Hi, sorry to bother you guys, but is the app repo down? Updating the repo from the Ubuntu 18.04 guide just ends up with a 404 for [IP: 91.189.95.83 80].

<map7`>
can I have both i386 & amd64 ltsp images installed on my server and direct some older clients to the i386 image and 64bit clients to the amd64 image?
05:25
could this just be done through lts.conf?
05:29ricotz has joined IRC (ricotz!~ricotz@ubuntu/member/ricotz)
05:30
<alkisg>
map7`: for the first question yes, for the second, no, it needs to be done before lts.conf gets loaded, e.g. from dnsmasq.conf or boot.ipxe
05:30
And, without a question: why don't you use a single i386 image for all clients?
05:32
<map7`>
alkisg: that's what I do now (under Debian Jessie) but I want to install a more recent kernel than 3.16 for drivers for the Intel 620
05:32
<alkisg>
You can surely do that
05:33
<map7`>
and everytime I do this under the 32bit image it doesn't boot the latest kernel
05:33
<alkisg>
Why change the arch, instead of just installing a new kernel?
05:33
<map7`>
it still boots the old 3.16
05:33
<alkisg>
OK,let's fix that part then
05:33
Are you using a chroot?
05:33
<map7`>
i thought 32bit is being dropped from the kernel, is this true?
05:33
<alkisg>
No
05:33
<map7`>
yes I'm using chroot
05:34
I need kernel 4.9 for the new GPU
05:34
it's in backports
05:34
<alkisg>
My schools use ubuntu 18.04 32bit with 4.15 kernel
05:34
You can surely use that kernel then
05:34
<map7`>
ah cool
05:36
ok well I have cloned my server to a test rig which I can practice with
05:36
and redirected my DHCP to point to the test rig to boot thin clients
05:37
<alkisg>
Normally, you just install the new kernel to the chroot and run ltsp-update-image
05:37
<map7`>
yes I've tried this but it still boots the old kernel
05:37
<alkisg>
This will get you two kernels, both 3.x and 4.x; later on you can remove 3.x if you want to
05:37
So, at the point where you see any issues, ping me
05:37
To help you troubleshooting
05:38
<map7`>
ok cheers, I'll go through it on my testrig and let you know, thanks mate
05:38
<alkisg>
np
05:39
<map7`>
I have 'linux-image-4.9.0-0.bpo.3-686' or 'linux-image-4.9.0-0.bpo.3-686-pae' packages in backports
05:39
which one should I be installing?
05:40
<alkisg>
Well if ALL your clients have < 4 GB RAM, you could install the non-pae one, but in general, just go for the pae one
05:40
PAE allows clients to see more than 4 GB RAM for a tiny performance cost
05:41
<map7`>
ok, well the new thin client has 8GB or ram so I'll install pae, thanks

Hi Tono, what host are you talking about? The greek schools ppa, hosted by launchpad?
05:44
It works fine here
05:46
<Tono>
Running 'add-apt-repository --yes ppa:ts.sch.gr'
05:46
then 'apt update'
05:47
<alkisg>
Tono: can you paste the whole output?
05:47
Put it to pastebin, for both commands
05:47
!paste
05:47
<ltsp>
paste: To avoid channel flooding, please upload text longer than 3 lines to http://paste.debian.net. Don't forget to paste the resulting URL here.

05:49
<Tono>
http://paste.debian.net/1076628/ here's the first one
05:49
<alkisg>
Tono: cosmic
05:50
LTSP doesn't really support non-LTS Ubuntu releases
05:50
Use 18.04, bionic instead
05:50
<Tono>
Ah, that would make sense
05:51
<alkisg>
You could test without the PPA, but it would be an unsupported ltsp version, that doesn't receive updates etc
05:53
<Tono>
I actually tried that earlier, but installing in chroot mode ended with the installation ending abnormally.
05:54
E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/x/xorg-docs/xorg-docs-core_1.7.1-1.1_all.deb Undetermined Error [IP: 91.189.88.161 80]
05:54
was the final error
05:55
<alkisg>
You tried installing ltsp in cosmic without the ppa, and it failed?
05:55
That file does seem to be there, so it sounds like a temporary networking issue?
05:55
<Tono>
Yes
05:55
Hmm, I guess I'll try it again
05:56
<alkisg>
Tono: but I'd really advice against it
05:56
As an ltsp developer and the person maintaining ltsp in ubuntu... I say, avoid it :D
05:56
<Tono>
Hahaha
05:56
<alkisg>
Why do you want to test cosmic instead of bionic?
05:57
(which will actually get you an OLDER ltsp?)
05:57
<Tono>
Its just what my server was running, figured I give it shot
05:57
<alkisg>
Eeew, servers with non LTS versions?
05:57
Those are supported for 9 months only
05:57
Is your server disposable? :P
05:57
<Tono>
Pretty much disposable haha
05:58
<map7`>
alkisg: Ok I've installed the 4.9 kernel, done a ltsp-update-kernels and ltsp-update-image, then booted the thin client and when I check the 'uname -a' through the 'ltsp-localapps xterm' it shows as 3.16 still
05:58
<Tono>
I think I'll take the chance to move it to lts, but I was looking forward to 19.04..
05:58
<alkisg>
Tono: 19.04 will still have an older ltsp than 18.04 :)

