[00:29] I have a game installed that I'm trying to uninstall. Right clicking on it in the applications menu and selecting 'show details' brings up Software, but tells me there are no details available. I've tried to run apt remove with the package name, but it tells me there's no such package installed, and yet the game is certainly installed and can run [00:30] how did you install it? as a snap, perhaps? [00:30] I don't know. POssibly [00:30] 'snap list' in terminal [00:30] apt list mars* brings up both the game package and the game data package, marsshooter and marsshooter-data [00:31] sudo snap remove marsthingy [00:31] thanks, it looks like it's actually uninstalling this time [00:31] oke, have fun! [00:33] also fwiw it might still be best practice but with the snap command it still asks for sudo password [00:33] so you only have to do snap remove [00:36] No, still asks password. [00:36] It still asks password but you don't have to preface with sudo [00:37] but after 1 sudo comand, the environment stays open for a few minutes, so next sudo does not ask it. [00:37] oh, i get your point [00:37] yes, indeed. [01:40] Ubuntu LTS live media can do ZFS, but last time I looked they're ZFS 0.8 [01:40] ZFS 2.0 introduces Zstd support, which is Super Nice. Do/will 20.04 media support ZFS 2? [01:41] (Or would I have to grab 21.04 or something) [01:51] twb: OpenZFS 2.0.0 (which i' *guessing* you're referring to) only released 20 days ago. the latest ubuntu release is 20.10, which, as the version name indicates, released in october. [01:51] !latest [01:51] Packages in Ubuntu may not be the latest. Ubuntu aims for stability, so "latest" may not be a good idea. Post-release updates are only considered if they are fixes for security vulnerabilities, high impact bug fixes, or unintrusive bug fixes with substantial benefit. See also !backports, !sru, and !ppa. [01:53] Yeah understood. I guess I thought Canonical might make an exception :-) [01:54] !ubuntu+1 [01:54] Hirsute Hippo is the codename for Ubuntu 21.04. For technical support, see #ubuntu+1. For testing and QA feedback and help, see #ubuntu-quality. [01:54] but so far, hirsuite has 0.8.4 [01:55] there could be a !ppa or other third party repository, or a snap [01:55] likewise in Debian (see rmadison) [01:55] just did :) [01:56] But Canonical's doing legally dubious stuff with zfs drivers so I *assume* they're not just pulling zfs-dkms from debian [01:56] !discuss [01:56] Want to talk about Ubuntu, but don't have a support question? /join #ubuntu-discuss for non-support Ubuntu discussion, or try #ubuntu-offtopic for general chat. Thanks! [02:08] Why can't I put underscore in hostname?? [02:11] Deyaa: on ubuntu, or on debian, or on something else? [02:13] because it doesnt follow the fqdn spec [02:13] Valid characters for hostnames are ASCII from a to z, the digits from 0 to 9, and the hyphen (-). A hostname may not start with a hyphen. [02:15] tomreyn: Debian [02:17] hello guys [02:17] kk4ewt: oerheks it's a little bit strange that android phones support putting underscores in hostname? I thought it's normal. [02:18] I'm having some headaches with usb drives. [02:18] Crazy stuff.

