[00:02] Duckle: had to go afk, sorry.. still with you though.. I had a similar 'udev + user executed script' need for my semi-broken touchpad.. If you're willing to wait 10 minutes I'll make a paste adapted to your setup.. it uses a systemd service file instead of sudo in the udev rule, based on http://jasonwryan.com/blog/2014/01/20/udev/ [00:03] glitsj16: More than willing to wait, thanks a lot [00:04] Duckle: okay, no problem, dusting things off.. I'll report back here in a few [00:04] thanks man [00:07] Oh FFS. I'd have to compile my own kernel to do this. The hell is wrong with amd drivers. [00:16] Duckle: https://gist.github.com/glitsj16/000053cb1d6d9e5169c22ed1ccc4404d .. take a look at it, ask if something isn't clear etc.. [00:17] I'm using lubuntu and I can't disable my touchpad. I've tried 2 or 3 different apps, and a couple of terminal commands, but to no avail. [00:19] Duckle: You'll need to create that extra script I called /etc/mikkel/ios, chmod +x it and adapt the naming to whatever you prefer ofcourse [00:19] I'll give it a go. thanks :) [00:26] glitsj16: Do I have to reload the units ? [00:27] Duckle: 'sudo systemctl daemon-reload' should be all it takes.. the udev rule triggers the /etc/mikkel/ios script on both adding/removing your phone and runs the mount/unmount script .. that's the logic [00:28] Duckle: so you'll need to re-plug your phone [00:31] hmm, that doens't work. not even manually :/ [00:32] hmm for some reason that asks for my password [00:33] Maybe change "RequiresMountsFor" from /home/ to /home/mikkel ? [00:33] glitsj16: ^ [00:33] Duckle: let's go over it.. what happens when your phone is plugged in and you run 'sudo systemctl start ios-mount'? [00:34] ehm unit not found. odd [00:34] I did reload, lets see if I misspelled something [00:35] Duckle: wait, I made a mistake in the paste, apologies.. you need to caal the systemd scripts .service [00:35] right figured that out :P [00:36] I though I'd forgotten the extension. Hell we both did :P [00:36] you bumped into the worst helper possible I'm afraid :p [00:36] hah, ok well, now running that service does nothing [00:36] weird [00:37] well, we should be able to sort things out, sudo asking for a password we can deal with that [00:37] yeah that's because I derped and forgot that ofc systemctl needs a pass [00:37] it'll change users according to the unitfile === bazhang_ is now known as bazhang [00:38] Duckle: for testing, to check if the scripts get reached, maybe touch a file is your user dir somewhere in your ios_script [00:39] *in [00:40] no touchy [00:41] danm [00:41] /etc/mikkel/ios is executable right? [00:41] it's like the udev never runs [00:41] yea [00:42] when that didn't work I tried bypassing that file and just called systemctl start directly from the rule [00:42] I figure that'd be fine right? [00:43] yes it should [00:45] if the udev rule is still there it might interfer with manually running the commands, maybe try to uncomment both lines for now and replug your phone again.. sudo /etc/mikkel/ios mount [00:47] Hello hello...I seem to have done something dumb and would like some help cleaning up any potential messes :) [00:48] Monkeyhuouse: So, What did you do ? And what is the result ? [00:48] Duckle: ow you tried systemctl start .. in the udev rule? That doesn't work, although I don't know why to be honest [00:49] Well I have a modest laptop with a plain latest ubuntu (16.04?) that I just use as an extra interface for online stuff, text editing, and the occasional linux learning. I run updates every week. As far as I know, I don't do anything goofy or detrimental to the machine: poking around with it and junk. But for some reason, it offered a partial upgrade. [00:50] So I took it, thinking it wouldn't be any harm, and better than nothing. But now as I read up about it, it's apparently a bad thing to do! :( [00:50] After I install an i386 package with multiarch, how do I use it if I have the 64-bit version installed? [00:50] Hello, can I ask a question pelase [00:50] So I just want to know what to do to undo any potential damage of a partial upgrade. Could I roll back to my last backup or something? I've