[00:07] Once20.04 releases, 19.10 support drops? [00:08] 19.10 support will end 20.07, 9 mo [00:32] hi, i have Xubuntu 19.04 installed, but to get metasploit I added the Kali package repository [00:32] hmmmm, that makes a not-ubuntu installation, good luck with that. [00:32] then when i sudo apt update and sudo apt upgrade, it started updating all my xubuntu packages with kali linux packages... when i rebooted it went to a blank black screen with a blinking underscore [00:33] help? [00:33] how do i undo this? [00:33] reinstall xubuntu. [00:33] i have a home directory that i don't want wiped out though [00:33] but take 19.10, that is supported. [00:34] hggdh: The Ubuntu installer will allow you to reinstall while preserving your home directory, even without /home on a separate partition. [00:34] hmmmm: ^^ [00:34] true. [00:34] really? [00:34] should i try to back up with a livecd just in case? [00:35] hmmmm: Backups are always a good idea. [00:35] also, why is this even possible in the first place? [00:35] hmmmm: https://github.com/rapid7/metasploit-framework/wiki/Nightly-Installers [00:35] doesn't it make sense that you'd add alternate repositories to get one piece of software, not everything? [00:35] "if you have no backup of your precious data, it is not important" [00:36] hmmmm: If you add a repository with packages that are newer than the ones you have installed, they will be installed automatically. There are ways to add repositories without that happening, but it is not the default. [00:36] this is ridiculous, it's an apt beginner's trap [00:36] also consider whether there is disk/home encryption [00:37] how could've i anticipated it would destroy my installation [00:37] err, you understand kali messes around with privelidges and apparmor? [00:37] no, did not know that [00:37] it is not ubuntu anymore [00:37] one should run that in a VM, kvm preferrably [00:38] vbox is too easy to escape [00:38] grinn [00:39] or just pick an old laptop [01:17] hey guys, how do i reinstall ubuntu if it was previously installed with a single LVM partition? [01:18] i am in the installer, i selected "Something else", and it gives me the screen where you manually edit the partitions. /dev/mapper/vgxubuntu-root i set the mount point to / with the same ext4 fs, unselected "Format?", didn't need to change anything for the swap partition, and it doesn't give me any options for /dev/sda1 [01:19] ...is this right? [01:20] well i just went for it, the installer gave a warning that the directory structure won't be deleted, so i guess that's reassuring [01:23] hmmmm: Sorry for the late answer, but that seems right. Do you have a UEFI based machine, and did /dev/sda1 end up being a fat32 partition mounted at /boot/efi/ ? [01:23] i don't remember what i put for the bootloader type in the original installation [01:23] it didn't say anything for partition type in //dev/sda1 - no details [01:25] hmmmm: Did you choose the option that lets you run other programs while the installer is running? If so, can you open a terminal and pastebin the output of "mount"? That should hopefully clear up how the partitions are being used. Either way, you probably have things setup correctly. [01:27] https://nYiWicvc [01:27] oops [01:27] https://pastebin.com/nYiWicvc [01:28] oh this doesn't sound good... "Error restoring installed applications - an error occured while restoring previously-installed applications. The installation will continue, but you may have to manually reinstall some applications after the computer reboots" - actually that doesn't sound terrible [01:28] oh dammit i forgot to backup the tftp server config [01:30] but other than that, we're back! [01:32] hmmmm: Have you successfully rebooted? I don't see any EFI System Partition mounted. Is your computer configured to boot via UEFI? === tds1 is now known as tds [01:33] oh, no, EFI was disabled [01:33] hmmmm: That error likely refers to applications you had installed from Kali's repositories. [01:34] and yes, i have successfully rebooted [01:34] hmmmm: Great, then sda1 is probably being used as a BIOS Boot Parititon (which has no filesystem, and thus doesn't get mounted). [01:37] i think i'm mostly back on track now [01:37] thanks [01:37] hmmmm: You're welcome. === tehaugmenter is now known as augz [01:49] in a dir -l ls drwxrwxrwx+ 1002 65534 users 20480 Mar 30 13:37 - what does