<aurele98>
hi everyone!
17:44
<alkisg>
Hello aurele98
17:45
<aurele98>
Do you guys have any clue why, when i'm trying to do a chroot from my powerPC, i got an error saying that i miss the "linux-image-powerpc" package ?
17:47
i searched and found linux-image-powerpc-smp but even with all packages updated and source changes it didnt worked so well
17:47
tbh i got the ambition to
17:48
sorry
17:49
to be honest my goal is to use the PPC as a thin client and the server would be a classic x64 architecture but in order to that i must do the chroot on the ppc first (if i'm reading well)

aurele98: good luck, not really well tested process doing PPC on x86

18:23
<aurele98>
yup, saw that :/
18:34adrianor1 is now known as adrianorg
18:43
<bennabiy>
alkisg: any reason why epoptes would all of a sudden stop working?
18:44
I guess for another time
18:44* bennabiy waves
18:44
<aurele98>
lel
18:51
<alkisg>
bennabiy: no reason, no
18:53
aurele98: can you install some linux directly on the ppc?
18:53
If yes, then just install ltsp-client in it, and transfer the result to the server
18:53
No need to chroot then...
19:00lucascastro has left IRC (lucascastro!~lucas@201.182.221.14, Ping timeout: 240 seconds)
19:03
<aurele98>
yes of course, forgot to say that i'm on lubuntu ppc
19:04
that's the whole problem
19:04
to do that i need the now famous "linux-image-powerpc"
19:05
<vagrantc>
any linux-image will do, as long as it runs on the hardware you want to support
19:05
you don't need to install linux-image-powerpc specifically
19:06
if you insist on using a chroot, you can specify which linux-image package to use with --kernel-package, if i remember correctly
19:06
<aurele98>
well isnt ltsp-build-client isnt a form of chroot ?
19:07
i thinki'm tired as hell guys
19:07
yes i am
19:11
i'll try something and inform you of what happened
19:21
<vagrantc>
aurele98: you could do an ltsp-pnp method:
19:21
!ltsp-pnp | echo aurele98
19:21
<ltsp`>
aurele98 ltsp-pnp: ltsp-pnp is the recommented method to install and maintain LTSP for "usual" setups. Since it doesn't involve chroots, it requires little to no command line to maintain it. It automatically supports both thin and fat ltsp clients. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp
19:21
<alkisg>
aurele98: I don't understand, if you're in lubuntu ppc you already have a kernel
19:21
You don't need a new one...
19:22
Does ltsp-client force you to install something that you don't already have installed?
19:22
<aurele98>
no
19:22
<vagrantc>
aurele98: in general, we're discouraging ltsp-build-client and recommending ltsp-pnp
19:22
<aurele98>
and that's weird
19:22
<alkisg>
What's the output of `uname -a; ls /boot` in your ppcclient?
19:22
<aurele98>
ok
19:23
sry i'm trying pnp rn brb
19:24
<alkisg>
ltsp-pnp is suitable when you want the ppc to be the server
19:24
But you want an amd64 server
19:24
<aurele98>
u got it
19:24
<alkisg>
So in your case you just need to install ltsp-client in the ppc client, and transfer the result
19:24
<vagrantc>
you can build the image on the PPC hardware, and copy the resulting image over to the server
19:25
<aurele98>
yeah but it keeps crashing to that kernel thing
19:25
i dont get it
19:25
<vagrantc>
what keeps crashing?
19:25
<alkisg>
Paste specific commands and their whole output
19:25
<aurele98>
i got linux image powerpc snp
19:25
<alkisg>
Not just "it crashes", that doesn't help
19:26

vagrantc: recent nbd bug, affecting the bpo kernels in stretch, and expected solution: https://github.com/NetworkBlockDevice/nbd/issues/57
19:27
(and also the stock kernels in 16.04)
19:27
<aurele98>
oh i forgot i'm french so if there's some french tell me which sentence
19:28
<alkisg>
Use "export LANG=C.UTF-8" before
19:28
Then the messages will be in English
19:28
<aurele98>
k
19:29
thx a lot guys means really a lot
19:30
i'm saying that now cause u know, ppcs are slow
19:30
<vagrantc>
aurele98: could you paste the command you're running while we wait?

I think we both were telling you: "don't use ltsp-build-client"
19:34* alkisg gives up :)
19:35

fuck me
19:36aurele98butfaste has joined IRC (aurele98butfaste!4ec0c126@gateway/web/freenode/ip.78.192.193.38)
19:36
<aurele98butfaste>
ok
19:37
now i cant miss a message
19:37
<vagrantc>
you just need to install the "ltsp-client" package on the PPC machine, and run "ltsp-update-image --cleanup /"
19:37
do not use ltsp-build-client
19:37
<aurele98>
ok
19:37
fuck
19:37
<alkisg>
!language
19:37
<ltsp`>
Error: "language" is not a valid command.
19:37
<vagrantc>
then, you can copy the /opt/ltsp/images/*.img to the server
19:37
that's the short of it... no idea if it will work. :)
19:38
<aurele98>
i heard this idea before
19:38
<alkisg>
It'll need an ssh keys update
19:38
<aurele98>
but why did i ran that stupid command
19:38
<vagrantc>
didn't we create a way to do that at runtime?
19:38
aurele98: ctrl-c should get you out of it
19:38
<aurele98>
ofc i know why cause it worked for a guy
19:39
boy i feel like i'm the dumbest guy alive
19:40
<alkisg>
vagrantc: not really, except for INIT_COMMAND_xx="ssh-keyscan server > /etc/ssh/known_hosts"...
19:40
Ah, and some directive to completely ignore them
19:40
LDM_OPTIONS=-o stricthostkeycheck etc
19:43
<aurele98>
should i be concerned if it skips etherboot images / PXE configuration ?
19:46
<alkisg>
no
19:47
<aurele98>
ok thanks

alkisg: we could append a cpio.gz with the initramfs that includes some extra stuff
19:49
aurele98butfaste: try /nick NAME
19:49
<aurele98butfaste>
thanks, forgort all of my IRC exp
19:50aurele98butfaste is now known as aurele98
19:50
<alkisg>
vagrantc: i have an example implementation of booting ltsp with just that cpio.gz :)
19:50
No custom initrd at all...
19:50
<vagrantc>
alkisg: how do you deliver the cpio.gz ?
19:53
<alkisg>
2 pxelinux lines
19:57
<vagrantc>
that's pxelinux-specific
19:57
obviously...
19:58
i've been experimenting a bit with appending a cpio.gz to the initramfs ... so the only custom thing is cat initrd.img cpio.gz > initrd-with-extra-fun.img
19:59
that works with any standard debian kernel for the last 5 years or so
20:00
then any bootloader that supports initramfs supports that method
20:00
but yes, i'm getting tempted by one of those two approaches

The raspberry bootloader netbooting code tries to imitate parsing/executing pxelinux.cfg
20:05
We could file a bug in uboot too...