While you wait, try searching https://help.ubuntu.com or https://ubuntuforums.org or https://askubuntu.com/ [02:25] the USB drive is actually 8GB [02:25] usb_destroyer: what is the actual fault? [02:25] for some reason gdisk and fdisk only see that after I zeroed the first sectors, because it was only seeing 4GB [02:26] twb, I cannot use GParted or other gdisk, or fdisk, because of this. [02:26] usb_destroyer: is it a "name brand" USB key, or a 10 RMB one from a street vendor? [02:26] 8GB kingston [02:26] usb_destroyer: does this fault affect all your USB keys, or only a specific subset? [02:27] well, I have another kingston usb drive, but it is more damaged [02:27] usb_destroyer: does the fault appear reliably on all USB ports / computers? [02:27] yes [02:28] the funny thing is, I can format it on a FreeBSD system, and it works on ubuntu! [02:28] usb_destroyer: it sounds to me like the FTL is irreperably damaged on that specific key, and it should just be thrown away. If you can't afford that, try using blkdiscard and/or wipefs to try to reset the parts you can reset. [02:28] But gdisk, fdisk, gparted, all of them see it wrong. [02:29] I used wipefs, and it removed the EFI partition and a FreeBSD label that were left there for some reason. [02:29] that was nice but didn't solve the problem [02:30] What blows my mind is that Nemo sees the USB drive as it is: 8GB with a FAT32 partition. [02:30] but gdisk, fdisk, and gparted struggle to see anything real [02:30] Deyaa: surprisingly, #ubuntu is not for debian support === semeion is now known as mnemonic [02:34] So how is it possible that I can plug this USB drive and write and read from it, and the file explorer sees it as it is, with a MBR and FAT32 partition and all... but partition tools see what I posted? [02:34] they were previously seeing 4GB, then I zeroed up to sector 32. [02:35] Then they see what I posted. [02:35] now they see that. [02:35] http://0x0.st/iCAg.txt === zbenjamin_ is now known as zbenjamin === de-facto_ is now known as de-facto [02:38] usb_destroyer: a replacement 8G key is $5; we've already wasted more man-hours than that. This isn't worth discussing further. [02:39] twb, my salary is literally zero, twb, thank very much for your advice [02:40] I'm glad to know that you got a job, I don't. [02:40] I don't have one. [02:40] $5 is food for one week to me. [02:41] ubuntu does not fix broken usb drives. [02:41] oerheks, fdisk and gdisk are for what then? === wodencafe is now known as wodenchristmas [03:02] trying to find the correct way to set my DNS server on ubuntu server 20.04. should i be using netplan? my /etc/netplan dir is empty which contradicts all the tutorials i can find :/ [03:19] Even more interesting, I just did a `dd if=/dev/zero of=/dev/sdb bs=16MB` and guess what... it runs out of space at 4GB, but the file explorer still mounts and sees the FAT32 partition and its files in it! [03:19] wtf! [03:19] and the 8GB free space too! [03:24] Sounds like your file manager (or udisks2) is broken [03:24] Note that you can simply do "cp /dev/zero /dev/disk/by-id/usb-KINGSTON-aaaaaaa" instead of fine-tuning block sizes with dd [03:26] hmmm, haven't thought of that, twb , thanks [03:30] file manager works, I can write files, copy, delete... everything works fine. [03:31] dd, gdisk, fdisk, gparted... they all see 4GB max [03:35] besides, they error out when trying to format or anything [03:35] but file manager works just fine, on 8GB, FAT32, normal [04:54] ok, look at this: http://0x0.st/iCmT.txt [04:54] However gparted, dd, gdisk, fdisk, they only see half of the size [04:57] my touchpad taps are not working on new ubuntu 20 installation. what should I do? [04:58] Size: 7743995904 [04:58] friv: upgraded from some older version of Ubuntu where it worked? [04:58] matsaman, yup, actually it was working previously in ubuntu 20 as well [04:59] friv: use "xinput" CLI tool to debug maybe [04:59] friv: previous to what? [04:59] twb, it shows the touchpad listed yes [04:59] matsaman, previous to the current installation [05:01] friv: oh you had 20 and then reinstalled it for some reason? [05:01] friv: was the old version from an upgrade or was freshly 20? [05:02] both were freshly installed [05:02] i need to relog 1 se [05:02] 1sec* [05:03] hello, when I try to copy files from my local computer to a remote server, mc says "operation not permitted". how can I fix this? [05:04] after relog they are working [05:04] solved I guess [05:04] thanks [05:05] friv: hrmm [05:05] friv: sometimes if you have the wrong thing on your touchpad [05:06] like some oil or fluid or it just booted up with something interfering with it, it can be confused for the duration of the session [05:06] cloudcell: using mc as an ftp client, you mean? [05:06] yes matsaman [05:06] interesting [05:07] pretty unavoidable potential problem with _touch_ pads [05:07] (that is, modern touchpads that support gestures and don't need to actually be depressed) [05:08] ok [05:14] can anybody help? matsaman ? === keiser5 is now known as keiser [05:30] ok, this is weird [05:30] I used gnome disk utility and tried to restore a disk image with it, on this broken pendrive [05:30] it gave me an error [05:30] but after that, now I can format it! [05:31] I mounted the formatted partition, and a weird "loop device" appears, and I can mount it as many times as I want, it keeps adding it as if they were new different disks. [05:57] For those who want to know: Alfa devices don't ever lock to whatever it is. No country, no TX-power. I wrote them a mail and they are lightningfast with an answer. It boils down to this tutor: https://miloserdov.org/?p=337 So, if you don't get it to work it must be something else. And I'm about to find out what. May take a year or 2 though... [05:57] Hope someone can help. successfully updated openssl to 1.1.1c and openvpn didnt recognize the new version. I still have openssl installed through dpkg but if i remove openssl over 600mb in packages will be removed which I dont want [05:58] on stackfault someone had the same problem. The verified answer was an 'export' command. now openssl version -a doesnt return a response. [06:36] And I can add to this, the aircrack drivers from github don't allow TX power regulation. It's locked to 20 dBm. [06:39] Rexodus: maybe a topic for #ubuntu-discuss ? [06:42] lotuspsyc: this discussion whas here a couple of days ago. That's why I started my previous comment the way I did.