the 1002 and 65534 mean? === zbenjamin is now known as Guest23392 === zbenjamin_ is now known as zbenjamin [02:01] uid and gid [02:02] al_nz1, number of links to the file (1002 is a lot, what is going on) and uid of owner (numeric because apparently 65534 isn't used in your /etc/passwd) [02:02] hmm ignore my answer [02:02] rfm: thanks. Re the link [02:03] links - its a file structure created by a NAS - has lots of sub dirs [02:04] al_nz1, ok, all those subdirs have the '..' link pointing back up. (65534 is usually "nobody", btw) [02:05] what do you mean by .. ? as in when you cdup with cd ../ ? [02:06] al_nz1, yes, every directory contains a entry named ".." which is a link to the parent. That's why "cd .." takes you up a level... [02:11] so the ".." is related to the 1002? [02:13] al_nz1, yes, presumably the directory has 1001 subdirectories, each with its .. link and the parent of the directory you are listing has a link down into it, making 1002 [02:20] Thanks rfm [02:32] rfm: is 0 = root? [02:32] in the context of chown 65534:0 [02:53] al_nz1: no it is not [02:53] al_nz1: the second parameter is the group ID [02:56] GoneViral:nA UID or GID of 0 is root. [02:56] al_nz1: ^^ [02:57] al_nz1: ah yes. [02:57] isn't it a bit abnormal for nobody:root permissions? [02:59] (sorry for the confusion, also.

[06:53] hmm [06:54] YogaRolf: and do you know if your system 'sees ' it? like what does lspci give? [06:54] not sure how do i check what i have [06:54] 2sec [06:54] try opening a terminal and typing 'lspci' [06:55] ok. i am just waiting for Lutris first installing [06:56] I am connected through phone atm [06:56] YogaRolf: or maybe inxi -n [06:56] YogaRolf: 'inxi -n [06:57] YogaRolf: and have you checked to see if any drivers are suggested by mint?.... sorry 2 questions in a quick row... take your time [06:57] realtek [06:58] But i dont have mint, I have UBuntu though [06:59] YogaRolf: sorry same thing underneath...so it will work too [06:59] YogaRolf: wrong channel but the info is the same... =) [06:59] thanks.oki:) ITs updating something now autmatic maybe works after [08:00] Thanks.

Hmm === remy^ is now known as Ad === Ad is now known as Ad_Patat === Ad_Patat is now known as Pad_Patat === Pad_Patat is now known as Pat_Patat [08:21] 7th time or more that I try to install / reinstall linux mint on my MSI comp. and I keep getting to the initramfs console on boot, and when exiting it says it cannot find the UUID of the / partition, even though the UUID mentioned is 1-to-1 what is in the /etc/fstab file... [08:21] I am using an /boot/efi partition, or at least I'm trying to do so [08:21] Mint has it's own support channel, #linuxmint-help on irc.spotchat.org [08:21] Is hibernate disabled by default on 18.04? Then why could I do sudo systemctl hibernate? (but it didn't work on poweron) [08:22] Ben64 pretty dead channel. I'd like to believe people in the Ubuntu channel might be familiar with this "UUID does not exist" error [08:23] This channel is only for Ubuntu issues [08:24] linux mint runs on ubuntu, no? It says on boot that it runs a 5.0.0.32 image [08:24] It isn't Ubuntu, it's based on Ubuntu [08:24] Bomber4Chats: Ben64 just explained you we cant support it [08:25] ¯\(°_o)/¯ So I don't have linux mint, I have Ubuntu 5.0.0.32 ^_^' [08:25] k, nm. hoping someone will be willing to help in private [08:27] 5.0.0.32 sounds like a Linux kernel version, this will be across all distros, Ubuntu, Debian, Mint, Fedora... this is specifically Ubuntu only support, because Linux Mint is similar enough to lull you into a sense of false security, then confuse you with a difference. [08:27] but the kernel boots the same across all distros, doesn't it? [08:27] just the boot sequence [08:28] yes but this is support for Ubuntu, similar to how you can't take your Vauxhall to a Ford garage even though they both use gasoline === PowerTower_121 is now known as PowerTower_120 [09:16] Client: HexChat 2.14.3 • OS: ArchLinux • CPU: AMD Ryzen 3 2200G with Radeon Vega Graphics (3,49GHz) • Memory: Physical: 3,8 GiB Total (2,8 GiB Free) Swap: 8,4 GiB Total (8,4 GiB Free) • Storage: 11,9 GB / 24,2 GB (12,3 GB Free) • VGA: InnoTek Systemberatung GmbH VirtualBox Graphics Adapter @ Intel Corporation 440FX - 82441FX PMC [Natoma] • Uptime: 1h 41m 35s [09:17] sorry, didn't meant to send this [09:48] question about cron [09:48] is this correct?

