<soroch>
Hi. I installed LTSP on server Debian. And i want to install distribution Ubuntu on think client. How do it?
14:57ben_roose has joined IRC (ben_roose!~roose@roose.cs.wichita.edu)
15:05
<sbalneav>
soroch: With difficulty.
15:06
<alkisg>
soroch: start with this for your first ltsp installation:
15:06
!ltsp-pnp
15:06
<ltsp`>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
15:06* ogra_ prefers to do it with coffee and cake
15:06
<sbalneav>
I'd make the chroot on a ubuntu server, and copy it over if I was going to try that. Or what alkisg says :D
15:06
Or definitely what ogra_ says
15:06
<ogra_>
:D
15:07
<alkisg>
Hmmm cooffee... nice idea, +1

then, distributive on server = distributive on thin client?

soroch: no, we only advice it because it's easier

16:44
<sophiee>
does anyone know where I can find a minimum file system just to run bash?
16:45
or what is needed for a minimum file system just to run bash?
16:45
<alkisg>
sophiee: not related to ltsp?
16:46
What is your operating system currently?
16:46
<sophiee>
it is linux mint - i just thought there might be some documentation on this
16:46
<alkisg>
sophiee: you already have bash
16:46
Just open a terminal, bash is there
16:47
<sophiee>
yeah I have - i need to create a new file system for a client and I need to include what is needed to run bash
16:47
im doing a thin client project :)
16:47
<alkisg>
A thin client project without ltsp?
16:47
How is the client going to boot?
16:47
From local disk?
16:47
<sophiee>
from a server using DHCP and PXE

16:48
<alkisg>
And you don't want the client to do anything else except run bash?
16:48eu^1191017726 has left IRC (eu^1191017726!770ab11a@gateway/web/freenode/ip.119.10.177.26, Client Quit)
16:48
<sophiee>
yeah that is all I need for now
16:48
<alkisg>
What's wrong with using ltsp direclty?
16:48
E.g. this:
16:48
!ltsp-pnp
16:48
<ltsp`>
ltsp-pnp: ltsp-pnp is an alternative (upstream) method to maintain LTSP installations for thin and fat clients that doesn't involve chroots: https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
16:48vagrantc has joined IRC (vagrantc!~vagrant@unaffiliated/vagrantc)
16:48
<alkisg>
That basically means that you run a few commands on your linux mint serverand the client will be ready
16:49
It will even support both thin and fat clients (fat means they're using their own cpu to run programs, but are still diskless)
16:49
...you should have your client ready in about 20 minutes that way
16:50
<sophiee>
ok i was hoping to configure my own with a custom file system
16:50
that is handy though
16:50
<alkisg>
You can run ltsp-build-client
16:50
This will generate a minimal chroot, with bash and a few other text mode stuff
16:50
And xorg, to be able to function as a thin client
16:50
But it's the old way to do things :D
16:51
<sophiee>
ok i might give it a try!
16:51
thanks!
16:51
<alkisg>
Start with ltsp-pnp to see the current state of things
16:52
Then, if you see that you don't like something, *then* try alternatives
16:53
<sophiee>
ok will do thank you