never had to do this before, Bashing-om [00:51] glitsj16: Progress. aparrently ifuse is not found [00:51] Duckle: odd, I assumed if your script works from terminal that would be already ok [00:51] a lot of the progams are locally compiled due to it being a new fix [00:52] I have bashrc append that folder to the path, but I guess systemd works with a different env [00:52] Excuse me, I'm so paranoiac about this, I'm so scared that my ubuntu system has been hacked, can someone help me please? [00:53] Duckle: that makes sense yes, you can add 'Environment=...' lines to the systemd units [00:53] I'll just export the paths and such at the start of the script [00:53] see if that works [00:53] Monkeyhuouse: What is done is done . No going back -- no re-do . We move forward . ' what results ' sudo apt update ; sudo apt full-upgrade ; sudo apt -f install ' ? [00:53] I'm using lubuntu and I can't disable my touchpad. I've tried 2 or 3 different apps, and a couple of terminal commands, but to no avail. [00:53] so what should I do? [00:55] Okay, Bashing-om: Did them all, a couple of things were 'automatically installed and no longer required', and otherwise all packages are up to date [00:56] Excuse me, can someone help me to know if my laptop is being remotely controled please ! :( [00:56] you could check /etc/apt/history.log [00:57] plaindave: have you tried xinput or synclient commands yet? [00:57] yeah, synclient worked once but it doesn't work now [00:57] i'm right now trying xinput [00:58] glitsj16: I think I'm going to give up on it for now [00:58] it's 03:00 here [00:59] Can you guys see my messages? [00:59] Duckle: I completely understand, may be wiser to look at it again with a fresh pair of eyes later, sorry I helped 'in-reverse' hehe [00:59] I can, dezde. I don't know how to help, though (I'm here to ask a question, too) [00:59] Oki thank you [00:59] heh It makes no sense glitsj16. I hope it does tomorrow :P [01:00] plaindave: determine the id number of your touchpad via 'xinput --list' and 'xinput --disable xx' === Mittens is now known as MittensAFK [01:00] dedze: hang on one sec [01:01] Duckle: get a good horizontal rest, see you around [01:01] glitsj16, yeah, i just tried that, but it didn't work [01:01] Hope you saw my response, Bashing-om ? [01:01] dedze: run the following in terminal (without quotes) "sudo apt install -y chkrootkit rkhunter && sudo chkrootkit && sudo rkhunter --update && sudo rkhunter --checkall -sk" [01:01] plaindave: is your touchpad listed in xinput at all? [01:01] and go to pastebin.com and copypaste the whole output to that and say the link [01:01] yes r3muxd thank you [01:01] ok [01:01] glitsj16, yeah, it's number 14 [01:02] does anyone know how to run a version of a multiarch program if 2 architectures are installed? === MittensAFK is now known as Servant [01:02] plaindave: any return from the command 'xinput --disable 14' ? [01:02] Monkeyhuouse: Then -f install returned a bunch of zeros .. yes ? Now does ' sudo dpkg -C ' just return to a prompt ? [01:02] Hi! I think I have screwed up my Ubuntu drive. When I boot my laptop, it asks for the password to /dev/sda3. Once I enter it, the computer is stuck and nothing happens anymore. I booted from a LiveUSB of Ubuntu. I unlocked my crypted partition, compiled the latest e2fsck, and ran it. It says everything is clean. I think what damaged my install is that I was backing up a Wii game, and I pressed the wrong button in the program that was do [01:02] to wbfs... The system was running fine until I had to reboot. What now? [01:03] glitsj16, no return text, no [01:03] it tried to convert `/` to wbfs* [01:03] have you tried pressing enter? i'm pretty sure your password won't appear at the prompt [01:03] oh [01:03] that will probably ruin things [01:03] try holding shift, hit e, and go to the end of the linux line and type emergency [01:03] hfp: you compiled e2fsck yourself? why? [01:04] plaindave: I assume you've already tried 'synclient TouchpadOff=1'? [01:04] hfp: what is wbfs? [01:04] glitsj16, yeah, i just did again, but it doesn't work either [01:04] maybe a chain saw will do it :) [01:04] Bashing-om : Yes [01:04] wbfs