| daftykins | i can't for the life of me work out what creates the paths /usr/lib/modules/<kernel version here>/ | 02:18 |
|---|---|---|
| daftykins | i have a VM with those and a VM without, the one without is unable to load the xenfs module i'm after | 02:18 |
| daftykins | i've been running dpkg -L against the kernel, kernel module and kernel header packages but nothing seems to create the above path O_O | 02:19 |
| daftykins | ok ignore *all* that xD | 02:25 |
| daftykins | modprobe claimed the module wasn't there, "sudo depmod" updated its' opinion and now it's loaded fine | 02:26 |
| sarnold | \o/ | 02:26 |
| sarnold | but I'd still like to know where /usr/lib/modules comes from.. | 02:26 |
| sarnold | are they owned by another path in dpkg, that's symlinked, and thus you can't find them with this name? | 02:27 |
| daftykins | it's a total mystery, on my normal 20.04.1 VM, i see: | 02:28 |
| daftykins | drwxr-xr-x 5 root root 4.0K Oct 20 02:20 5.4.0-52-generic | 02:28 |
| daftykins | inside /usr/lib/modules | 02:28 |
| daftykins | inside that are - https://termbin.com/0r3t | 02:28 |
| daftykins | but yeah, just can't get a handle on what puts them there | 02:29 |
| daftykins | oooh ok, my bionic machine doesn't have that path - one comment i can make is that the VM that does have this path has been doing some compilation | 02:29 |
| daftykins | could build-essential do something with this o0 | 02:29 |
| Bashing-om | daftykins: Bog standard bare metal: "sysop@2004x-c:~$ ls -al /usr/lib/modules/ >> ls: cannot access '/usr/lib/modules/': No such file or directory". | 02:33 |
| daftykins | indeedy! so i was wrong earlier to think it was default | 02:34 |
| lotuspsychje | good morning | 03:38 |
| ducasse | good morning | 06:23 |
| mgedmin | daftykins: kernel modules live in /lib/modules, but on recent ubuntus /lib is a symlink to /usr/lib | 07:04 |
| === PowaBanga_ is now known as PowaBanga | ||
| lordievader | Good morning | 07:29 |
| marcoagpinto | Heya | 08:42 |

| daftykins | mgedmin: that wasn't the case on any of my focal VMs | 17:28 |
| mgedmin | the /lib symlink? | 17:36 |
| mgedmin | huh, I though usrmerge was installed by default, but I see that it's no longer the case | 17:36 |
| daftykins | i ended up throwing in the towel and going to bed, if i "apt install --reinstall" 'd the linux-modules package for the running kernel, i got the xenfs module back that i wanted, but for some reason on every reboot it disappeared again | 17:37 |
| daftykins | i have absolutely no idea what was causing that | 17:37 |
| mgedmin | hmmm this laptop was installed from ubuntu 9.04, never had usrmerge installed, and has /lib -> /usr/lib symlink (plus /bin, /sbin, and a few /lib{32,64,x32}) | 17:38 |
| mgedmin | that is very strange | 17:39 |
| tomreyn | /lib and /usr/lib are separate on an ubuntu installation from 2015, which is now at 18.04, and went through 14.04 and 16.04 | 17:48 |
| tomreyn | an installation i have here, this wasn't meant to be a generic statement. | 17:49 |
| mgedmin | I've an ubuntu 18.04 server originally installed in 2009 that still has separate /lib and /usr/lib | 17:52 |
| mgedmin | afaiu ubuntu will not force a migration to unified /usr, but you can opt in by installing usrmerge | 17:52 |
| mgedmin | another machine was installed from ubuntu gnome 16.04.1 lts and also has separate /usr | 17:53 |
| mgedmin | a cloud VPS from ovh with ubuntu 18.04 lts also has a separate /usr | 17:54 |
| daftykins | i would have to say that trying to give answers from a system with that much history is going to be fraught with errors because you don't know what might have been dragged along with it | 17:54 |
| mgedmin | oh I keep a changelog on every machine | 17:55 |
| daftykins | that doesn't sound practical | 17:57 |
| mgedmin | it's very helpful | 17:59 |
| mgedmin | "how did I deal with the apache 2.2 -> 2.4 transition? oh I can look it up on server X's changelog" | 18:00 |
| daftykins | i don't see such notes giving you a detailed specific answer as to the full change history from one version to the next, since upgrades sometimes take a different path depending on what you have | 18:01 |
| daftykins | a clean install could still feel quite alien to someone that'd just taken upgrade paths | 18:01 |
| mgedmin | maybe? I've done a number of clean installs and even more upgrades, and I feel at home on every system | 18:04 |
| daftykins | alright, well disappearing modules is a new one on me :D | 18:05 |
| mgedmin | to me too! | 18:06 |
| mgedmin | I've been using ubuntu since 4.10, and I've never heard of kernel modules just disappearing | 18:07 |
| mgedmin | debsums -c linux-modules-$(uname -r) | 18:07 |
| tomreyn | usrmerge is in universe in all supported releases - https://packages.ubuntu.com/search?keywords=usrmerge - so IF there is or was a mechanism what would carry out the change, it would have done it without usrmerge. | 18:17 |
