[00:29] lmao [00:32] Anyone here has experience with linux kernel drivers [00:33] Come on dont be Chad and Stacy on #ubuntu [00:36] apt update; apt upgrade ; apt autoremove; on supermicro made my keyboard and network stop working. [00:37] i had to boot off an older ubuntu 16.04.1 iso into a rescu environment and install a different kernel 4.12.0 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12/ [00:37] can anyone help me [00:37] very strange. [00:37] GriffusSilver: what do you have? [00:39] why do i keep getting deauth'd on my wifi network [00:39] just look at my dmesg for example [00:39] wlan0: deauthenticated from ac:0d:1b:d8:f5:e3 (Reason: 3=DEAUTH_LEAVING) [00:39] [ 9004.394210] wlan0: authenticate with ac:0d:1b:d8:f5:e3 [00:39] [ 9004.394669] wlan0: send auth to ac:0d:1b:d8:f5:e3 (try 1/3) [00:39] [ 9004.398171] wlan0: authenticated [00:39] [ 9004.407628] wlan0: associate with ac:0d:1b:d8:f5:e3 (try 1/3) [00:39] [ 9004.421910] wlan0: RX AssocResp from ac:0d:1b:d8:f5:e3 (capab=0x431 status=0 aid=4) [01:04] ugh maybe i should have gone with 17.04 instead of 16.04, having issues that may or may not be ryzen related, but with mainline kernel have no clue how to get zfs module working [01:09] Seems I need to fsck /home - but it is mounted. How do I login as root so I can umount /home [01:11] Hi [01:11] please help me regarding... [01:12] whenever I boot this is coming [5^ [5^ [5^ [5^ [5^ [5^ [5^ [5^ [5^ [5^ [5^ [01:14] rahulprodev: starting with the simple trouble shooting Qs first - do you have a disk/USB plugged, one you forgot to take out the last time the system worked? [01:15] [01:15] [01:16] w9qbj, thanks for reply.. actually i reinstalled ubuntu many times still this comes up everytime [01:17] Seems I need to fsck /home - but it is mounted. How do I login as root so I can umount /home - or how to I force a fsck at boot Ubuntu 16-04 [01:23] w9qbj: You will need to unlock the root user to be able to do that. [01:23] Or you can force a fsck /home on a reboot and then reboot. === bomb_ is now known as bomb [01:42] !zfs | MBS [01:42] MBS: For information concerning ZFS and Ubuntu, see: https://wiki.ubuntu.com/ZFS [01:46] well im currently compiling 4.12 w/ ZFS and will see if it works and stops hangs [01:49] rahulprodev: wich ubuntu iso? [01:51] lotuspsychje, 16.04 [01:52] rahulprodev: how did you create usb? [01:55] lotuspsychje, usb create by universal usb installer [01:56] i tried many times but this error is coming again and again. [01:57] rahulprodev: explain what happens exactly plz: uefi settings? usb plug in, load ubuntu? when do you get errors? [02:01] I don't have that much idea about ubuntu... that much about about after booting first screen flashes then this error comes. [02:02] is it possible it will be hardware problem... because now my windows is also not installing [02:02] rahulprodev: Are you getting this message when you're booting Ubuntu's installer, or when booting Ubuntu after having installed it? [02:02] after installed [02:04] rahulprodev: Do you ever see the grub menu at boot? [02:04] grub menu you mean red screen where ubuntu options comes? [02:05] yes... after that screen flashes and this error show up [02:06] rahulprodev: The purple screen with "Ubuntu" and "Advanced options for Ubuntu", yes. Have you tried selecting "Advanced options for Ubuntu" then the "Recovery" option? [02:09] Jordan_U, I didn't tried, actually i reinstalled many times... [02:10] recommended place for snap assistance? [02:11] #snappy [02:11] awesome, ty [02:12] welcome [02:13] On ubuntu server, nmcli says i'm "connected" to a wifi network, but i can't ping the router "destination host unreachable" [02:18] rypervenche: for some this might be a dumb Q, but how do I force a FSCK on reboot? [02:19] energizer: does 'ip a' show your interface to have an ip address? [02:20] w9qbj: What OS and version? [02:20] ubuntu 16.04 [02:20] willdeberry: yes [02:22] rypervenche: I have Uuntu 16.04 [02:26] energizer: if you have net-tools installed, you should have the route command. does it show your router as the default route? [02:35] rypervenche: i believe putting fsck.mode=force as a kernel