Problem not strictly related to ltsp: school has bought a multifucntion HP Color Laser Jet M477 or something like that, and has ltsp on (k)ubuntu 14.04. I need hplip >= 3.15, that is NOT in 14.04. I've searched for hilip backports but found nothing
20:41
seems that the only way is to upgrade the ltsp server to 16.04... :(
20:41
(I've not yet tested Kubuntu with 16.04 ltsp)
20:42
anyone faced this issues and solved differently?
20:42
And if I have to upgrade to 16.04, better backup /home and install 16.04 from scratch?
20:45
<alkisg>
markit: although you could search for a newer hplip, it sounds like a good time to upgrade to 16.04
20:45
It should be possible with just a "do-release-upgrade", without reinstalling anything
20:45
<markit>
alkisg: usually that way is very slow and leaves a lot of crap around, no?
20:46
alkisg: btw, hi, I'm happy to see you :)
20:46
<alkisg>
:)
20:46
markit: no, it shouldn't be very different to a new installation
20:46
Slow, yes, it'll need a couple of hours
20:46
But isn't that faster than reinstall and configuring everything?
20:47
Depending on how much you configure things after an installation...
20:47
<markit>
alkisg: maybe because I usually use the "kde backports" repost, in the past often the process stalled / aborted / lasted a HUGE time
20:47
<alkisg>
Well it shouldn't hurt to try if you plan to reinstall anyway
20:48
<markit>
alkisg: sure if you tell me so :)
20:48
<alkisg>
About newer versions, some times you can download them from packages.ubuntu.com => a newer ubuntu series than the one you have
20:48
but you need to check the dependencies first
20:49
Because it's possible that they have unmet dependencies that are only there in 16.04...
20:49
<markit>
any trouble specific with ltsp? btw, I have some in that school, some clients stuck at boot at a certain point, and sometime they keep booting if I in the meanwhile turn on one more client
20:49
let me take the cell phone with the photo of the screen and write here back the last message
20:50
at time 8 there is "nbd0: unknown partition table"
20:51
ad time 22 randome: noblocking pool is initialized
20:51
<alkisg>
That's normal, ltsp images don't have partitions
20:51
<markit>
then nothing more
20:51
<alkisg>
Normal too, just an info message, no error there
20:51
Upload the photo?
20:51
And what then, it stucks there?
20:51
<markit>
yes
20:52
but happend that if I turn on another client, the it "resumes" (continues from there)
20:52
I use dnsmasq if it counts, and a very "underpowered" server
20:52
<alkisg>
That doesn't make a lot of senses... :D
20:52
!quiet-splash
20:52
<ltsp`>
quiet-splash: to disable the splash screen in Ubuntu, in order to see any boot error messages, run sudo gedit /var/lib/tftpboot/ltsp/i386/pxelinux.cfg/default and remove quiet splash plymouth:force-splash vt.handoff=7
20:53
<alkisg>
Try to remove quiet-splash, and take /upload a photo of the boot process till there
20:53
<markit>
I can't now, I've their server here at home but just one client PC, probably does not happen right now
20:54
I have 9 clients there, and just one -two sometime do this (more or less random)
20:54
<alkisg>
Can you upload your existing photo?
20:54
<markit>
I was surprised, as I told, that turning on the client nearbie resumed the process
20:55
yes, let me download from the cell pone and then ask you where and how upload ;P
20:55
I could send you through gmail?
20:56
<alkisg>
If you google for "image upload", there are thousands of sites for that, similar to pastebin
20:56
postimage.io came first in google
20:57
<markit>
the real question were "ask you YOUR preferred way to have it uploaded" ;P
20:57
s/were/should have been
20:57
<alkisg>
I don't have one :)
20:57
Any link that will show the photo is fine for me
21:01
<markit>
https://postimg.org/image/emqzg5w83/
21:02
better
21:02
https://s29.postimg.org/a0uv7tap3/ltsp_client.jpg
21:02
(direct link)
21:03
<alkisg>
Hmm yeah I don't see anything wrong there
21:03
If it happens again, wait a bit, then boot another client so that the first one continues,
21:03
and at that time, get the syslog and the dmesg of the client
21:05
<markit>
ok, thanks a lot
21:05
time for dist-upgrade now :)
21:06
<alkisg>
:)
21:06
Good luck!
21:13
<markit>
alkisg: btw, in ltsp-pnp there still is the constrain that the server should have nostname "server" (AFAIR, is a ltsp constrain)
21:13
(also if my server don't have that name and everything seems to work anyway)
21:14
<alkisg>
markit, no, that was an issue with cups, i solved it years ago...
21:16
(and it was not an issue with ltsp-pnp... but with ltsp/cups in general)
21:22
<markit>
last: do-release-upgrade -m desktop or simply do-release-upgrade ?
21:28
I'm going with # do-release-upgrade

mmm problems since kde-desktop package is no more present in 16.04, plasma-desktop is the right one
23:55
now aptitude -f install wants to remove a TON of necessary packages