I have a small crisis here. My PC boot. It shows a message of "recovering journal". What can I do?? [10:07] My PC won't boot now. I'm in root shell from the recovery mode [10:08] I tried a fsck -f / but it says "/dev/sda5 is already mounted" [10:08] What can I do?? [10:12] you can't fsck a device that's mounted [10:14] Does that mean I have to use a live CD? === Alina-malina_ is now known as Alina-malina [10:15] ok Ben64 [10:15] If you have a an issue at boot that need fsck I would use a live image and while booting the live image I think you hold Esc to get the splash screen you can select Check disks [10:16] Either that or you can just boot the live image and use gparted to run a fsck [10:16] I will do that [10:16] Let's see [10:18] Running [10:19] If you use gparted make sure it's not mounted and right click then Check [10:20] If it was mounted, I wouldn't be able to check it, no? [10:21] I think it should tell you and you have to force it, you shouldn't fsck a mounted device you'll cause data loss [10:21] https://paste.pics/fcdcef65522adeaebd862c7629e403e1 [10:21] It's green [10:23] This is what I'm getting now [10:23] https://paste.pics/c2e4288d686c491eb66fae1982cb9237 [10:23] When I boot [10:23] The message about the journal is gone, but it's still not booting [10:24] just wait a little [10:25] Ok. I will [10:25] 15 minutes should suffice? [10:26] I was thinking more like a couple of minutes. what does it display now? [10:26] Still the same... [10:31] No change === Clippy is now known as Birosso [10:34] did gparted complete on the correct drive? [10:35] There is only one [10:39] You could try to fsck again with the live image, always make sure its not mounted first. You could mount the drive to see if your stuff it there and maybe back it up if that's of concern. After that you could try to manually repair boot or reinstall Ubuntu over the top keeping your documents. [10:43] I have Timeshift installed. Maybe doing a restore from yesterday could help?? [10:48] sixwheeledbeast: isn't gparted going fsdk? [10:50] gparted should have done fsck with the check option? yo could run fsck from a terminal manually if you want [10:51] Can I install some package from a private repo (specifically https://jitsi.org/downloads/) without actually adding the repo to my sources and trusting their keys, etc.? [10:51] I wouldn't mind generally, but I'd like to avoid querying these repos every time I apt update [10:52] sixwheeledbeast: could you confirm me which command exactly should I run? [10:55] fsck and then the partition [10:55] I mean the exact commands [10:56] For the first, I used "fsck -f /dev/sda5". Is that correct? [10:56] I have no idea where your partitions are but if you believe its sda5 then "sudo fsck /dev/sda5" [10:57] Yeah, I did that.

[11:52] Gemosa: alternatively you could do a standard installation by writing the installer to an usb stick and booting off that. but you may end up without vendor specific customizations, software and drivers then.