command line option should do the trick: https://www.freedesktop.org/software/systemd/man/systemd-fsck@.service.html [02:35] hey guys! just built a new PC and i'm now up and running. i am booting from a smaller SSD and also have another internal HDD. does it make sense to mount that with/inside of my home directory, or leave it in /media or /mnt? what is the natural convention for additional non-removable disks [02:39] !home | BUSY [02:39] BUSY: Your home directory is where all of your personal files are usually kept. For moving your home directory to a separate partition, please see: https://help.ubuntu.com/community/Partitioning/Home/Moving [02:40] is that what i ought to do? i was wondering if the disks could sort of have nesting mount points [02:41] BUSY: how big is your ssd? [02:41] 500GB [02:42] BUSY: and your internal HD? [02:42] willdeberry: Yeah, thanks. I got a phone call. [02:42] rgr [02:43] 4TB, i suppose smaller is a relative term, and i am doing more than booting. currently my home directory can fit fine on the SSD, but i just was not sure how i ought to introduce the other drive when i am interested in using it, if not from its default /media/ mount point [02:45] BUSY: booting your ssd with ubuntu would be a good idea [02:45] BUSY: what i would do is: install ubuntu install and /home on the ssd and keep the 4TB as data/backup drive internal [02:46] that is the configuration i have now, i am just not sure where to mount the 4TB that would make logical ubuntu sense in the directory hierarchy [02:47] does it make any sense to have it inside of ~? [02:47] willdeberry: route gives an empty table [02:48] oh no i guess it was just loading it says gateway 192.168.0.1 [02:49] or maybe i just mount it in /media and link it in home? i suppose i can do whatever i want, but i was just seeing what people naturally did with more than one drive [02:50] energizer: and that's the same address you can't ping right? [02:50] willdeberry: right [02:51] <[n0mad]> BUSY: i just leave mine mounted in media [02:51] willdeberry: pinging it says "From .111", which is the eth0 ip, not the wlan ip. eth0 isnt plugged in [02:52] [n0mad], /media/disk_name? by default, it looks like it goes to /media/username/uuid/ [02:52] <[n0mad]> yes, /media/user/disk [02:53] <[n0mad]> i think really it's up to you, but i figured where ubuntu put them is good enough for me [02:53] sounds reasonable enough [02:54] ok cool, got 4.12.7 with ZFS running now, hopefully no more crashes :( [02:54] i'm trying to statically build an x11 application but i'm getting link errors [02:55] https://bpaste.net/show/bdc96e51274a [02:56] cores: I think you forgot -lXt [02:56] at first i didn't think my X libraries that i installed were built for static linking, but the symbols the linker is looking for are in the file /usr/lib/x86_64-linux-gnu/libXt.a [02:56] Stanley00, huh i didn't try that [02:57] Stanley00: doesn't apper to work [02:58] willdeberry: anyway, what do i do now? [02:58] i got a bunch of link errors [02:59] cores: you still get the *same* error messages after adding -lXt? [03:00] $ gcc -static -o push push.c -L/usr/lib/x86_64-linux-gnu -lXt 2>&1 | grep "undefined reference" | wc -l [03:00] 500 [03:01] different list of undefined references [03:01] cores: then you will need many more -l switch, -lXt is just simply not enough [03:02] hmm, no undefined refs that start with -Xt any more though [03:03] cores: yes, -lXt just provide some *refs*, you will have to find which library provide other *refs* you need and add -l option for that lib [03:05] willdeberry: looking in tshark i see "38 120.70... ba:27:eb:2d:9e:53 -> Raspberr_2d:9e:53 .... Ethernet" [03:07] does the ip command show eth as down or just no ip? [03:17] Stanley00: i'm down to 2 undefined references [03:17] form a max of about 2300 [03:17] cores: wow, congrat :3 [03:19] energizer: and i only assume this worked at some point? [03:20] back up to 161 :( [03:23] anyways energizer, i am just shooting in the dark here honestly...this is one of those issues that is hard to narrow down unless it is just a driver issue [03:25] is there a way for the linker to automatically