the impish .deb for ffmpeg for now?
[22:24] <leftyfb> That is not recommended
[22:24] <leftyfb> Did you check for a snap?
[22:25] <MiguelX413> leftyfb: i'm not looking for latest, im looking for a version that came out in mid 2020
[22:26] <MiguelX413> focal has 4.2.4, and i need 4.3.2+
[22:26] <tomreyn> there are 4.3.1 and a 4.4.1 nightly as snap
[22:27] <MiguelX413> hmmmmmmmmmmmm
[22:27] <MiguelX413> i wonder if it'd work well with my application
[22:28] <MiguelX413> tfw debian stable actually has a newer version of ffmpeg
[22:28] <enigma9o7[m]> Well that kinda makes sense doesn't it.  Ubuntu LTS was 2020-04.  Debian STable was 2021-09 I think
[22:29] <MiguelX413> that makes sense actually yeah
[22:30] <tomreyn> there are also PPAs providing newer versions for 20.04
[22:32] <MiguelX413> tomreyn: ppa:savoury1/ffmpeg4?
[22:33] <tomreyn> MiguelX413: i don't remember which ones, just noticed there are some with recent builds on a quick glance.
[22:34] <enigma9o7[m]> Also in a couple months there will be a new Ubuntu LTS which will surely have much newer stuff than the current LTS too...
