[09:37] <PaulePanter> Hi. Any idea, why the latest Linux HWE kernel is not installed in my Ubuntu 16.04.7 VM?
[09:37] <PaulePanter> https://paste.debian.net/1162732/
[09:39] <lotuspsychje> !info linux-image-generic-HWE-16.04 xenial
[09:39] <PaulePanter> lotuspsychje: Thanks. I remember why I removed it.
[09:40] <PaulePanter> It depends on the microcode update packages, and *thermald* gets installed too. :(
[09:40] <PaulePanter> *I remember why it was removed. (As I wanted to shrink the image and removed some of its dependencies.)
[09:40] <PaulePanter> Do you have a solution for that?
[09:43] <PaulePanter> It looks like, I have to manually keep it updated:
[09:43] <PaulePanter> sudo apt install linux-image-4.15.0-115-generic linux-modules-4.15.0-115-generic
[09:43] <PaulePanter> … if I do not want the dependencies in a VM.
[09:43] <PaulePanter> *QEMU (KVM) VM
[09:56] <tomreyn> PaulePanter: linux-virtual-hwe-16.04
[09:57] <tomreyn> or linux-virtual rather
[09:58] <tomreyn> there appears to be no hwe support for virtual in xenial
[09:59] <tomreyn> but you should probably plan to upgrade soon, anyways.
[12:32] <SamuelMarks> hi
[12:33] <SamuelMarks> What are my options for 12.04? - Can I downgrade from 16.04? - I'm working from the 12.04 iso and am trying to turn it into a custom cloud image.
[12:33]  * SamuelMarks needs 12.04 for an old version of Open edX; then he'll restore his backups and upgrade to the next version, and so on, until I'm at latest Open edX and Ubuntu 18.04
[12:46] <albert23> SamuelMarks: you can still download a 12.04 cloud image from http://cloud-images.ubuntu.com/precise/current/
[12:46] <tomreyn> !12.04
[12:46] <SamuelMarks> yeah I've downloaded it
[12:46]  * SamuelMarks is giving up and running a VM on his laotop
[12:48] <tomreyn> yes, you'd definitely want to do this in VMs.
[12:48] <SamuelMarks> Yeah it's more that I was trying to get it running on IBM Cloud; but even after converting it to qcow2 it still didn't work there
[12:57] <SamuelMarks> Hmm, lots of hash errors on the apt-get update
[12:57]  * SamuelMarks tries `sudo rm -rf /var/lib/apt/lists/*`
[12:59] <tomreyn> those archives probably no longer exist where it's looking for them
[13:00] <tomreyn> old-releases.ubuntu.com
[13:01] <tomreyn> actually, precise is still on archive.ubuntu.com
[13:05] <SamuelMarks> Mmmm yeah that worked, ok proceeding with the bootstrap; hopefully won't error
[13:10] <SamuelMarks> gpg keyserver receive failed.   Hmm, is pgp.mit.edu not around?
[13:11] <tomreyn> hopefully no more
[13:11] <tomreyn> unless they reinstalled it
[13:11] <tomreyn> there's keyserver.ubuntu.com
[13:12] <SamuelMarks> Hmm
[13:13] <tomreyn> nc -vz pgp.mit.edu 11371      suggests it's listening, though
[13:13]  * SamuelMarks is running this script https://github.com/edx/configuration/blob/open-release/eucalyptus.3/util/install/ansible-bootstrap.sh
[13:14] <SamuelMarks> Oh good, new error "key 69464050 not found on keyserver"
[19:59] <fretegi> good morning
[20:12] <fretegi> so i have an interesting issue...  colleague nuked the partition table on a hdd using parted on the wrong disk
[20:13] <fretegi> good thing is, the disk in question is just a part of a raid1 data array, not part of the OS disk..
[20:17] <fretegi> so system layout is 1 disk for OS, 2 disks for data in software raid1 using mdadm.  LVM for swap and /root on /dev/sda.  1 LVM group for data array.  so we destroyed the partition on 1 disk on the data array, but that seems to be preventing the server from booting, lvm errors
[21:20] <tomreyn> fretegi: is this solved, yet?
[21:20] <tomreyn> if not, can you still boot to recovery?
[21:33] <fretegi> tomreyn, i did get it solved, rebuilding the array as we speak, however i am curious why it wouldnt boot
[21:34] <fretegi> tomreyn, the affected vg was seperate from the VG that contains / and the vg's are on separate physical disks too
[21:34] <tomreyn> fretegi: i suspect you had some file system backed by LV(s) in fstab
[21:36] <tomreyn> * unavailable LV(s)
[21:36] <fretegi> oh yea both vg's has volumes that were auto mounted via fstab.  in fact that is exactly how i got the thing to boot.  i just #'d out the affected group, booted right up.  thankfully was raid1 was was able to just re-assemble the raid degraded, remount everything and re-add the affected disk to md0.  rebuildng as we speak
[21:36] <fretegi> so any unavailable LV could cause LVM to just panic altogether?
[21:37] <tomreyn> panic? no. fail to boot fully? yes, i think so.
[21:38] <tomreyn> i think you can mark mounts as optional in fstab, but then you'll give up on a good way to detect errors you need to fix.
[21:39] <fretegi> hmmm... i guess the initramfs may not like the unavail. filesystems
[21:39] <tomreyn> and you probably wouldn't want, as an example, logs to be written to the root file system rather than the separate /var/log file system, just because the latter failed to be mounted.
[21:40] <tomreyn> which ubuntu release is this aynways?
[21:40] <fretegi> yea thats a good pt.  fortunately this is a very simple server, i was able to thoroughly track down what that disk was doing almost immediately so with a little fiddling was able to solve it pretty quick.  but i just didnt expect the lack of boot
[21:40] <fretegi> tomreyn, good question... lemme check
[21:41] <fretegi> 16.04
[21:42] <PaulePanter> tomreyn: Thank you. BigBlueButton 2.2 unfortunately requires Ubuntu 16.04. BBB 2.3 is going to be based on Ubuntu 18.04.
[21:42]  * PaulePanter does not fully understand that design decision, but that’s the way it is.
[21:56] <tomreyn> fretegi: you should upgrade
[22:03] <tomreyn> PaulePanter: there are test builds for 18.04 now, if you'd like to try: https://github.com/bigbluebutton/bbb-install/issues/37#issuecomment-661347668
[22:04] <tomreyn> but they're certainly late on this.
[22:04] <fretegi> tomreyn, yea little old eh haha
[22:05] <tomreyn> 16.04 still receives free support, but just until april
[22:07] <fretegi> yea still, your right, should upgrade
[22:15] <Maik> tomreyn: unless ESM is used which adds another 3 years of security updates. One can use ESM for free up to three machines.
[22:17] <Maik> Ubuntu members get up to 50 machines by the way
[22:30] <tomreyn> Maik: for non-commercial use, yes. fretegi was talking about their "collegue", which makes me think commercial. but sure, they can buy.
[22:30] <tomreyn> or just upgrade. or both.
[22:59] <Maik> tomreyn: thanks for clarifying, i must have missed reading that. My bad.