find and resolve all these references? [03:27] i finally ran into a library that doesn't have the symbols i need [03:27] give up time [03:31] willdeberry: ok here we go. `ifconfig eth0 down` then it suddenly works [03:34] willdeberry: /etc/cnetwork/interfaces.d/50-cloud-init.cfg has auto eth0; iface eth0 inet dhcp; [03:37] im compiling curl by hand. long story. its linking against older openssl, probably because its finding that lib before the 1 i compiled and installed via checkinstall [03:38] so, is that something i can likely inform via configure flags or do i dig in the makefile? [03:39] or, is there something i need to do to inform ld of this [03:41] apparently the order of -l options passed to gcc matters a lot [03:43] well i just ran ldconfig, idk if it was run during checkinstall. ima try that and then look in the makefile then [03:49] i never gave up :( [03:49] hi [03:49] its midnight and i'm down to 4 undefined references [03:49] all of which are defined in libX11.a [03:49] but the linker still isn't liking something [03:49] in ubuntu 17 how do I uninstall python2.7 and install python3.6? [03:50] nick---: why would you uninstall any python [03:50] because i need python 3.6 [03:51] i think apt-get install python3 [03:51] but also maybe look into a version manager [03:51] idont know of any [03:51] but i cannot recommend the solution to be uninstalling python2.7 [03:55] oh wait its linking against not the right libcurl. weird, curl itself builds libcurl [03:56] or no. this is all sorts of wrong [03:59] Stanley00: finally got it to work [04:00] Stanley00: i had to put the -lXft BEFORE the -lX11 [04:00] i can finally go to sleep [04:01] cores: yeah, I don't know why but sometime you have to messing around with the order of linked libs. g9 [04:02] my statically built app wont run on another machine lol [04:03] XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":1.0" [04:03] after 101 requests (101 known processed) with 0 events remaining. [04:03] Segmentation fault [04:04] it runs on the machine i built it on, ubuntu 16.04 [04:04] oops i mean 17.04 [04:04] but wont run on ubuntu 14.04 [04:07] well what resource could that be [04:08] i have no idea [04:09] it runs on ubuntu 16.04 [04:09] runs on 16.04, 17.04 but not 14.04 [04:09] ah well, looks like that's as good as i'm going to get for now [04:11] i wonder if it will work if i do it the other way around: build on 14.04 and try running on 16.04 or 17.04 [05:01] hubby's ubuntu 16.04 box is crashing at odd times. I thought it was his weather app, dialing in and failing, so he removed that. But i was just now going to look something up on ff and it just .. crashed! it restarts ok, but he has been experiencing this a lot lately. Help? [05:14] chalcedony it could be a lot of things. I would check to make sure the system isn't running out of ram and hard drive space first [05:14] ok [05:15] ddellav, are there commands for that? [05:15] chalcedony yes, free -m for memory and df -h for hard drive space [05:15] ty very much ddellav :) [05:15] yw [05:15] let's see [05:17] hello [05:17] anybody alive [05:18] https://pastebin.com/TJ1gz3mf ddellav [05:19] reans ask your question if you need help [05:20] chalcedony ok, looks like everything is fine there [05:20] ddellav, it dosen't look like ram is the culprit [05:20] next, check dmesg for errors [05:20] just type dmesg and hit enter [05:20] help help! [05:21] his directory is full, he can't run updates (he is fixing that i think) [05:21] infotek, ask a question please [05:21] ok ddellav [05:21] as far as ssh public key safety, i could theoretically broadcast it to anyone, right? [05:21] fyi i didn't see any full directories in that output [05:21] chalcedony [05:22] BUSY what do you mean safety? [05:22] ddellav, he's got an error on the update [05:22] a pub key does not grant access to any resources is thats what you mean [05:22] i guess privacy. if the private key is kept private, the public could fall into anyones hands? [05:23] with no consequences [05:23] yes, thats why it's called the public key [05:23] its meant to be given out [05:23] i see. that makes sense, if authorized_keys