[00:00] o/ [00:00] \o === Juan- is now known as Juan [00:12] Hello, will altVR work in ubuntu? [00:13] Hello. Will altspaceVR work in ubuntu? [00:13] can you get it from the repo? [00:14] Well I saw they have a github.. Will it work if I clone from there? [00:16] mago, url? [00:16] https://docs.microsoft.com/en-us/windows/mixed-reality/altspace-vr/getting-started/system-requirements [00:16] if it is not in our repos, we officially do no support it. [00:16] looks like a no [00:16] It seems its all for windows, thats what i thought.. [00:16] oerheks they have this github: https://github.com/orgs/AltspaceVR/repositories [00:16] you could try it with wine but I wouldn't spend any money on trying it.. [00:19] Someone stole my nick? But i have it registered.. [00:20] how is that an ubuntu support issue? [00:20] you seem like logged in [00:20] Well that was not ubuntu related, ill give you that.. [00:22] sarnold It's been on pause. I started getting frustrated and hungry, so I ate. Now I'm back. === Mago84 is now known as mago [00:22] Guest94: woo, I think I did much the same :) lunch and then a few meetings.. [00:23] I've wasted the entire day on this. [00:24] somebody wanted me to modify grub.cfg and start from there instead of what you suggested. That's more or less when I took a break. [00:25] sarnold I'm not even really sure what he wanted me to do or how it would help. [00:25] Going back to AltspaceVR will the mac version work easier in Ubuntu than the windows one? [00:25] they may have had a good reason for their suggestion; my suggestion was based on the strong hope that you were 100% right by nailing it down to the kernel packages [00:25] Did you see the packages I posted? [00:25] downgrading 5.11 on 20.04 ,.. [00:26] yes, that's what I need to do. Downgrade back to 5.8 [00:26] i'd say reinstall [00:26] And then after that, I have no idea how I'm supposed to get updates. [00:26] oerheks ugh. Why? [00:28] did you use the testing kernels ? or linux-hwe-5.11 from the ppa kernel team [00:28] I used whatever came down. But I can be more specific.... https://paste.ubuntu.com/p/z9CwgRjpVW/ [00:33] yay for specifics :) that's indeed the HWE kernel stack, it matches what's in my apt lists from yesterday [00:33] (my archive mirror is off at the moment, so I'm a day out of date) [00:36] log from /var/log/dpkg.log https://paste.ubuntu.com/p/cndsnPTXRR/ [00:37] so... do I proceed with the sarnold plan? [00:39] Guest94: well, hard to say. I can see some real benefit to the idea of modifying the grub configuration so that you ought to be able to more easily select fallback kernels, etc [00:39] OK [00:39] What do I modify? [00:39] Guest94: I'd suggest doing that by editing /etc/default/grub instead of the grub.cfg file [00:40] ok [00:41] Guest94: I'm not 100% sure what to put in there, this is what I've got in mine: https://paste.ubuntu.com/p/WY87qg8YzB/ and I think the GRUB_TIMEOUT=5 is most immediately useful, but perhaps some of the others are important in your case [00:41] This is the file I was looking for! I couldn't find it before, didn't know where it was or what it was called but... this is more or less the contents I couldn't seem to find. Thanks! [00:42] It's the quiet splash for one thing... [00:44] and this GRUB_TIMEOUT_STYLE=hidden [00:44] I think [00:46] I wish I had kept better notes of which changes I introduced vs what was already there :) [00:46] Guest94: My grub file " GRUB_TIMEOUT_STYLE=menu " As I do multi-boot and I want to always see the menu. [00:46] Bashing-om Thank you! I was just searching through the info doc and not finding it. [00:46] sarnold: I do have my original grub file - want it ? [00:47] Bashing-om: oh that'd be handy yeah, thanks :) [00:49] sarnold: Guest94: My original grub file: https://termbin.com/w69i . [00:50] ok, running update-grub unless someone has an objection? [00:50] Bashing-om: man I mangled mine. heh. thanks [00:52] sarnold: Should see how I have mangled up mine - I make it a practice to alwsys make a back-up of any system file I edit :D [00:52] Seeing no objections... I am now running update-grub [00:54] I wish someone had objected... I'm not in the chroot environment. [00:54] Luckily, I didn't run it. [00:54] Phew [00:54] So.... is this going to work w/out running update-grub? [00:55] Guest94: My excuse - I have not kept a close eye