is a filesystem for wii backups [01:04] hfp: okay, i found wbfs on wikipedia [01:05] No text or anything [01:05] legally obtained, of course [01:05] plaindave: looks like there's a setting in lubuntu overruling things, lol, the chainsaw yes that will work [01:05] tomreyn: because it said "/dev/mapper/ubuntu--vg-root has unsupported feature(s): metadata_csum; get a newer e2fsck!" [01:05] Monkeyhuouse: Should then have no issues :) . Package manager is in a happy state . === Servant is now known as MittensAFK [01:05] glitsj16, i bet you're right [01:06] r3muxd: it is indeed, it's a program so I can transfer my Wii discs to images. But there is an option to export them to a wbfs formatted drive... Not sure why it would target `/` by default but here we are. [01:06] try emergency mode [01:06] hfp: so the liveusb you booted from is older than the system you have installed? [01:06] then run "df -h" [01:06] tomreyn: yeah, it's 16.04 and I borked 17.04 [01:07] Excuse me r3muxd, should i copy and paste all the content of the terminal? [01:07] no [01:07] please go to pastebin.com [01:07] and paste it there, and hit paste [01:07] then tell us the url [01:07] or actually paste.ubuntu.co [01:07] Bashing-om : Awesome! Last question then: What should I do to correct whatever issue it was that necessitated the partial upgrade to begin with? [01:07] or actually paste.ubuntu.com [01:07] r3muxd: emergency mode + df -h is for me or someone else? [01:07] you [01:07] got it [01:07] hfp: i suggest you create a 17.04 bootable usb stick, boot off that,unlock your encrypted disk, then run fsck on that again. [01:08] my bet is that is that systemd hangs because there's no space on root [01:08] glitsj16, hey, thanks for trying. gotta go. [01:08] if you had your root partition encrypted, then get ready to chroot [01:08] Monkeyhuouse: Long good read about partial upgrades : https://ubuntuforums.org/showthread.php?t=1859240 . [01:09] hfp: you need to force the fsck then (while the file system is not mounted), otherwise it may not detect it as being corrupt [01:09] Oh I have to register? Aww.. [01:09] plaindave: no prob [01:09] Is there a public place to read that, Bashing-om? [01:10] alright let me try that, i'm on the broken machine now, I'll reboot [01:10] hfp_: i assume you just got disconnected. see irclogs.ubuntu.com for log. [01:10] so how can i use an i386 binary if i have both the i386 and amd64 binaries installed? [01:10] tomreyn: thanks [01:10] ok, just secondary computer, got it [01:11] Monkeyhuouse: Been too long - since I jouned the forum , but I am surprised that one has to register just to read . [01:11] dedze? [01:11] r3muxd: I think it's good: http://paste.ubuntu.com/25202042/ [01:12] did it get cut off? [01:12] anyone here develop windows apps on ubuntu's bash for windows? [01:12] Monkeyhuouse: Lemme log out of the forum .. and see what I can see . [01:12] Cut off? [01:12] cause i can't find windows.h [01:12] try sudo rkhunter --checkall -sk [01:12] Yes [01:12] there's no output from that command in the paste.ubuntu.com [01:12] ayjay_t: please /join #ubuntu-on-windows for that [01:13] thanks tomreyn [01:13] Oh shit there is a warning in red :'( [01:14] what is the warning? [01:14] Aloha, I need to custumize an ubuntu install dvd for it to boot a laptop with a custom set of programs. What is my weapon of choice? or what is my google term? [01:15] r3muxd: here is the paste : http://paste.ubuntu.com/25202060/ [01:16] /usr/bin/lwp-request [ Warning ] [01:16] This line :'( [01:16] dedze: should the system user 'ussop' exist there? is it legitimate? [01:16] what is the output of "file /usr/bin/lwp-request"? [01:17] ussop is my username [01:17] I think or the name of the computer [01:17] dedze: okay, the other thing to look into is 'Searching for Linux/Ebury - Operation Windigo ssh... Possible Linux/Ebury - Operation Windigo installetd' [01:17] I had to pick 3 different names while installing and i picked, monkey d luffy, roronoa zoro and ussop @r3muxd [01:17] some: https://help.ubuntu.com/community/LiveCDCustomization and https://help.ubuntu.com/community/InstallCDCustomization should get you started [01:18] How do