[06:44] hump in -discuss and we can rant all day babe [06:45] Was no rant! But you don't seem to understand that. Discussion closed. [06:59] hello - i was attempting to add a "memo"s account in evolutiom. i can see there are web and caldav choices. but i havent been able to run it with a web provider (eg google). i am willing to host my own server (for myself) but i'd like to know what kind of server evolution expects (to be provided in caldav or web). thank you!

[07:31] I am experiencing a bug on Ubuntu 20.04 where input settings are not getting applied for a USB keyboard and a touchpad. The settings work fine for the laptop's input devices.

[07:40] https://superuser.com/questions/90657/find-out-if-laptop-is-docked-in-linux [07:42] matsaman: thanks for the suggestion [07:43] lotuspsychje: will file a bug on xinput, thanks [07:43] kostadin[m]: some interesting things here also: http://google.com/search?q=dock+keyboard+site%3Aubuntuforums.org [07:44] matsaman: [07:44] * matsaman: it's not dock related. If you just plug the touchpad directly to USB it's the same behaviour [07:45] still, there's stuff about kernel prefs for USB multi input [07:45] anyway [08:28] hello i need some help [08:28] im getting a systemd error on the openvpn start command [08:28] https://www.irccloud.com/pastebin/CqEwU04A/ === StathisA_ is now known as StathisA [08:38] Are these texts the full output of systemd?

A) Set "discard" option in /etc/crypttab, B) Add "allow-discards" in GRUB_CMDLINE_LINUX in /etc/default/grub, C) Add "rd.luks.options=discard" or "rd.luks.allow-discards" options somewhere or D) Something else? [08:52] https://www.irccloud.com/pastebin/HH8NciPk/ [09:17] exut [09:19] Sorry, wrong window. :) [10:09] Hi all, I have suffered a gfx card failure and after replacing, I can't boot ubuntu - Windows is installed on another HDD and it's taken over. Any ideas? [10:09] g105b: you must've done something other than replace the gfx card [10:10] g105b: anyway: https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows [10:10] matsaman: boot failure many times, which caused windows to freak out [10:11] https://paste.ubuntu.com/p/4bNgYYZrXx/ [10:12] I would like it to boot to sdc which is the physical disk with ubuntu on (pop os) [10:14] g105b: if you disconnect the sata cable going to SATA1, what happens? [10:15] matsaman: I get an error, Please insert a bootable medium and reboot. [10:16] Sorry, no that's if I try to boot to that drive from bios - if I disconnect the sata cable, I get a windows recovery error saying a required device has been disconnected. [10:18] I've just run boot-repair from the live usb, I will reboot to see where i get to... [10:20] ... switched to my laptop for IRC. That was a bit silly of me logging in on the live USB. [10:22] boot-repair did nothing :( [10:22] well your paste says it's using efi, AFAICT, so not sure why you'd try with 'BIOS' [10:23] I meant when I press F11 at the start of the boot - is this not BIOS? [10:23] sounds like the 'boot menu' shortcut [10:23] for picking a device to boot from? [10:24] the firmware configurator, though, I know what you're referring to [10:24] Yeah that's what I mean, I can access it from the BIOS screen too so I thought it was the same thing. [10:24] I'm not sure what to do at all, Windows won't boot either but I don't care about that too much. [10:25] hi all [10:25] can someone help with pxe boot istallation of ubuntu 20.04 ? [10:26] i am trying this https://butwt.wordpress.com/2020/06/29/pxe-booting-ubuntu-20-04-installer/ but