is like a whitelist, i just wasn't sure if you should only send your public to known hosts [05:24] it's fine to send it anywhere :) [05:24] ddellav, is there a pastebin command for dmesg? [05:24] i refuse to use my words. [05:24] I'm not sure what you mean chalcedony [05:25] just look and see if you see any segfaults or anything that looks bad [05:25] additionally you can look in /var/log/syslog [05:25] it will have similar info [05:25] chalcedony: my words! I refuse to use them! [05:25] ddellav, syslog said something about chron [05:26] there will be entries about cron in the syslog, unless there's an error somewhere though it should be ok [05:26] 1.615154] i8042: PNP: PS/2 appears to have AUX port disabled, if this is incorrect please boot with i8042.nopnp [05:27] what's going on with your cron? [05:28] chalcedony: that was your kernel telling you about a useful kernel parameter. [05:28] 56.694061] cgroup: new mount options do not match the existing superblock, will be ignored [05:28] 1.707332] MXM: GUID detected in BIOS [05:30] i don't know enough to know, but nothing is jumping out [05:30] chalcedony: what is going on? [05:30] chalcedony: your errors seem random and would warrant a memtest. [05:30] infotek, oh? [05:31] [01:01:41] hubby's ubuntu 16.04 box is crashing at odd times. I thought it was his weather app, dialing in and failing, so he removed that. But i was just now going to look something up on ff and it just .. crashed! it restarts ok, but he has been experiencing this a lot lately. Help? [05:32] chalcedony: define crash. [05:32] chalcedony: did the machine reboot? [05:32] no it dies [05:32] chalcedony: define dies [05:32] the power light stays on but nothing else [05:32] screen goes black [05:32] fans stop turning [05:33] chalcedony: i would certainly look at ram while suspecting also video card/memory. [05:33] requires manually switching off the power supply and restarting [05:33] fans stop turning is interesting. [05:33] even cpu fan? [05:34] im not sure [05:34] he keeps the computer a long way from where i stand [05:34] the power supply did not seem to be turning when i restarted it for him th is last time [05:35] it is not a cheap or old power supply [05:35] i would check ram. cpu registers, cache video memory. [05:35] ok tell me how :) i'm ssh'd to him [05:36] you situation sounds like a hardware malfunction. [05:36] i would concur [05:36] its summer and this is georgia.. what would summer be without a heardware problem? [05:37] chalcedony: i am in alabama [05:37] * chalcedony throws a stone [05:37] yea, if your system is physically turning off then it's a hardware issue [05:37] I use amidiag but it is commercial. [05:37] i thought you meant the application crashed lol [05:37] ddellav, ah no the thing has to be restarted [05:38] i have vps but when i install 16.04 os it was successfully installed but it seems no server daemon run in bootup. i cant access ssh and even to ping the ip not reachable any idea to fixed the issue is highly appreciated [05:38] chalcedony: when you boot from a recent ubuntu you get a menu item taht says memtest [05:38] i see [05:38] reans sounds like it wasn't installed properly [05:39] chalcedony: but if the cpu, cache, mb are bad you will get failed memtest. [05:39] though if you did the install yourself, i hope you chose to install the SSH server, otherwise yea, there will be no way to access it remotely [05:39] then again you are unlikey to boot into a gui with cpu/cache issues. [05:39] it boots ok [05:40] if it has a lot of memmory and two or more sticks, you can remove half and see if it still works. [05:40] but when i login the vps via console and run the services from console it will work but there is a certain when i configure like docker it seem error in bus not found something [05:41] if it fails swap the sticks. [05:41] try again. [05:42] divide and conquer. [05:42] infotek, we can do that, he says [05:42] give us a couple [05:47] chalcedony: infotek: If you boot the Ubuntu live media from a UEFI based machine you will not see a memtest option, because memtest86+ only supports BIOS. [05:48] if that is an issue you can download