I do this tomreyn ? [01:18] r3muxd by output you mean warning? [01:19] ok, so the operation windigo is a false positive [01:19] yes [01:19] dedze: i need to lookup how ebury works, forgot the details [01:19] glitsj16: Thank :) [01:19] run "file /usr/bin/lwp-request" [01:19] I write this in the terminal? [01:19] yes [01:19] file /usr/bin/lwp-request [01:19] ussop@Roronoa-Zoro:~$ file /usr/bin/lwp-request /usr/bin/lwp-request: a /usr/bin/perl -w script, ASCII text executable [01:20] ok, so can you put the output of "cat /usr/bin/lwp-request" into a paste? [01:20] Monkeyhuouse: I have a work-a-round to access the forum . working on it to get it exact for you . [01:21] it is here r3muxd http://paste.ubuntu.com/25202090/ [01:22] r3muxd, tomreyn: This is the error after I decrypt the drive http://imgur.com/a/UFhNV [01:22] ok, that just seems to be a shell script. you're good [01:22] dedze: sudo apt-get update && sudo apt-get install debsums && sudo debsums --all --changed | nc termbin.com 9999 | xargs echo 'Please paste this URL to the channel: ' [01:23] hfp_: https://askubuntu.com/a/752282 [01:23] Yes tomreyn [01:23] hfp_: i dont see an error there [01:25] tomreyn: is there a space between echo and '? [01:25] dedze: yes [01:25] Thank you [01:25] tomreyn: You don't see the picture I took of the display? [01:26] tomreyn: do I need to also write 'Please paste this URL to the channel: '?? I'm sorry if it's a dumb question [01:26] just paste the url it says to [01:28] hfp_: i do, but these warnings are normal if you have / on FDE [01:28] hmmm that doesn't look good... If I unlock /dev/sda3 (the data partition) and then look at where it's mounted (/tmp/data), it's empty... Did it wipe my `/`? [01:28] dedze: actually just do this and report the URL here: sudo apt-get update && sudo apt-get install debsums && sudo debsums --all --changed | nc termbin.com 9999 [01:28] your data partition would be / [01:28] tomreyn: I thnk it didnt work [01:28] did it have a url? [01:28] dedze: my bad, sorry, see above [01:29] r3muxd: I did cryptsetup luksOpen etc for /dev/sda3 and then mounted it at /tmp/data on the LiveUSB system. If I `ll /tmp/data`, it's empty [01:30] um. [01:30] hfp_: if you did cryptsetup on /dev/sda3 then to mount ther file system on it you would need to mount /dev/mapper/... [01:30] it *may* have been like a "rm -rf /*" [01:31] try ls -la /tmp/data? [01:31] tomreyn: http://paste.ubuntu.com/25202142/ I am not sure if it's finished but it's not doing anything more [01:31] I did `sudo cryptsetup luksOpen /dev/sda3 data` then I did `mkdir /tmp/data; sudo mount /dev/mapper/data /tmp/data` [01:32] and now if I `ll /tmp/data` there is nothing there... [01:32] but my system would have exploded if I rm -rf / while it was running, no? [01:32] hfp_: okasy, sounds correct. maybe unmount it again and e2fsck -f /dev/mapper/data [01:33] probably [01:33] unless it hit something like /dev/sda [01:33] did you terminate it partway through or something? [01:33] Me? No [01:34] Oh the process is still running it says when I try to close the terminal but it seems stuck [01:35] dedze:okay, run this now: sudo apt-get install pastebinit; sudo debsums --all --changed 2>&1 | pastebinit - [01:35] no I think it didn't mount altogether... If I try to umount /tmp/data it says not mounted [01:35] and mounting /dev/mapper/data returns unknown filesystem LVM2_member [01:35] that scared me for a sec... getting / wiped is no fun [01:36] hfp_: so you actually have an LVM2 layer on top of the crypto layver [01:36] Oh r3muxd quitted, can I send him a message that he can see when he will rejoin? [01:36] hfp_: sudo lvmdiskscan [01:37] dedze, use memoserv [01:37] dedze, /msg memoserv help [01:39] Thank you bazhang [01:39] tomreyn: http://termbin.com/lz63 [01:40] tomreyn: it is stuck too [01:41] hfp_: /dev/ubuntu-vg/root will contain your root file system (on top of an LVM2 and a dmcrypt-luks layer and a partition) [01:41] dedze: where? [01:42] dedze:debsums can take a while especially with slow storage === some is now known as tharkun [01:42] tomreyn: I don't understand how to access the partition though. /dev/ubuntu-vg/root isn't a normal