[13:52] pragmaticenigma: OpenSSH enables usage of U2F security keys with certificate authentication [13:53] Dwarf: Do you need client support of that feature, or server level? [13:54] It seems that the server also needs to be version >=8.2 in order to support it, though I couldn't find any documentation on this [13:55] Dwarf: It sounds like something that both client and server would need to support, correct. I'm trying to understand your usage case, are you trying to connect somewhere, or just looking to harden your personal systems? [13:57] My client is 8.2, my Ubuntu server is stuck on whatever Bionic ships [13:58] Dwarf: Bionic is 7.6, it's something I would caution against trying to upgrade as it may break other things on your system [13:59] A shame. Guess I'll have to wait for the next LTS then [13:59] Dwarf: Eoan (19.10) has 8.0, and the upcoming Focal (20.04) will only go to 8.1 for now. I suspect that the feature your seeking is accompanied by other buggy features which is why Ubuntu is staying a little behind for now [14:00] Aw [14:01] Dwarf: you might want to look into the documentation... it's possible the feature has been backported [14:01] at least in Ubuntu versions support the 8.x series [14:06] good morning/afternoon/evening [14:06] What Ubuntu-based distributions do people recommend for young kids?

You might have some luck using a different flavor such as Xubuntu, or Lubuntu. Which do have lower system requirements. [14:59] malekmaroc7: try lubuntu or xubuntu [15:00] Do Lubuntu and Xubuntu have the same features like Ubuntu?

[16:06] yossarianuk: there's this https://www.omgubuntu.co.uk/2019/11/ubuntu-20-04-daily-builds-available [16:06] or do I have to wait for the beta .iso to come out ? [16:08] MonkeyDust: thanks - but I mean after 20.04 stable is out would it stick to 20.04 or as i'm in the dev branch would i then start to be on the 20.10 branch [16:08] i want to just use the 20.04 branch ... [16:08] I believe the beta (due out in days) would stick to the 20.04 branch [16:19] yossarianuk: once you are on the dev branch, you stay on the dev branch unless you manually switch over to either the LTS or regular release cycle in the package manager. Further questions should really go to #ubuntu+1 [16:20] yossarianuk: anything called "focal" will stay focal (20.04), but you might need to ensure the upgrade path is set to 'lts', not 'normal', in /etc/update-manager/release-upgrades [16:20] pragmaticenigma: ok thanks [16:22] pragmaticenigma: I'm embarrassed to admit this but I have two machines side-by-side and I checked the ethernet cable on the wrong one. You were correct -- it wasn't fully plugged in. :| [16:23] hi. What is the notification daemon used in ubuntu? [16:24] mustmodify: it happens to the best of us... I have a lot of bad cables ends where the cable works fine, just the retainer clip no longer works [16:24] damoreno: You might need to be more specific.. what exactly are you trying to do? [16:24] pragmaticenigma: just wondering what is ubuntu using. notify-osd? notification-daemon...? [16:27] damoreno: There are multitude of ways notifications can be sent. So what you see will help in narrowing down what you're targeting === skookum4 is now known as skookum === lestac is now known as lestac_hra === Newfangled is now known as Dallin === Dallin is now known as Newfangled [17:06] is here an okay place to chat about 20.04? [17:07] psymin: For general chat please use #ubuntu-offtopic. For support of Focal, please use #ubuntu+1 [17:30] hi all [17:30] how can I install python 3.7 in focal fossa? [17:30] how can I install python 3.7 in focal fossa? [17:30] we have a rather hard dependency on that python version (with vtk) and we'd rather keep python 3.7 than patch vtk [17:30] isemenov: #ubuntu+1 for 20.04 support please [17:33] don't downgrade, fix your code. https://launchpad.net/ubuntu/focal/+source/python3.8 [17:34] oerheks: its not my code, it's a whole huge library [17:34] and sometimes stability is best [17:35] wel, 3.8 is stable, and 20.04 is lts. [17:37] oerheks: I understand that, sure. by stability I refer to the stability of