and write a recent version which supports both BIOS and UEFI chalcedony [05:48] MemTest86 V7 images supports dual booting (UEFI/BIOS) [05:49] chalcedony: infotek: You can use memtester from within a booted Ubuntu system, but it will only be able to test as much memory as it allocates, and it won't be able to allocate memory that's already in use by any other process. [05:50] Jordan_U: can you noop sled into a remote system and test memory abitrarily? [05:50] infotek: It's not so much that that's a more recent version, it's that the proprietary fork of Memtest supports UEFI and the open source version (memtest86+) doesn't. [05:54] infotek: Even if you can find an exploit that allows you to write to and read from all of memory, your system won't stay up very long if you're constantly overwriting other process' memory. [05:55] Does Ubuntu-Make work reasonably well from within an LXC container? [05:55] infotek: If you're not booted via secure boot then you can just write to and read from /dev/mem. That's just not a terribly good idea :) [05:57] Jordan_U: it is a terribly good idea :) [06:01] ok guys, bed for me. [07:01] Can anyone help me out .... I'd like to multitail aprox 20 log files and only print the lines that contain a comma "," Can I use multitail and maybe sed -n '/,/p' ?? thanks! [07:02] dcypher: cat *.log | grep , [07:03] and then it stops [07:03] I'd like to tail the logs [07:03] I'm thinging multitail [07:03] thinking [07:10] How do I disable a systemd service (so it doesn't load on boot)? Google tells me 'sudo systemctl disable alsa-restore' should do it, but after boot, that service is still "active (exited)". (Ubuntu 16.04, if is relevant) [07:15] probably SomeOtherService loads it, and 'systemctl mask alsa-restore' is a more forceful command :) [07:18] kraiskil: you have to mask it [07:19] nevermind :D [07:19] Thanks anyways :) [07:50] <_Timon> Hi, I want to setup a local package mirror for our internal enviroment. I see apt-mirror being recommended in some places, but due to the recommended size of 120GB I am confident that this only includes the distro itself, and not the package repository. [07:51] <_Timon> I've also seen ubuntu site itself recommend rsync and ~600GB of storage, but I think that that also includes older ubuntu installations that I don't require. [07:53] <_Timon> Basically I want all supported packages for Xenial and Xenial itself on a local server. [07:54] 120GB sounds like a good size for it [07:55] <_Timon> So apt-mirror and "deb http://archive.ubuntu.com/ubuntu xenial main restricted universe multiverse" should do the trick? [08:14] dcypher: tail -f *.log | unbuffer grep , [08:17] also: `grep --line-buffered` [08:17] no need for unbuffer [08:17] only necessary if you pipe grep to something [08:31] Hello! [08:32] I have a strange problem with my Ubuntu 14.04 hardware server - it sometimes suddenly reboots (last shows "reboot system boot") but I cant figure out what or who exactly initiated the reboot command [08:33] frdmn: does auth.log tell? [08:33] I went through "last", "dmesg", "syslog" "kern.log" [08:34] tomreyn: no authoriztion/login events at all [08:34] Intressting enough, the reboots usually happen on ~06:59 [08:34] http://paste.frd.mn/raw/ogasu [08:34] but the day it happens seems to be varying [08:35] I also went through all crontab / cron.d's as well as at-jobs [08:35] unattended-upgrades? [08:35] :o [08:37] I have to check where to find it's schedule [08:37] does it has a separate log, because I see some entries in the apt history log [08:38] tomreyn: http://paste.frd.mn/raw/orugi [08:38] grep Automatic-Reboot-Time /etc/apt/apt.conf.d/50unattended-upgrades [08:39] is it commented in or out? [08:39] commented in: http://paste.frd.mn/raw/refov [08:39] so it's something else [08:39] crud, I thought it's promising [08:40] tomreyn: what I find interesting is that the dmseg logs match the time whenever the reboots happen: [08:40] tomreyn: http://paste.frd.mn/raw/wizez [08:40] but, i couldn't find anything suspicious in there [08:42] frdmn: chances are that your daily cron jobs run at this time as per "grep daily /etc/crontab" === the_ant1 