directory, it points to ../dm-1 which itself is a special dir [01:42] tomreyn: Setting up pastebinit (1.5-1) ... here but I the [01:42] I mean not a dir either [01:43] hfp_: unless you mean to wipe or copy it, just treat it like a partition you can mount [01:43] Arg I typed something in the terminal by mistake and now its stopped for good i will retype the command [01:43] tomreyn: ok so I have to mount /dev/ubuntu-vg/root somewhere to see my files and run fsck on it? [01:43] hfp: ...or a partition containing a file system which you want to e2fsck (while it's not mounted) [01:44] tomreyn what are we trying to do exactly? [01:44] hfp_: you would have to mount it somewhere to inspect its contents, right. but i'd e2fsck -f it before you mount it. [01:45] tomreyn: alright fsck -f found a few errors, I fixed them, a second run finds no errors... Is it safe to attempt to mount it now [01:47] dedze: debsums is a utility which checks, for all installed packages, whether the files which came with it have been modified (by you or a potential intruder). [01:48] dedze: we are trying to run debsums to check which modifications have been made and then try to get its output posted to a pastebin [01:48] !pastebin | dedze [01:48] dedze: For posting multi-line texts into the channel, please use http://paste.ubuntu.com | To post !screenshots use http://imgur.com/ !pastebinit to paste directly from command line | Make sure you give us the URL for your paste - see also the channel topic. [01:49] tomreyn: http://paste.ubuntu.com/25202250/ Maybe I failed something [01:50] !pastebinit [01:50] pastebinit is the command-line equivalent of !pastebin - Command output, or other text can be redirected to pastebinit, which then reports an URL containing the output - To use pastebinit, install the « pastebinit » package from a package manager - Simple usage: command | pastebinit [01:50] tomreyn: Oki I think I kind of understand what we are doing [01:51] tomreyn: It did something new : http://paste.ubuntu.com/25202259/ [01:53] dedze: okay, if that's the entire output generated by " sudo debsums --all --changed" then i don't think you have an ebury infection there [01:54] Thank you tomreyn, I'm super new to Ubuntu and I did something stupid, someone I met on discord gave me a link to put into my browser starting by javascript: and I did it, do you think my computer could have been infected this way? === DogHackit_ is now known as DogHackit [01:57] dedze: possibly, yes. [01:58] So I already reinstalled Ubuntu since that [01:58] dedze: if you still have the exact code you were asked to put into the web browser, please paste it to pastebin, too [01:59] Actually it was taking the code from a website I think [01:59] dedze: which web browser did you paste it into? [01:59] There was a URL on it [01:59] firefox but I allowed the website in the link with noscript [02:00] dedze: unless you took measures to allow the javascript: handler, current versions of firefox would not execute it. [02:00] But actually, the script did something in the game === tharkun is now known as tharkun__ [02:01] It was about a browser game, and the purpose of the script was to write an identification code when we meet our teammate so we know for sure its not someone outside of our team === tharkun__ is now known as tharkun_ [02:01] So I think the code was executed [02:03] Monkeyhuouse: Sorry. I have been unable to come up with an exact means to obtain for you a meaningful result . [02:03] My last question and then I will stop bothering you, tomreyn, if I reinstall Ubuntu, do I get rid of any potential infection or not necessarily? [02:05] It still wont boot tomreyn. I tried mounting the root partition, chrooting in it, running update-initramfs but I still have the same issue when restarting. I'm not even sure I ran update-initramfs properly because the SO post doesn't seem to use LVm and I do. [02:07] dedze: maybe you opened firefox web console and pasted the code there, then it would have run. the firefox preference browser.urlbar.filter.javascript defaults to 'true' since ~ v6.0 and prevents javascript:... code, pasted to the url bar, from running, unless you have