our software project which is know to work fine with the combo of vtk 8.2 + py 3.7 [17:37] *known [17:37] what is the difference between ubuntu 18.04 and ubuntu 19.10? [17:38] 19.10 has later software and is not lts [17:39] oh. i have downloaded 19.10. is it ok to install it for now? === themacproguy is now known as Zachary_DuBois [17:39] sure, but be prepared to upgrade in april when 20.04 is released [17:40] isemenov: Python2.7 is no longer supported. The Python group has recommended that everyone stop using it as soon as possible. What ever the library you are using, it sounds like it hasn't been updated or worked on in a long time. I'd be looking for a newer solution. [17:40] ducasse, definitely i will. thanks! [17:42] Palmar: *3*.7 ) [17:42] er, sorry Palmar. I meant to notify pragmaticenigma [17:42] Palmar: my question was about three dot seven [17:43] isemenov: apologies, I didn't catch the update [17:43] yeah, no problem. do you think it's possible? [17:43] isemenov: code written for 3.7 should work fine under 3.8 [17:43] pragmaticenigma: https://gitlab.kitware.com/vtk/vtk/issues/17670 [17:44] C++ bindings updated ever so slightly [17:45] isemenov: They released a patch, I would investigate the issue from that angle. It is possible to install 3.7 along side 3.8 in Ubuntu using virtualenv (which is what you should be using) [17:48] pragmaticenigma: at the moment we install python using apt-get, what are the + and - of using virtualenv to do that? [17:48] can such an installation be made system-wide, protected by root access rights? [17:49] virtualenv: environment prevents your python application requirements from interfering with the system tools that rely on python [18:02] Ubuntu 19.10 I get a segfault of gnome initial setup [18:02] kern.log:Mar 30 16:10:52 lenlin kernel: [ 115.495273] gnome-initial-s[1937]: segfault at 0 ip 00007fe39c0b5572 sp 00007ffc934bed08 error 4 in libc-2.30.so[7fe39c02d000+178000] [18:06] https://paste.ubuntu.com/p/3fcGVZmjdy/ [18:09] Help! Something very strange is going on with my Ubuntu Server installation, and I simply cannot find out what it is. Roughly every 2 days or so, I loose the ability to host services on port 443. If I restart the server, everything is fine again. What could possible be causing this issue? [18:10] I run nc -l 443 on the server, and nc -v 443 on another machine to test the issue. [18:11] chucara: Are all system updates and patches applied? [18:11] pragmaticenigma: Yup [18:12] pragmaticenigma: It's a <7 days old installation of 18.04 LTS and I've applied all patches between then. [18:12] have you check the system logs... check systemctl status apache2.service ? [18:12] chucara: the first one needs sudo nc -l 443 ... (just tried it between two systems [18:13] What do you mean by losing the ability to host services, does something normally run on 443 and stops? [18:13] pavlos: Ah sorry skipped the sudo. I can succesfully run the command after a restart and see messages across the machines. [18:13] Ben64: First symptom I see is my traefik reverse proxy stops responding and shuts down. [18:14] I get a message: time="2020-03-29T20:29:47Z" level=error msg="close tcp [::]:443: use of closed network connection" entryPointName=websecure If that provides a hint. [18:14] ^ From the traefik logs [18:15] Can it be a hardware related issue? (power save state or something?) [18:15] chucara: that's a symptom... but doesn't help find the cause... what does your web server logs say? [18:15] pragmaticenigma: Not sure I follow.. Which web server? [18:16] chucara: whatever webserver your running on port 443? I don't know your configuration, you need to provide us more details of yor configuration... what roles things/servers play, what connects to what, etc [18:17] pragmaticenigma: Traefik is running on port 443 and redirects traffic into various docker containers. But their logs are empty as no traffic reaches even traefik on the system when this happens. I can't even netcat on said port. [18:18] I've also tried with a simple python web host - same issue. [18:18] have you tried using netstat to see if anything has the