it is still asking for option during boot time [10:26] i have provided the user-data file as well [10:28] g105b: I thought you said Windows was booting [10:28] can anyone help me please with pxe boot setup for installing ubuntu 20.04 ? [10:29] matsaman: Windows is booting into its recovery crap that does nothing [10:29] matsaman: I am under the belief that the Windows repair thing has tried "fixing" things for me by stomping over my boot records. [10:30] g105b: don't think Windows would do that for sdc [10:30] g105b: what if you unplug all sata cables but the one for sdc, and hook that one up to SATA1? [10:31] matsaman: I've just tried it, and I get the "No bootable medium" error at the POST screen. [10:31] If I look at the boot-repair logs, it says that there is only one OS detected, on sda [10:31] that makes sense, if the Ubuntu disk is plugged into SATA1 [10:32] g105b: anyway, try the other process at https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows the one that isn't 'boot-repair' [10:33] matsaman: ah, thank you [10:33] any familiar with ubuntu pxe installation ? [10:33] *anyone [10:33] ? [10:34] ygk_12345: sorry I tried it once and nothing worked so I put it down to me not being clever enough to understand it [10:36] matsaman: if I type `grub-install /dev/sdc` I get an error saying "failed to get canonical path of /cow" [10:36] g105b does it work at all with ubuntu 20.04 ? [10:38] g105b: /cow? [10:38] anyone here who knows about pxe installation of ubuntu 20.04 ? [10:39] matsaman: yep, that's what it's saying to me. [10:40] and I'm no farmer [10:40] heh [10:41] g105b: that's as root? [10:41] Yep [10:43] g105b: is that with only the one drive plugged into SATA1? [10:43] No, it's plugged in as normal currently. [10:43] I'll try again with only that drive plugged in. [10:44] Although, I'm getting close to just throwing the whole thing out of the window. [10:44] mmm, that would eliminate variables, if you plug in only the drive you're dealing with for Ubuntu, and refer to it as sda [10:49] Weirdly, on what was /dev/sdc2 there is a lot of Windows looking files, as if it's actually been overwritten by Windows! [10:50] On that disk there is a $RECYCLE.BIN and System Volume Information directory. [10:50] That's all alongside a casper, dists and pool directory with Linuxy things in. I think something's really borked, and it's looking like a reinstall will be needed. There goes my productivity. [10:51] hi g105b [10:51] looking at your boot repair log.. [10:52] Shall I run another one, just in case I've messed things up since then? [10:53] g105b: what partition are the OS files on? [10:53] no [10:53] https://paste.ubuntu.com/p/TbT9HSk3bG [10:54] sda is Windows - sdb is a big old disk of data - sdc is my Linux install [10:54] g105b: sdc3? [10:54] says it's encrypted [10:54] g105b: it looks like sda and sdb are gpt partitioned, so that means windows would only boot in uefi mode [10:55] g105b: what does 'sudo efibootmgr -v | nc termbin.com 9999' give you? [10:58] EFI variables are not supported on this system. [10:58] EriC^^ ^ [10:58] g105b: reboot the live usb in uefi mode to troubleshoot [10:59] I need to learn how to do that first.

SInce then I have been upgrading. 20.04 was working fine for me until recently when I decided to finally do a fresh installation. I did a minimum installation so that I could install whatever is really necessary. I observe rather high load averages on the workstation. Any clues? I saw that snap may be causing this [17:30] slowness. Any suggestions?