extensions installed which override this. [02:09] dedze: reinstalling would not necessarily have helped. executing the javascript code may have compromised your system user, not root. the reinstallation of ubuntu would not have replaced your home directory, so files placed there (such as those which are automatically executed when you login to your system user) would still be present. === r0Oter is now known as r00ter [02:09] dedze it actually depends on what code was executed, though, and how, if at all, the malware worked, and how you chose to reinstall. [02:10] tomreyn: I didnt save a single file, I chose the overwrite the whole disk while installing [02:11] I also don't have /dev/disk when I chroot [02:11] hfp_: i'm not sure which SO post you are referring to. did you fsck as i had recommended? [02:11] dedze: so all your personal files and configurations are gone? [02:12] dedze: no backups? [02:12] tomreyn: Yes, I did, it fixed a few errors. Then I mounted the partition and all my files are there. So I rebooted but no luck. Then I looked at this: https://askubuntu.com/questions/745218/ubuntu-wont-boot-because-of-lvmetad/752282#752282 (I thought you linked to it but maybe it was someone else). [02:12] tomreyn: Yes, everything was gone, it was exactly like when I installed Ubuntu the first time [02:12] tomreyn: And I had to rechoose names for my user, laptop name etc too [02:13] dedze: well then it's quite unlikely that anything persisted, unless this is a very very determined and experienced attacker [02:14] dedze: i'm just surprised you would happily delete all your personal files and documents. [02:14] tomreyn: Well then probably I'm safe no? I don't know why anyone would want to attack my laptop in the first place [02:15] dedze: unless you took a backup after the fact and restored that, i think you're most likely safe. [02:15] tomreyn: Hmm i'm the kind of person to not look behind me so much, so I don't get attached to things like photos etc [02:15] dedze: you should have told us you reinstalled deleting all data early on, this would have saved us some time. [02:16] I'm sorry tomreyn, that's true, I didn't think about saying it until when I did [02:16] dedze: but i'm sure you got plenty of adrenaline there, so that's ok ;) [02:16] tomreyn: Yes when I arrived here I was ready to cry lol [02:17] And I'm so paranoid, the first time I arrived here, a pasting was done by itself sometimes and I freaked out [02:18] It turns out its when I touch the top right of my touchpad, just a small tap, it pastes the last thing I selected hehehehe [02:18] hmmm my /boot on ubuntu-vg/root is empty... shouldn't it have a vmlinuz-KERNEL_VERSION and and initrd.img-KERNEL_VERSION? [02:18] hfp_: chroot again from a live cd running the same release as what you have installed. once everything is mounted (incl. virtual file systems like dev/pts, dev, sys etc.) and accessible paste 'lsblk --fs' and /proc/mdstat /etc/fstab /etc/crypttab and sudo dmsetup ls [02:19] tomreyn: how do I mount virtual file systems? I'm not sure I understand what that means :s [02:20] hfp_: https://askubuntu.com/questions/28099/how-to-restore-a-system-after-accidentally-removing-all-kernels#answers [02:20] first grey box [02:21] substitue /mnt by where you'll chroot to [02:21] Thanks for much for everything tomreyn . I wish you a good rest of day. Thanks!!!!! [02:21] dedze: and you, welcome ;) [02:23] tomreyn: so here is lsblk --fs: paste.ubuntu.com/25202444 [02:24] sorry, http://paste.ubuntu.com/25202444 [02:27] hfp_: no UUIDs? that's weird, is this from inside the chroot? did you mount --bind dev + proc + sys ? [02:28] also no fstypes, hmm, maybe not running as sudo? [02:29] sorry, i notice i didnt ask for sudo there explicitly, but assumed you'd be running as root anyways since you'll chroot. [02:30] tomreyn: yeah something's off... I did `sudo mount --bind /dev /tmp/data/dev`, also with proc and sys. But when I chroot into /tmp/data and try to apt install linux-image-generic --reinstall, it complains that /dev/pts might not be mounted [02:34] hfp_: please exit the chroot and mount --bind /dev/pts as well, then re-enter the chroot [02:34] this