on what you are doing :P [00:55] No... I guess I need to chroot [00:55] Bashing-om Nobody is. Good thing I don't have any matches. [00:55] Guest94: nice catch :) [00:56] so we agree on chroot then? [00:56] yes === Starmina_ is now known as Starmina [01:06] ok [01:07] were you able to get to a menu of previous kernels with this change? [01:07] or did it all go even more sideways? [01:07] not ready yet [01:07] aha [01:08] busy losing my mind === y0sh| is now known as y0sh- === y0sh- is now known as y0sh_ [01:18] argh [01:19] sarnold https://paste.ubuntu.com/p/HFG6XZgh6v/ [01:19] Guest94: hmm, did mounting your root filesystem on to /mnt fail? [01:20] I was wondering how it was supposed to be mounted! Let me add that in. [01:21] sarnold OK, that worked... as far as all the errors are concerned. [01:23] Guest94: good good [01:24] OK, I have entered the environment [01:24] expected device mounted on root. So far so good. [01:25] so.... grub-update here? [01:25] just to double-check, did you edit the /etc/default/grub that's in this chroot environment? [01:26] sarnold Yes. Thank you for making it easy. Bouncing back and forth between files let alone environments is confusing. [01:27] So... grub-update. [01:27] update-grub [01:27] which of course isn't in the environment :/ [01:28] on my focal system, it's in /usr/sbin/update-grub [01:28] uh oh... grub or grub2? [01:29] on my system, update-grub2 is a symlink to update-grub [01:29] let me verify [01:30] yes, same here [01:30] here goes. === keypushe- is now known as keypusher [01:33] sarnold https://paste.ubuntu.com/p/jSkJSyJ6xr/ [01:34] sdd1 appears to be my CDROM so, that's fine I guess. [01:35] maybe run it again after I reboot? [01:35] Guest94: woo, looks promising [01:36] Guest94: I'm a bit surprised by the 16.04 messages, but maybe that makes sense. heh. [01:36] Guest94: you probably don't need to re-run it after the reboot [01:36] I have multiple disks, I've not yet cleaned out the older ones. [01:36] cool [01:36] then it makes sense :D [01:36] well I presume I want to get my cdrom in there too? [01:37] Nah, I guess that doesn't matter. [01:37] I don't boot off that drive. [01:37] nah, that probably won't happen much :) [01:37] and you can always fiddle with uefi boot order in case you're actually booting to a cd [01:37] besides... it will fix itself next kernel update [01:37] ok, so... reboot now? [01:37] I think so, yeah [01:38] OK, see you on the other side. Back soon I hope. [01:53] On a machine with 1 cpu and 4 real cores (with hyper threading enabled 8 cores), when I look at the cpu load averages, should I measure it against the 4 real cores or the 8 hyper threaded cores? [01:54] neither [01:55] alzgh: well, it's not exactly related... load average shows you how many processes are runnable or waiting for .. long IO? disk IO? something similar .. and doesn't really matter about how many CPUs are online to run those processes [01:57] sarnold Still won't boot. still doesn't show menu. Just a blank screen after I choose the boot device. With that said, I'm exhausted and exasperated and I need a nap. Appreciate you and everyone else helping. BBL [01:57] Guest94: dang :( twenty minutes, I was getting worried, heh [01:57] Guest94: good luck [01:57] sarnold I'm talking about load average from `top`s first line. Doesn't a "1" in the load average roughly corresponds to on cpu core load of work? [01:58] I mean the 1 minute, 5 minute, and 15 minute from `top`'s first line. [01:58] alzgh: it could also be one process stuck waiting on disk io, waking up, doing something with it, then doing another disk io [02:00] this would even out when we look at the 15 minute average, no? [02:00] it depends what the processes are doing and for how long they do it :) [02:00] true [02:00] it's just one way of viewing the system, and it's not really the most useful [02:01] I think it was more useful on other unix systems but even then, it's a pretty minimal view of things [02:02] for example, when I got a dual-xeon system, I did a bunch of kernel compiles to try to figure out what it could do, and running "make -j 300" in the kernel sources gave me the *best* performance; it brought the load average around 300 for almost three minutes, but it was the fastest; I only had 16 cores, 32 threads. [02:05] That makes sense sarnold. What other more reliable