is now known as the_ant [08:43] tomreyn: seems to run at 06:25 - http://paste.frd.mn/raw/tazus [08:44] so half an hour earlier [08:44] yeah exactly [08:49] frdmn: this lists past shutdowns and runlevel changes, it might help to correlate those to the reboot times: last -x | less [08:52] tomreyn: aha! [08:52] it looks like when ever it happens, it switches the active kernel? [08:52] http://paste.frd.mn/raw/uvixo [08:54] which is why i was assuming unattended-upgrades. maybe run "apt-config dump | grep -i reboot" just to be sure it's really off [08:54] LOL [08:54] tomreyn http://paste.frd.mn/raw/otede [08:54] okay, case closed [08:55] so it's configured elsewhere [08:55] any idea where it could be configured? [08:55] should I maybe do the dpkg-recofnigure on the package? [08:55] well surely somewher ein /etc/apt/apt.conf{,.d/} [08:56] hi guys, does ubuntu kernel 4.6-* supports amd GPU driver already? [08:56] i just upgraded the kernel, been struggling with my amd, since i was reading that the latest ubuntu kernel dont support amd till undefined period of time [08:57] tomreyn: /etc/apt/apt.conf.d/local it is :) [08:57] i guess the last time that ubuntu supported amd was in ubuntu 14.0x something [08:58] please share the info if you have any, thanks. [09:00] frdmn: congrats.;) some deployment mechanism may have put it there, such as puppet, chef or ansible [09:01] tomreyn: or the other alternative - the coworker who didn't add those parts to the server documentation :D [09:01] tomreyn: thanks a lot for your assistance [09:01] but would he ever do that!! ;) [09:01] welcome [09:02] welcomeparty: you use kernel 4.6 with which ubuntu release? [09:02] tomreyn: maybe you also can help with my originating problem, it appears that this sever lost the java binaries on the last reboot [09:02] ANY idea how this could happen? [09:02] I just saw that the bins in /usr/lib/jvm/java-7-openjdk-amd64/bin/* were deleted [09:02] the symlinks in /usr/bin/ were still there [09:03] frdmn: if those were packaged (.deb) and removed via apt then /var/log/apt/term.log should say. [09:03] I fixed it by purging through dpkg and reinstalling through apt (where they came from) [09:03] or /var/log/apt/term.log* rather [09:04] tomreyn: from term.log: http://paste.frd.mn/raw/amayo [09:04] interesting... [09:04] frdmn: the older files then [09:04] hi, to fix the intel bug on skylake i have to simply install this package? intel-microcode [09:04] the older files don't match the time [09:05] seven-eleven: it's worth a try. [09:05] there are some previous events in term.log as well just pasted the relevant times [09:05] but those are at least one week before the incident [09:06] frdmn: then use auth.log / last to tell who was logged in and may have removed those manually [09:06] tomreyn, i can't and don't want to trigger the bug on my production server, that's why I need verification by the community :-] [09:06] tomreyn: that's the weird part - noone was on there [09:06] it has to be happend automatically somehow [09:07] https://bugs.launchpad.net/ubuntu/zesty/+source/intel-microcode/+bug/1700373 [09:07] Launchpad bug 1700373 in intel-microcode (Ubuntu Zesty) "intel-microcode is out of date, version 20170707 fixes errata on 6th and 7th generation platforms" [Undecided,Fix committed] [09:07] along with the sudden (and now solved) reboot [09:07] seven-eleven: i haven't heard of using intel microcodes making things worse rather than better. i do not know which "intel bug on skylake" you are especifically referring to, though. [09:08] people where is the .bashrc file? [09:08] tomreyn, https://arstechnica.com/information-technology/2017/06/skylake-kaby-lake-chips-have-a-crash-bug-with-hyperthreading-enabled/ [09:08] acresearch: in your home folder [09:08] thanks [09:09] ahh hyper threading is enabled on my machine "dmidecode -t processor | grep HTT" [09:09] so i need to install it i reckon [09:10] seven-eleven: to make use of microcodes you'll need to reboot anyways, so if that impacts your production server too much you may need to setup HA beforehand. [09:10] tomreyn, i got only like 5 visits a day on my webserver so shouldn't