bit is missing from the instructions i linked to [02:35] so: sudo mount --bind /dev/pts /tmp/data/dev/pts; sudo chroot /tmp/data /bin/bash [02:36] tomreyn: ok, the output of lsblk --fs is still the same though [02:36] hfp_: if you run it outside the chroot, too? [02:36] now apt install linux-image-generic --reinstall runs ok but /boot still doesn't have a vmlinuz [02:37] tomreyn: outside the chroot it has UUIDs [02:37] http://termbin.com/ll0h [02:37] outside of chroot, can you show "sudo mount" as well, please [02:38] Why is my AMD Radeon HD 6670 not being blacklisted :( https://paste.ubuntu.com/25202501/ [02:39] http://termbin.com/so8p [02:40] tomreyn: I had an other idea [02:40] tomreyn: I used my webcam on skype in a call and I ran the command sudo lsof /dev/video * [02:41] Of course because I'm paranoid as always [02:42] And it gave this result: http://paste.ubuntu.com/25202545/ [02:42] Is it abnormal? [02:43] dedze: i don't know your system so i don't know what's abnormal for your system. if you have skype installed, and 'ps ef 1955' looks like it is the legitimate skype process then there's nothing unusual about this output [02:45] hfp_: looks like you have plenty of /dev/pts bind mounts now ;) but you don't have /boot mounted ( i assume it resides on a separate partition) [02:46] tomreyn: oh yeah it could be that /boot is on another partition... how do I find out where is it? [02:46] Oki thank you tomreyn [02:47] hfp_: based on the lsblk output you provided it is probably sda2 [02:47] hfp_: you could check /mnt/data/etc/fstab to know for usre [02:48] sda2 is 0c2f1b2d-4dca-4a7c-aca4-dd9d8c0f2606 [02:48] grep boot /mnt/data/etc/fstab [02:48] indeed sda2. so do I mount it at /tmp/data/boot so it's hopefully in /boot when I chroot, or do I mount it somewhere else? [02:49] hfp_: make sure you clear out /tmp/data/boot now that you probably wrote stuff there before you mount sda2 to it. [02:49] but keep the directory [02:50] do I need to mount --bind or just a plain mount? [02:51] I never understood what --bind does [02:54] hfp_: --bind basiclly just makes a file system that is already mkounted also appear at this additionat target [02:54] /boot is not mounted, yet, so mount it normally, without --bind [02:55] to be precise, the /boot file system of your 'normal' ubuntu installation is not currently mounted, yet. [02:55] ah I thnk I know what happened! it's not the wbfs thing, I had issues with grub-efi a few weeks ago and i ran apt update yesterday, it updated grub-efi and friends. now I rebooted and that's probably why it wont reboot anymore, something has changed there [02:56] because I see all the vmlinux and initrd.img in the chrooted /boot [02:56] so no need to reinstall them I guess [02:57] hfp_: i suspect that sda1 is to be mounted to /boot/efi as well [02:57] yes [02:58] I think the problem has to do with grub and efi, but I don't know what the problem is for sure nor how to confirm my suspicions [03:03] onc3e you have the efiboot and just one /dev/pts mounted, chroot again and show /etc/fstab, /etc/crypttab, dmsetup ls [03:04] tomreyn: how do I unmount them? umount /tmp/data/dev/pts says target is busy. is it the right way of doing it? [03:09] hfp_: umount /dev/pts until you have none left (be sure to have exited the chroot beforehand), then just "mount /dev/pts" and "mount --bind /dev/pts /tmp/data/dev/pts" [03:09] use the "mount" command to verify you end up with what you should have [03:10] that;s the thing, I cant umount /dev/pts it says device is busy [03:14] hfp_: okay you can just keep /dev/pts of the live system, but remove all but one of those you mounted to /tmp/data/dev/pts [03:15] should I force umount? I get the device is busy either for /dev/pts or /tmp/data/dev/pts [03:17] hfp_: dont force unmount, can i see "mount" again on pastebin? [03:18] which directory are you in now? outside of chroot? [03:18] yes I'm in ~ on the liveusb, out of chroot [03:18] trying to `sudo umount /tmp/data/dev/pts` [03:18] I still have multiple /tmp/data/dev/pts mounts [03:19] did you umount -f anything, yet? [03:19] http://termbin.com/lqrw [03:19] didnt force anything yet [03:20] and "mount" says