06:00
<Tono>
Alkisig, I never really thought about newer versions having older versions of software, but it makes a lot of sense since theres less support...
06:00
<map7`>
pxelilnux.cfg/default https://pastebin.com/y4vkVYfY
06:01
The new kernel doesn't seem to be listed in the default grub menu
06:01
my mistake it is half way down
06:03
<alkisg>
map7`: strange, it's sorted below instead of on top. Temporarily, modify pxelinux.cfg/default manually, to put it as 'DEFAULT',
06:03
when you see that everything works, just remove the older kernels; it'll be first then as it'll be the only one

06:05
<alkisg>
Just modify lines 4 and 5
06:05
<map7`>
ok
06:06
is that it and just reboot my thin client?
06:07
<alkisg>
Yup
06:07
<map7`>
hmmm, I get the same result. The thin client booted 3.16.0-4-586
06:08
<alkisg>
Can I see?
06:08
!vnc-dide
06:08
<ltsp>
vnc-dide: To share your screen with me, run this: sudo apt-get --yes install x11vnc; x11vnc -connect srv1-dide.ioa.sch.gr - this is a reverse connection, it doesn't need port forwarding etc.
06:08
<alkisg>
(the server)
06:11
<map7`>
I'm logged in through x2goclient to the server isn't there a slightly different command I have to use?
06:11
<alkisg>
Add -noshm
06:11
x11vnc -noshm -connect srv1-dide.ioa.sch.gr
06:13
<map7`>
just one sec
06:19
alkisg: ok it's up
06:22
alkisg: I'm not running DHCP on that server
06:23
<alkisg>
map7`: try rebooting the client
06:23
You have tftpd-hpa with 2 tftp roots
06:23
One in /var/lib/tftpboot and one in /srv/tftp
06:23
Delete one of them. LTSP normally uses /var/lib/tftpboot
06:23
So you had to modify /srv/tftp/...pxelinux, not /var/lib...pxelinux
06:24
<map7`>
oh ok
06:24
just rebooting now
06:24
it's dropped me at BusyBox
06:24
Could not load neither overlayfs nor aufs

alkisg: I've got a VM PXE client so you can see it boot there
06:26
alkisg: in virt-manager
06:26
<alkisg>
map7`, I think debian has had some issues with nfs with the 4.x kernels
06:27
I think they were partially resolved later on with ltsp AND kernel updates
06:27
So I think debian has switched to nbd, to workaround that issue
06:27
I did try nfs a while ago with kernel 4.15 in ubuntu and i did push some ltsp changes to make it work,
06:27
<map7>
alkisg: Should I switch to nbd?
06:27
<alkisg>
but I'm not testing debian, vagrantc is...
06:28
Switching to nbd sounds like a good idea, yes
06:28
Although I'm worried about that overlay message
06:28
Aufs did get deprecated, but overlay should work fine since 5-6 years now
06:28
<map7>
Is it easy to switch to nbd?
06:29
<alkisg>
It should involve ltsp-update-image and ltsp-config nbd-server, but I really wouldn't want to spend time in troubleshooting old debian releases, so I'm not sure I'll be able to help you there
06:32
<map7>
alkisg: Should I give nbd a go?
06:32
<alkisg>
What are your options?
06:32
<map7>
this is just a test rig
06:32
<alkisg>
Ah sure then, go ahead

<map7>
alkisg: I booted my thin client and it now boots but it's still on 3.16
06:38
how do I check that it's booting through nbd?
06:39
<alkisg>
map7, cat /proc/cmdline
06:39
But every time you run ltsp-update-image, pxelinux/default get re-created
06:39
So you need to re-edit it
06:39
and select the 4.9 nbd entry from there
06:39
<map7`>
ok
06:41
<alkisg>
Remember to edit /srv/tftp, not /var/lib/tftpboot...
06:42
<map7`>
ah thanks
06:43
alkisg: I get the overlayfs message again
06:43
<alkisg>
Is there a newer ltsp in backports?
06:43
If not, maybe you can't use 4.x kernels in jessie, you'd need to ask vagrant
06:43
Ah maybe he's here, vagrantc? ^
06:49
<map7>
yes there is a more recent version of ltsp in backports
06:49
5.5.8
06:50
<alkisg>
OK, try that one
06:50
In the chroot, mostly
06:50
<map7>
ok, should I also install it on the server side?
06:50
<alkisg>
Generally, yes; in this case I'm not sure it matters

alkisg: Thanks again,
06:55
now should I remove the /srv/tftp directory

map7`, you'll also need to update your tftpd-hpa configuration for that
06:56

Hello LTSP world. I just updated my ltsp server to latest debian 9 upgrades, and my client displays go dark. To be specific, I get a login screen,
21:02
choose a window manager (XFCE was fine before), then the display goes dark, and there's nothing to do but reboot.
21:03
I can get a failsafe terminal connection. Where should I look for login information?
21:03
My problem is you all did too well with ltsp, it just works and it has been so long since I had to troubleshoot, I've forgotten where to start!
21:03
...and thanks in advance for suggestions.
21:04
FWIW, I upgraded the server. Then the ltsp installation via ltsp-chroot. Then ltsp-update-clients. Then a reboot. I might try another full system reboot.
21:10
...And problem solved with just the server reboot. We will probably be good for another 2 years or more of uptime... Thanks for listening!
21:10
Love LTSP.