matter :-] [09:11] seven-eleven: maybe you need OOB ;) [09:12] yeah :-) [09:13] welcomeparty: still around? [09:14] tomreyn: yes [09:14] welcomeparty: did you spot the question i asked? [09:15] tomreyn: come again please? [09:15] welcomeparty: you use kernel 4.6 with which ubuntu release? [09:15] tomreyn: ubuntu 16.04 xenial [09:15] welcomeparty: i don't think 4.6 is an official ubuntu kernel package, not at this time. [09:16] tomreyn: i grab it on some site [09:16] what is the latest official release tho? [09:17] tomreyn: based on this: there were kernel updates on each incidents right (aug-15 and aug-16): http://paste.frd.mn/raw/qemiv [09:17] How come I don't see those in the apt history? [09:18] this is from the history.log: http://paste.frd.mn/raw/apalo [09:18] welcomeparty: xenial (16.04.0) comes with 4.4.0, but offers newer kernels through HWE https://wiki.ubuntu.com/Kernel/LTSEnablementStack [09:18] !hwe | welcomeparty [09:18] welcomeparty: The Ubuntu LTS enablement stacks provide newer kernel and X support for existing LTS releases, see https://wiki.ubuntu.com/Kernel/LTSEnablementStack [09:21] frdmn: what you posted shows a kernel upgrade taking place on 2017-08-16 ("aug-16") [09:21] I have an odd request [09:21] I've managed to delete my running 4.4 kernel from a Ubuntu 14.04 server [09:21] it's still booting because it can boot 3.13.0-128-generic [09:22] I want to restore the 4.4 kernel, so I tried this: sudo apt-get remove --purge linux-image-generic-lts-xenial linux-headers-generic-lts-xenial linux-generic-lts-xenial [09:22] then reinstalling those packages [09:22] however that doesn't seem to help and it's still missing from /boot [09:22] tomreyn: is there anyway to upgrade thro apt-get method? or need to download the kernel by single dpkg? [09:22] frdmn: it doesn't show it on 2017-08-15, but maybe the log is incomplete or the other kernel upgrade happened earlier. [09:22] tomreyn: but shouldn't I also see those in apt history log? [09:23] frdmn: you do. as i said, the apt hiostory log you posted to the pastebin shows a kernel upgrade [09:23] ah, gotcha [09:23] gnomethrower: wait, i dont think that kernel image is removable by apt-get method? [09:24] welcomeparty: Correct... it's a long story :( [09:24] gnomethrower: why dont you reinstall the prev kernel by downloading it again, and installing it via dpkg -i kernel-*.deb? [09:25] welcomeparty: I want to install the most current 4.4 kernel as recommended for Xenial [09:25] not sure where to find a deb of that [09:25] gnomethrower: there are sites to find it, i guess [09:25] welcomeparty: upgrade to what exactly? [09:26] tomreyn: can upgrade or install the latest kernel using apt method? [09:26] i never done it tho [09:26] but just asking [09:27] welcomeparty: Hell yes :) https://askubuntu.com/questions/298853/how-to-reinstall-newest-linux-kernel [09:27] That was actually fairly easy [09:28] gnomethrower: please run these commands and show the entire in- and output on a pastebin: lsb_release -ds; sudo apt-get update; sudp apt-get -f install; sudo apt-get install linux-image-generic-lts-xenial linux-headers-generic-lts-xenial [09:28] thats unless you just solved the issue. [09:28] welcomeparty: you can install the latest HWE kernel using apt, yes. [09:29] you could also install mainline kernel through apt, if you were using a PPA providing them, but that's unsupported. [09:29] tomreyn: No, that fixed it :) Thanks everyone for the help [09:29] tomreyn: since i just read the HWE kernel is all about supporting the latest hardware, then what's the main diff with generic kernel? [09:29] welcomeparty: ...and you probbaly dont need / want to resort to mainline kernels [09:30] tomreyn: mainline kernel refers to? [09:30] welcomeparty: the main difference is that the HWE kernel supports newer hardware. [09:30] welcomeparty: mainline refers to what kernel.org provides. [09:30] tomreyn: alright. what are you using? [09:31] welcomeparty: that doesn't matter. what are you trying to achieve? [09:31] tomreyn: which is better? well, i wanted to utilize my GPU by enabling its driver, but i dont know the impact if i install the HWE [09:33]