I just found it last night now formatted as NTFS over what was an ext4 LUKS volume originally. What steps can I take to [18:52] recover this? If I can at least get it recovered enough to open the backup tarball in the volume I should be able to recover all of the data. [19:00] zerohour999: recovery is highly unlikely [19:00] zerohour999: better off just restoring from backup. If that was the backup, then re-backup to it from the original source files. [19:02] The moral here is to always keep a backup in another location as well as a local one. [19:02] @leftyfb I'm willing to try anything, my last backup that I have a copy of on my own computer is two months old. Is it possible to maybe restore files from the cache of nextcloud? I was thinking about reading the logfile to check everything I've uploaded since then and attempting something from there, but I can't imagine that would do much beside [19:02] tell me all the files I lost [19:03] zerohour999: that would be a question for #nextcloud [19:05] Right, nonetheless should I attempt reformatting the drive as ext4 and trying to recover the data that way, or is it almost guaranteed failure because it was a LUKS volume? [19:06] zerohour999: the more changes you make to that drive, the less likely you are to recover anything [19:06] There are professional data recovery services. [19:06] zerohour999: if the data is that important, then you need to contact a data recovery company. Expect to pay thousands of dollars [19:06] But agreed; the more you alter, the more you lose. [19:08] zerohour999: what's the problem? [19:08] EriC^^ what do you mean? [19:09] EriC^^: LUKS partition that was formatted to NTFS. They want to recover the original LUKS [19:09] zerohour999: what's your issue, i just joined so there's no backlog to read [19:09] oh, thanks leftyfb [19:09] there's really no coming back from that, not with the data encrypted. [19:09] zerohour999: you did do a dump backup of the LUKS header when it was created didn't you? [19:10] I believe so, it's been quite some time since I set up the server originally [19:10] davido_, A professional data recovery service would go ever sector vy sector and find data in segments if it is in ascii text for you might bee able to puzzle the pieces back together. Bit really yo have basically taken the disk to the shredder and you have to piece together the strips. [19:12] Younder: I totally agree. But I think that it's beyond what can be fixed in #ubuntu, and that a professional service is about as close as he could come to getting it back. But I think it's a lost cause. a LUKS partition is encrypted. It's already not plain text. Format something else over it, and you lose the semantics that would be needed to decrypt it. [19:13] hi! are there any other terminal file editing tools i should be aware of? for example, cut is a really handy tool. right now i want to insert a comma at the end of each line, how would i approach that? [19:13] dexter: sed [19:14] sed, i heard about that, never used it, let me investigate a bit! [19:14] dexter: you should look up "bash basics" on google [19:14] i know how to do that with bash scripting [19:14] i can write basic bash scripts too [19:15] I dont know any awk though [19:15] perl -nle 'print "$_,"' filename [19:15] To be clear, with LUKS, once the 4KiB header is overwritten without backup the data is gone [19:16] dexter: if you haven't used sed, then you still have a long way to go with bash scripting [19:16] haha, yeah fair enough, i primarily use bash for automation, rarely over 80 LoC [19:17] i prefer programming in C, bash is purely for lazy automation for me, until now, gotta learn some sed [19:17] no bash script should exceed 80 loc :P [19:18] my backup script is about 400 lines [19:18] @TJ- understandable. I had a cronjob to run weekly backups on the drive so I at least have a list of the files, if I restore my october backup, what's the easiest way to run a comparison to see what lines of text (aka files) are missing between the old backup? [19:18] upon reading the basics of sed, i get the idea that (n)vi(m) uses a lot of sed in the background, or at least the same syntax [19:19] dexter, same syntax, yes [19:19] zerohour999: rsync dryrun [19:20] all my life i've been told that the plural of regex is regrets, and now i'm told to learn sed, which uses alot of regex ^-^ [19:21] @leftyfb will that work with comparing the new file list to the cronlog? [19:21] zerohour999: not without massaging the data [19:22] zerohour999: nothing will do what you're looking for out of the box [19:22] leftyfb: yo what's that command again to tell me how fast my boot time is? :) [19:22] zerohour999: but you could write a script to pull data from the cron log and write out a file that rsync can parse [19:23] Deano59: systemd-analyze