ways are there to monitor a system for resources? [02:07] vmstat 1 is very handy -- it shows runnable and blocked processes, a rough guideline of how memory and swap is being used, how much disk traffic there is, and percentages of cpu utilization [02:07] oh yeah, I prefer vmstat -w 1 .. I'm not quite accustomed to it yet :) [02:08] I've heard good things about the netdata package, some screenshots on https://github.com/netdata/netdata [02:09] and this suite of tools (in the bpfcc-tools package) is fantastic for seeing different cross-sections of your computer https://github.com/iovisor/bcc#tools [02:09] but there's dozens or hundreds of choices, all with various pros and cons [02:10] I'm off for the night, have fun :) [02:10] thanks, this gives me a good start [02:10] good night [02:11] o/ :) [02:49] does ubuntu not let you set up encrypted LVM via the manual installer anymore? I tried on 21.04 and I can choose "physical volume for encryption" but there's nothing related to LVM before or after [03:32] Hello [03:33] Does any one know about RUBERHOUSE? [03:33] Is the file System from julian assange. [03:40] Does not compute. [03:41] i know of one package called "surf raw" originally maintained by assange [06:18] * ash_worksi hopes people are alive atm [06:40] ash_worksi: just ask your question :-) [06:41] polve: haha, sorry, yes, I was going to but got distracted by another channel :P === frickenate is now known as frickenate_ [06:42] it was recommended that I use `shopt -u progcomp` in order to ease tab-completion for tedious file prefixes (timestamps); seeing as how ymmv between linux distros I wanted to check with the pros if they thought that was a good idea? [06:46] understand that I use ubuntu pretty close to just out-of-the-box; so when it comes to such a recommendation I get afraid that it might intefere with other ubuntu-specific niceties [06:46] I just purge bash-completion instead === frickenate_ is now known as frickenate [06:47] The system won't be affected in any case, it's just about your own personal preference... [06:49] geirha: what do you mean by 'purge' ? [06:51] ash_worksi: sudo apt purge bash-completion [06:51] I.e. uninstall the bash completion package [06:51] I see [06:52] that shopt does kill docker autocomplete [06:52] you can probably override the completions for that single command [06:53] assuming bash-completion does not override it again [06:53] complete -o default -o bashdefault ymmv [06:56] geirha: is that assuming i use the shopt ? [06:56] no, the shopt disables programmable completion completely, leaving you with default completions for all commands [06:57] okay; so the idea is supposed to be `complete -o ... ls_or_something` ? [06:57] oh no, I see [06:57] I think [07:02] ah, I somehow read ymmv as the command with broken completions [07:02] so if it's for multiple commands, then maybe the shopt is a good idea. You can re-enable it with -s instead of -u [07:10] geirha: yeah; well, it's only when I jump into a directory with timestamp prefixes [07:11] I just hate that I can't every autocomplete more than like 3 characters before having to really peer at the ls of everything [07:11] and a jumble of numbers is not exactly easy for me to read [07:12] what format are the timestamps in? seconds since epoch? === ubuntu is now known as Guest8071 [07:18] geirha: genearlly $(date +'%Y%m%d_%H%M%S')_something.ext [07:19] ok, I don't quite see the problem, then [07:22] Can I use apt-listchanges to see the changes in packages which are current candidates for apt upgrade? [07:29] This is pretty stupid https://bugs.launchpad.net/ubuntu/+source/shadow/+bug/1927078 [07:29] Launchpad bug 1927078 in shadow (Ubuntu Impish) "Don't allow useradd to use fully numeric names" [Low, Fix Released] [07:30] How about the bug gets fixed in systemd instead, rather than imposing something this drastic on the entire userbase when the bug report even says: "Users may have scripts that are currently using numeric usernames and these scripts will break as a consequence of this deliberate change in stable Ubuntu releases." [07:32] "ooh but the user names look like uids, we don't like it and we're changing it anyway" .. sigh .. shades of Firefox dev team imposing their preferences on the user base [07:35] I'm more curious why they were allowed to begin with [07:36] That's a