| mgedmin | I think it's the installer that uses the new merged /usr layout since about 18.10 or 19.04 | 18:20 |
| mgedmin | docker run --rm ubuntu:bionic ls -l / vs docker run --rm ubuntu:focal ls -l / | 18:21 |
| mgedmin | yeah cosmic vs disco show that it happened in 19.04 | 18:22 |
| tomreyn | *which* installer then? all of them? | 18:24 |
| tomreyn | choose from: subiquity, d-i, ubiquity, calamares, debootstrap, cdebootstrap, and those others i'm forgetting. ;) | 18:25 |
| tomreyn | whatever builds cloud images, too. | 18:26 |
| mgedmin | newer releases don't support d-i, and I don't think deboostrap and friends were ever officially supported? | 18:38 |
| mgedmin | huh, no mention of /usr merge in https://wiki.ubuntu.com/DiscoDingo/ReleaseNotes | 18:39 |
| mgedmin | wow ubuntu originally planned to support merged /usr since quantal! https://wiki.ubuntu.com/FoundationsTeam/Specs/Quantal/UsrMerge | 18:41 |
| mgedmin | and there was an announcement about merged /usr for new installs to ubuntu-devel@ mailing list at the beginning of disco's development | 18:42 |
| mgedmin | debootstrap uses merged /usr by default since 1.0.102: https://wiki.debian.org/UsrMerge | 18:42 |

| oerheks1 | https://www.zdnet.com/article/riaa-blitz-takes-down-18-github-projects-used-for-downloading-youtube-videos/ | 21:51 |
| JPSman | its at the top of ycombinators hacker news | 21:51 |
| oerheks1 | tons of it, and twitter should give trend :-D | 21:51 |
| oerheks1 | now flash is dead... | 21:51 |
| daftykins | what relevance does flash have? | 21:53 |
| jeremy31 | flash gordon? | 21:54 |
| daftykins | Gordon's alive! | 21:56 |
| oerheks1 | flash itself is not important, just in the timeline | 21:56 |
| JPSman | flash was so easy to create animations for though | 21:56 |
| JPSman | I havn't seen something can compare since | 21:57 |
| JPSman | is there some kinda of Macromedia Flash Studio for HTML5? | 21:57 |
| JPSman | nvm | 21:57 |
| JPSman | off topic | 21:57 |
| tomreyn | https://twitter.com/search?q=youtube-dl mirror | 22:01 |
| tomreyn | s/ /%20/g | 22:01 |
| oerheks1 | I think youtube is funny. on Mac and Windows i get ads in between. on ubuntu it is free of ads. | 22:02 |
| oerheks1 | They don't want anyone to share this code: mplayer $(echo -s "http://youtube.com/get_video.php?$(curl $youtube_url | sed -n "/watch_fullscreen/s;.＊\(video_id.\+\)&title.＊;\1;p")&fmt=22") | 22:08 |
| sarnold | omg think of taylor swift before you post that! | 22:10 |
| jeremy31 | She won't get a headache, need a brain for that to happen | 22:11 |
| oerheks1 | taylor swift, i had to bing that. | 22:13 |
| sarnold | raii used one of her songs as justification for the takedown notice | 22:13 |
| tomreyn | https://code.hackerspace.pl/q3k/youtube-dl is the most recent git copy i found | 22:15 |
| tomreyn | (i haven't checked authenticity) | 22:16 |
| sarnold | tomreyn: maybe just purge that package? -boost- packages are (usually? always?) just source code and probably not important for anything at runtime, just the next time sometihng that uses boost is compiled | 23:15 |
| tomreyn | sarnold: okay, will try, thanks | 23:17 |
| tomreyn | i want to go for apt-forktracer next, also, hope this will clarify it | 23:17 |
| sarnold | oh good idea | 23:17 |
| sarnold | that's a useful thing, I never think of it first though :) heh | 23:17 |
| tomreyn | nor does anyone else, documentation on steps needed before release upgrade would certainly help. | 23:20 |
| tomreyn | (we may have discussed this before) | 23:20 |
| sarnold | and most devs never even think of it because we almost never step outside the main archive, never pin things, etc | 23:28 |
| tomreyn | hmm, a lot of (non ubuntu) dev's coming to #ubuntu do habe third party repositories. | 23:46 |
| sarnold | way more than I'd ever expect | 23:47 |
| sarnold | and some folks have ~20 | 23:47 |
| tomreyn | Sbur3 has more :) | 23:49 |
| tomreyn | well collected across three ubuntu releases | 23:49 |
| sarnold | oh my :) | 23:49 |
| tomreyn | it's not that uncommon, really | 23:52 |
| tomreyn | i agree that corporates (whose output you probably see most) will likely be more careful about which third party repositories they activate | 23:54 |
| sarnold | I hope so | 23:55 |
| sarnold | I mean, it's an odd situation ... open source is built on the contribution of thousands of people you'll never meet | 23:55 |
| sarnold | but giving all those people root on your system is a bit strange | 23:55 |
| tomreyn | very much so. i don't think most people are aware that they do so by activating third party repositories. | 23:56 |
| tomreyn | and i don't think anyone but a select few like those hanging around here daily, are aware that you can end up with such 'foreign' 'leftovers' | 23:57 |
| sarnold | yeah, irc is good for learning those kinds of things | 23:58 |