what? the exact same as at http://termbin.com/so8p ? [03:20] yes, this is the one I just ran: http://termbin.com/lqrw [03:25] try this (outside chroot): sudo umount /dev/pts; sudo umount /tmp/data/dev/pts; sudo umount /dev/pts; sudo umount /tmp/data/dev/pts; sudo umount /dev/pts; sudo umount /tmp/data/dev/pts; sudo umount /dev/pts; sudo umount /dev; sudo umount /tmp/data/dev; mount | pastebinit [03:25] hfp_: ^ [03:26] you have plenty of duplicate mounts currently [03:27] it wont send anything through the pipe, the error goes to stderr [03:28] in any case, this is the error http://termbin.com/141z [03:28] tomreyn: ^ [03:29] oh right [03:30] this can't be the 'mount' output though [03:30] what is it the output of? [03:30] no that's the output of sudo umount /dev/pts and sudo umount /tmp/data/dev/pts [03:30] outside of the chroot [03:31] hmm dunno then, maybe reboot [03:32] yeah that will be easier [03:34] alright, I rebooted and I have the ubuntu-vg/root mounted at /tmp/data [03:35] better mount to /mnt/target or something, not to /tmp [03:35] but i'm happy to try with either, /tmp's just not a great place to mount to [03:37] so, fstab: http://termbin.com/gl99 and crypttab http://termbin.com/t534 [03:39] dmsetup ls ? [03:40] http://termbin.com/m8zk === gomjabbar is now known as GomJabbar [03:44] and finally lsblk --fs && mount [03:44] and finally sudo lsblk --fs && mount [03:44] hfp_: ^ [03:44] tomreyn: http://termbin.com/resr [03:45] that's within the chroot [03:45] out of it: http://termbin.com/pi90 [03:47] can you, inside the chroot: sudo cp -p /proc/mounts /etc/mtab [03:48] i suspect that will make 'sudo lsblk --fs' work inside the chroot [03:50] ah, you missed to bind mount /dev [03:52] hfp_: so it's: exit chroot, then: cd; sudo umount /tmp/data/dev/pts; sudo mount --bind /dev /tmp/data/dev; sudo mount --bind /dev/pts /tmp/data/dev/pts; chroot /tmp/data /bin/bash [03:54] then make sure /etc/mtab looks the same as /proc/mounts, if it isn't: sudo cp /proc/mounts /etc/mtab [03:58] they're the same [03:59] then, if you also ran the other commands above, lsblk --fs should now list uuids inside the chroot [03:59] lsblk --fs within the chroot still doesnt have uuids [03:59] Hi everybody. Does anybody here run Visual Studio in Ubuntu? I'm wondering what the best way to go about it is. I need it for my studies. [04:00] tomreyn: i'm sorry it's getting very late and i'm falling asleep. can you tell me what you had in mind so i can try and continue tomorrow? or if you're on the channel we can pick up where we left off? [04:00] hfp_: did you bind mount /dev into the chroot though? [04:02] hello i need to reinstall my windows . do i have to make a boot repair cd and run it after that? dual boot [04:02] hfp_: so the idea is to make the chroot into an environment where everything needed is present to determine where to install grub to, and how to layout the initrd so that a boot can succeed. all of these virtual file system bind mounts are needed for this purpose, and uuids need to be known to the chrooted system. you can also test this using 'blkid' [04:03] effectnet: I would suggest downloading the Windows 10 Creation Tool and making a bootable USB. When dual booting, it's always best to install Windows first. [04:03] the windows needs a reinstall is all === mundus2018 is now known as HalfEatenOut [04:06] hfp_: once that's succeeded you could review /etc/crypttab and /etc/fstab and make sure all the corre4ct UUIDs are in place in these files, and that pvs + vgs + lvs look correct, too. then you could update-initramsfs -k all and update-grub and grub-install /dev/sda (though reinstalling grub is optional) === HalfEatenOut is now known as HalfBakedPie [04:07] hfp_:i'll probably be around tomorrow but not yett sure at what time. === r0Oter is now known as r00ter [04:08] i recommend taking notes on all the commands you need to run before chroot (and after, too) === HalfBakedPie is now known as mundus2018 [04:58] well that boot repair disk didn't work [04:59] how do i reinstall grub now? [05:00] !grub | effectnet [05:00] effectnet: GRUB2 is the default Ubuntu boot manager. Lost GRUB after installing Windows?