way better argument, but it doesn't change anything about the lack of care imposing a drastic change which will break things across the board [07:37] How to list only the available security updates in Focal? [07:37] Seth Arnold in the bug report uses a Perl example to argue ambiguity. sudo perl -e 'print "muahaa\n" if $< == "0x0";' .. and then says: " the language sure doesn't help " ... which is highly misleading, since the proper string comparison is done with "eq" not with "==" and fails as expected. [07:42] Anyways, I know FOSS, and I know how stubborn devs are about imposing high impact changes and delegating the PITA to the user base. This is one of those incidents where there is no accomodation whatsoever, and no consideration of cross-distro compatbility. I don't even use numeric user names, I'm just irritated with the flippancy of the decision. [07:43] And with the apparent approach of (not) fixing bugs in one subsystem by imposing restrictions on another [07:48] Also, regarding the Perl example, why the hell would one *ever* compare the real *uid* of a process to a user *name*. The example is so deliberately contrived. [07:48] though looking closer, it's really only user{add,mod,del} that will be affected. numeric usernames will still work, you just can't create them with useradd anymore [07:49] Yeah [07:49] Que sera sera, I guess [08:53] geirha: sorry, I got side-tracked again [08:54] the probalem is that I generally can't use the button when I want to autocomplete files and it's hard for me to read timestamps in a list of other timestamps [08:55] so rather than having to type `vi 20210805_025456_add_^I` I'd rather type `vi *_add^I` [08:55] I feel like you probably already saw me saying that in #bash [08:56] but I guess `shopt -u progcomp` is pretty good for that === beaver is now known as pong [10:20] https://askubuntu.com/questions/1245020/xrdp-on-ubuntu-20-04 [10:21] wondering why it is so problematic with those remote desktop things nowadays on ubuntu [10:22] that whole "universe" repository does not seem to be a very good concept, so much stuff is simply left to rot there without much maintenance :/ [10:58] Programs in universe are mostly maintained upstream, not in Ubuntu [10:59] yeah, it's kind of an anachronism [11:02] Ubuntu is an anachronism these days... [11:11] Hi [11:11] I am here from China [11:12] emmm.Bye === Juan- is now known as Juan === diskin is now known as Guest1915 === diskin_ is now known as diskin [12:09] hello! emergency here: mount: /: cannot remount /dev/sda1 read-write, is write-protected.

[12:13] I'm at command line [12:14] everything I do is an input/output error [12:14] also reboot doesn't work [12:14] gonna try with sysrq [12:16] Hi.., i have a question on ubuntus repository..., there seems to be repeatedly the version 8.04.1 in the all the directories of version 8.04.XXXX , no matter if 8.04.1 or 8.04.2 , 8.04.3 , or 8.04.4...., that seems to be redundant data.., right ? [12:17] link old-releases.ubuntu.com/releases-8.04.4/ [12:18] link old-releases.ubuntu.com/releases/8.04.4/ [12:19] McE: those releases are long eol, whats your purpose with this exactly? [12:21] no..., its only about the redundant data.., or is the data not redundant ? that is all i want to know for now...., seems to be a lack of proper maintaining to me..., or am i wrong... ? [12:22] so the content of 8.04.1 is exactly the same as the content of 8.04.4 ..... [12:23] as far as directories are concerned... [12:25] even the links to 8.04.1 pc-isos , are not pointing to 8.04.1 but to 8.04.4..., === lordrishav is now known as LordRishav [12:48] Hello [12:48] I have a problem [12:48] ask away KsamaDa [12:49] lotus|NUC where ? [12:49] lotuspsychje [12:50] here in the channel KsamaDa ask your issue with all your details [12:50] lotuspsychje ok [12:50] I can't seem to have both the micro and output audio working in the same time.

After all, doing anything as root when root is not needed is bad, and especially bad with software that connects to the Internet. [12:55] KsamaDa: whats your current kernel please? [12:55] 5.11.0-25-generic [12:55] KsamaDa: we are seeing some recent bug reports on audio on kernel 5.11 so it seems lately [12:55] * the problem still when using headphones as well [12:56] KsamaDa: like this for example bug #1939010 can you check if this is you?