is what all the cool kids are using these days [19:23] @leftyfb true true, I'll give it a shot. Thank you for your help! [19:23] thanks. :) [19:29] dexter, vi is the natural home of ed, sed, and ex so regex is a big part of it. If you want a graphics based editor that is less regexp based perhaps Atom or Code Studio? [19:31] Younder: VSCode and Atom use Electron, i mean, about regex was joking, but electron eats up your pc [19:31] i mean 600MB for teams [19:31] RAM usage [19:32] dexter, my machine has 128 Gb.. depends on what yo have available. But you already run a web browser. Atom is basically chromium and javascript [19:40] nano is the basic editor in ubuntu [19:42] Otherwise EMACS is still popular and available in text mode. [19:43] Younder: emacs >< vim [19:43] :) [19:46] Anyone able to parse why a fresh install of MariaDB fails? https://gist.github.com/LeamHall/04615d6546f4b2bb4c681dd922db783d [19:46] I installed Mysql, then removed it, to install MariaDB. [19:47] Ubuntu 20.04, Mariadb installed via apt. [19:47] leftyfb, I use both. EMACS is best for Common Lisp and has a good LaTex mode. vim for command line editing. I do a lot of ssh and command line editing of files. Also GUI's like Code Studio of Eclips. [19:53] leitz: you should probably purge both then reinstall mariadb [19:55] leftyfb, can you purge after it's already been removed? I removed mysql before installing Maria. [19:55] apparmor caused an initial issue for Maria, but I've removed that as well. [19:59] Reinstalling mysql so I can purge it properly. :) [20:00] You REMOVED AppArmour? Good grief.. [20:03] leftyfb, mysql doesn't want to be removed. :( [20:03] installed mysql-server-8.0 package post-installation script subprocess returned error exit status 1 === denningsrogue2 is now known as denningsrogue [20:16] guys help [20:21] are you melting? [20:22] Sounds pretty cheesy to me... [20:22] Sorry, couldn't resist. [20:22] Looks like I arrived late of a setup for a punch line. [20:23] I'm sure we can string this along for a while. [20:25] I have an Off-Topic question, but I don't really know where-else to ask. I'm trying to build cross binutils, build=ubuntu 18.04, host=win32, target=x86_64 linux - Everything builds if I exclude GDB (which I need), when I include it I get "configure: error: GMP is missing or unusable [20:25] " [20:25] The question it's self being, "Any ideas?" [20:26] KF5WYX: is that on Windows sub-system for Linux? [20:26] TJ - No, I'm running an Ubuntu 18.04 vm, trying to build Mingw hosted binutils to target linux. [20:27] I'm about to paste-bin my build script, but should also point out that I do not know what I'm doing (I'm a developer but entirely unfamiliar with the GNU tool-chain) [20:28] https://paste.ubuntu.com/p/fZdD9mZsSq/ <- the bit at the top is just installing packages, many may be unrequired. --disable-gdb is added, in which case everything works. [20:29] https://paste.ubuntu.com/p/JWD4SMyw4T/ <- when gdb enabled [20:30] KF5WYX: oh! does the package './configure --help ' script indicate it takes options related to gmp? e.g. --with-gmp-include [20:31] ./configure --help | grep gmp [20:31] --with-gmp-dir=PATH this option has been REMOVED [20:31] --with-gmp=PATH specify prefix directory for the installed GMP [20:31] --with-gmp-include=PATH/include plus [20:31] --with-gmp-lib=PATH/lib [20:31] --with-gmp-include=PATH specify directory for installed GMP include files [20:31] KF5WYX: or possibly --with-gmp-lib or similar - those examples are from the 'mpc' package so are unlikely to be exactly the same [20:32] KF5WYX: so, first check if you've got libgmp-dev installed [20:32] TJ: I've tried --with-gmp=/usr/lib/x86_64-linux-gnu with no change [20:32] TJ: I do have libgmp-dev [20:34] KF5WYX: I've just checked where that package puts its files; it ought to be found but try "./configure --with-gmp=/usr ..." just in case that helps [20:34] KF5WYX: configure should created a config.status and config.log which, when examined, might indicate why gmp isn't being discovered [20:34] TJ: Thank you, trying it now - It'll take some time to get results due to single-threading make. [20:36] KF5WYX: generally when these things happen I open the ./configure script and search for the section that detects/sets the library options, so I'd do 'less configure' and then /gmp and read how it tries to detect the libraries it needs [20:38] TJ- --with-gmp=/usr did not change anything. I did try reading the configure / make scripts and got deep in variables, I'll look again. Also examining config.log since I'd previously not known it was there. [20:39] KF5WYX: FYI most -dev packages ship the required build flags/options in package-config files; libgmp-dev puts them in /usr/lib/x86_64-linux-gnu/pkgconfig/gmp.pc [20:39] KF5WYX: might be worth reading that [20:41]