port open when you cannot connect to it? [18:19] pragmaticenigma: Yes, when I stop the docker container for traefik (or stop the docker service completely), the port is not listed in netstat. [18:20] Meanwhile, when I access the port via localhost or 127.0.0.1, everything works as expected. [18:21] I'm all out of ideas, unless it is my motherboard reserving the port for ASUS Control Center (pseudo IPMI solution). But I don't know how to check [18:21] so a docker container is redirecting to other docker containers? [18:21] pragmaticenigma: Yes [18:21] fyi all: https://docs.traefik.io/ [18:21] This is sounding more like an issue to bring up in a docker forum [18:22] pragmaticenigma: It's not a docker issue. I cannot netcat into the machine on this particular port when the docker service isn't running at all. [18:23] At least I cannot see how it can be... [18:24] if the/a docker instance crashes anything is possible [18:24] Ubuntu 19.10 Just after login, I get a segfault of gnome initial setup [18:24] kern.log:Mar 30 16:10:52 lenlin kernel: [ 115.495273] gnome-initial-s[1937]: segfault at 0 ip 00007fe39c0b5572 sp 00007ffc934bed08 error 4 in libc-2.30.so[7fe39c02d000+178000] [18:24] https://paste.ubuntu.com/p/3fcGVZmjdy/ [18:25] session: x11 [18:25] How would I be able to determine if that were the case? Shouldn't the operating system know whether a network interface was down somehow? [18:25] The interface is not as all other ports are accessible, and I can ssh into the machine. [18:27] !patience | frank [18:27] frank: 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/ [18:27] chucara: which is why I'm suggesting that this might be a docker specific issue and a docker forum may provide better help in resolving this issue. [18:28] pragmaticenigma: I went there originally, and they claim it to be a OS issue :D I'm looking for ways to find more information. [18:29] pragmaticenigma, my apologies, the repitition of my request was corrected slightly so that it was set in a more logical order. I had no intention of repeating the issue because I would not be heard. [18:29] Alternatively whether it is hardware related. This is a brand new server. [18:30] I'm not saying docker isn't the cause, but at least if I knew exactly what it was doing, I'd have an easier time raising an issue over there. [18:30] I'm getting one issue after another, first name resolution didn't work anymore, now files which should exist appear to be replaced by broken symlinks, e.g. "/etc/mtab -> ../proc/self/mounts" I;m guessing I'm at the point again where I simply have to reboot [18:30] frank: is it missing zh_CN.utf-8 ? [18:30] /tmp seems to be replaced by a mount from loop0 [18:31] pavlos, yes and lot's of other locales, but I guess this caused by the crash rather than the other way around [18:33] seems the original issue was caused by bind mounting / to /mnt and then mounting something over it (because I couldn't unmount /mnt as it was in use by everything using the rootfs) [18:33] Celmor[m]: Unless someone is actively helping, please don't monolouge your way through the situation [18:33] frank: does journalctl -xe give you more info? [18:35] pragmaticenigma: I merely presented my problem and what I think the issue is which I just now found out. I thought it's frowned upon to disappear from a chat once a solution is found without telling anyone [18:35] but as you wish, I'm gonna leave [18:36] pavlos, I'll try, but it has been rebooted since that error. This error occurred prior to the greeter and I found that he could not continue without rebooting the machine. [18:37] pavlos, besides, it crashed so hard that it left a core dump [18:37] chucara: I don't know docker well enough. Someone in #ubuntu-server might be more knowledgeable on that aspect and interplay with Ubuntu [18:38] frank: I dont know how to analyze a coredump but it may give you ideas ... [18:38] pavlos, I am speaking on behalf of frank, I am his son and a sysadmin in daily life. Still, I am no kernel debugger ;-) [18:39] pragmaticenigma: Ok,well thanks for your help :) [18:39] frank: maybe someone else can help ... [18:40]