[14:31] lsm5, one could ask for the update, if you have a reason, see !SRU [14:31] !sru [14:31] Stable Release Update information is at https://wiki.ubuntu.com/StableReleaseUpdates [14:31] 1.16.6 12 juli [14:32] oerheks: are you saying it's already released? i can't seem to find it using `golang-1.16` package [14:32] it only installs 1.16.2 [14:32] no, it is not in our repos, yet [14:32] but attention could speed things up [14:33] ack, i see, thanks [14:33] lsm5, i think 1.16.6 is available via snap, if i'am not mistaken [14:34] ioria: ack, trouble is I need to build a few packages like podman/buildah etc. on OBS, unlikely I can use snap for i [14:34] it* [14:34] oh correct; https://snapcraft.io/go [14:35] anyway, thanks oerheks and ioria i'll try to follow the SRU [14:35] have fun! === genii is now known as genii-away [14:39] :) === genii-away is now known as genii === Mikro is now known as leo === leo is now known as Leo [15:06] Hi, I can't mount one of my ext4 partitions using mount command any longer, it tells me either the Superblock or partition table is corrupted. [15:07] TestDisk doesn't seem to have any complains about either hoewever [15:13] zteam, how about fsck ? [15:13] https://help.ubuntu.com/community/FilesystemTroubleshooting [15:14] oerheks, just a moment [15:20] oerheks, the weird thing is that it appears to be happening randomly, sometimes the partition is automounted just as it's supposed to do, other times it fails for some weird reason [15:22] oerheks, no complains from fsck this time around [15:25] dmesg -wH doesnt seem to list any complains either, I will try to reboot and see if still mounts as expected [15:37] Nope, my problem is still here, it just happens randomly :/ [15:37] journalctl -b -0 shows messages from the current boot, journalctl -b -1 from the previous boot [15:47] oerheks, interesting thanks :) [15:51] zteam: how os the file-system configured? in /etc/fstab, as a systemd.mount unit, and automount ? [15:52] TJ-, I need to doublecheck this, just a moment [15:53] zteam: also of importance, does the system shutdown/roboot cleanly each time or is something hanging - its possible the journal isn't being closed [15:54] TJ-, /etc/fstab how to tell if it's using systemd.mount or not? [15:55] I'm not really sure what to look for with journalctl either [15:56] zteam: it'd be either/or ... at start-up systemd, before anything else, executes its generators. one such is systemd-fstab-generator which converts fstab entries into systemd.mount units [15:56] zteam: since there is a .mount unit for your device there is a log you can look at for it. Identify the .mount unit name and then do "journalctl -u XXXX.mount" [15:57] zteam: .mount unit names are the path to the device with / replaced with - [15:58] TJ-, okey, this is fair beyond my knowkedge, I can post my fstab if you like :-) [15:58] zteam: correction. path to mountpoint! as in "/dev/mapper/containers /var/lib/containers ext4 ..." would result in var-lib-containers.mount unit [15:59] zteam: so as you'll know your mountpoint path, you can check the log. In my example above I'd o "journalctl -u var-lib-containers.mount" [16:00] what is nice is that system-fstab-generator /also/ creates an fsck unit to check the mount before it is mounted [16:01] TJ-, I'm using a luks-encrypted harddrive it's indeed inside a /dev/mapper/ [16:01] zteam: what's the mountpoint ? [16:04] TJ-, /media/Ny%20volym [16:04] Hm, %20 [16:04] zteam: so the unit would be media-Ny%20volym.mount [16:05] zteam: try "journalctl -u media-Ny%20volym.mount" [16:05] zteam: you'll likely need to jump to the end of the log. Easiest is to press capital G in the pager [16:05] here is a dump of /etc/fstab https://paste.ubuntu.com/p/MtcPvDhdbt/ [16:10] TJ-, it complains about the superblock https://paste.ubuntu.com/p/HM8NShGNhs/ [16:11] zteam: are you booting multiple OSes that each access this same file-system? [16:13] TJ-, nope, only Ubuntu 21.04, also this paste is in English (sorry for the mistake) https://paste.ubuntu.com/p/3dyXmg9g7k/ [16:15] https://www.linkedin.com/pulse/non-nonsense-way-configure-apache-ssl-termination-varnish-gjoko-pargo/ [16:15] I follow the last setup for systemctl and I get errors [16:16] failed to load environment files: no such file or directory [16:16] zteam: that's ok, I can read it :) [16:16] genii, Yep, it's because the mount point contains a space [16:17] fstab doesn't like normal spaces :P [16:17] zteam: the only thing I can think of seeing as the log seems to show unmounting being done is that some process is writing random data to the file-system's metadata area whilst in normal use. That'll not be detected until the file system is next checked [16:20] zteam: I'm mostly wondering why /media/Ny%20volym instead of /media/Ny\ volym [16:21] TJ-, sometimes the system indeed shows some error about that, now that you mention it, would that be logging in /var/log/syslog ? [16:23] genii, yeah I know, it works as intended for bash and stuff, but it doesn't look to pretty in Nautilus for example [16:23] Ah, ok [16:29] genii, Yep, you can't use mount-points with spaces in /etc/fstab but you can add %20 to a mount point this way you can still reach it as if it was named "Ny volym" :-) [16:29] zteam: it's be in the main journal. If you have an idea of some unique text in those errors you could try grep-ing for it with "journalctl | grep 'search-term' to narrow down the time range, then use journalctl --since="" --before="" to look at all messages around that time [16:29] Hi all. I'm running an app in Wine, and when I start it as regular user my audiocard drops out for a second. When I start wine as root it doesnt. [16:29] %20 is just the hexadecimal encoding of the ASCII value of a space (32 decimal, 0x20 hexadecimal) [16:30] When I run winecfg as regular user I dont see any errors printed on stdout/err though. [16:31] zteam: I think if it's encapsulated within single quotes it works, but I haven't tinkered with the fstab in a while to remember exxactly [16:34] m1dnight, never run wine as root, I personally just use PlayOnLinux or Lutris then using wine, it makes it easy to follow the logs from Wine as well as tinkering with Wine for you [16:38] TJ-, isn't there any trick to ask the journal about which files got created last? [16:48] I'm back === Abrax- is now known as Abrax [17:27] Hello, how do i rename all files in folder? [17:27] mago: how? why? [17:28] Im trying to batch convert acc files to mp3 but the regex breaks... [17:28] Cuz my file names have spaces and quotes ' " in them... [17:28] So in need to rename to easier file names.. [17:28] using bash is one easy way: for i in *.aac; do echo "$i" "${i%.aac}.mp3"; done [17:29] the 'rename' package in universe is also a lovely perl app [17:29] you can do things like: rename 's/\.aac/\.mp3/g' *.aac -n [17:29] (-n is dry run, re-run without if you like the output) [17:30] matsaman im not sure if that did something.. I runned the command but the files stayed the same.. [17:30] you might have a rename.ul executable already installed, too, and that's ... mostly inferior to everything, IMO =P [17:30] mago: yes the echo one uses echo instead of 'mv' on purpose, so you can ease into it [17:30] the 'rename' one uses -n, which is for dry run [17:31] I understand not.. [17:31] for i in *.aac; do mv -n "$i" "${i%.aac}.mp3"; done would probably be okay to do the actual rename [17:31] But that will just rename not convert.. [17:31] oh convert, then you want ffmpeg [17:31] I think i need to change the file name not the extension.. Yes but ffmpeg break cuz they have weird names... [17:31] mago: you were asking about renaming, you didn't mention converting. Do you want to rename or convert? [17:32] for i in *.aac; do ffmpeg -i "$i" "${i%.aac}.mp3" Thats what i was trying: for i in *.aac; do ffmpeg -i "$i" -vn -ar 44100 -ac 2 -b:a 192k "${$i/aac/mp3}"; done [17:32] there are GUIs, too [17:32] like um... what is it called [17:32] aac to mp3, only possible if it is unencrypted [17:32] Thats an example filename: '5 Aug, 18.29(2).aac' [17:33] mago: filename won't likely matter [17:33] else you end up with a 64 bit mp3 :-D [17:33] Can you help me correct that command: for i in *.aac; do ffmpeg -i "$i" -vn -ar 44100 -ac 2 -b:a 192k "${$i/aac/mp3}"; done [17:33] mago: https://stackoverflow.com/questions/22766111/ffmpeg-not-working-with-filenames-that-have-whitespace [17:33] Probably is the regex [17:33] mago: why do you care about -ar and -ac and -b:a ? [17:33] Someone is requesting those specs.. [17:34] oh okay [17:34] Like im making an audio for an online radio program.. [17:34] mago: if you add mp3}" What is the sources package for linux modules? [17:35] matsman it says bad substitution [17:36] fling, on launchpad [17:36] matsaman it says bad substitution [17:36] Sorry: bash: ${$i/aac/mp3}: bad substitution [17:36] mago: do it the way I said, then [17:37] for i in *.aac; do ffmpeg -i "$i" YOUR_OTHER_OPTIONS_HERE "${i%.aac}.mp3" mago: if you want a GUI there's 'handbrake' in the 'universe' repo [17:38] you'll have to hunt down the little places to specify all your rate options and that [17:38] but you won't have to worry about substitutions [17:38] Ok, that was working, it was a regex issue then..? [17:39] Thanks a lot matsaman :) [17:40] check the quality of the 1st mp3? [17:41] mago: something in the substitution syntax possibly yeah [17:41] it's (trivially) less efficient, but if you want to avoid having to deal with bash's weird syntax, you can instead do things like: "$(echo "$i" | perl -pe 's/\.aac/\.mp3/g')" [17:44] oerheks: do you have a link? [17:44] oh you could have found it by now [17:44] google linux-modules launchpad [17:45] oerheks: zfs is there right? [17:45] zfs.ko === sig_9 is now known as bebop [18:13] Reading the man pages is a not so easy skill in itself [18:15] hello [18:15] how can I remove keys added with `wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -` [18:16] ? [18:16] sort of a low-tech guy, wanting to dual boot my laptop (win10/ubuntu 21)... however, my main question is how to do this with 2 hd's? i want one only for starting up (which is my smallest) but then i want my large one as main hd for running everything within ubuntu [18:18] anyone? [18:19] !patience | varaindemian [18:19] varaindemian: Don't feel ignored and repeat your question quickly; if nobody knows your answer, nobody will answer you. While you wait, try searching https://help.ubuntu.com or https://ubuntuforums.org or https://askubuntu.com/ [18:19] `apt-key list` gives you the list, `apt-key del {{key_id}}` removes a particular key from apt's store [18:22] alzgh which one is the key id? [18:22] I see too many things there [18:22] uid [18:22] ? [18:23] haha, I want to that too. I'll search that if no one chimes in. [18:23] *to know [18:23] ok i've got ubuntu 20.04, i have systemd-networkd, and networkctl gives me: 2 eth0 ether routable pending, runlevel says unknown [18:24] and resolv.conf tells me # No DNS servers known. and i wonder how i'd debug/fix that? [18:24] first systemd failed booting because there was /etc/rc.local (that file is gone now) [18:26] tarzeau__: server or desktop? [18:26] leftyfb: i call it desktop, but it's mounted in the serverroom [18:26] tarzeau__: ok, so desktop. Why can't you use the Network Manager GUI to connect to a network? [18:27] leftyfb: ugh, because when i have 200 machines, i don't want interactive guis? === entuland_ is now known as entuland [18:27] so we don't have network manager, it's removed/purged/gone/nonexistant [18:27] tarzeau__: ok, so have you completely disabled Network Manager and are just using netplan/networkd to manage the network? [18:28] leftyfb: no netplan, just systemd-networkd [18:28] tarzeau__: why not netplan? [18:28] leftyfb: because some collegues think, we don't need another layer on top of it [18:28] @varaindemian Do you have access to the desktop? If so, Software & Updates -> Other Software -> remove the checkmark for the rep key you want to remove. [18:29] but that's how the config file looks: https://bootes.ethz.ch/host.network [18:32] i wonder how can i tell systemd-networkd or networkctl to retry to do the same as when i had dhclient and would run it [18:32] normally i'm able to google such things myself. but whatever is related to systemd, i'm having trouble to find anything useful [18:32] alzgh: varaindemian is looong gone. ;-) something along the lines of this could have worked: mkdir /tmp/x; gpg --home /tmp/x --list-keys &>/dev/null; wget -qO- https://www.virtualbox.org/download/oracle_vbox_2016.asc | gpg --home /tmp/x --import &>/dev/null; gpg --home /tmp/x --list-keys --fingerprint; rm -r /tmp/x [18:33]
