Aborting ltspI don't know how to mount /srv/ltsp/ubuntu-ltsp.img

hank7, I have some time now if you're around
18:39
<hank7>
awesome. Yes i have time
18:39
thank you
18:40
so i need to open epotes from my ltsp server and put that info you put earlier, correct?
18:46
i connected in epoptes
18:58
<alkisg>
hank7, all ok, you just needed to apt update ltsp
18:58
you had the old 19.12 one instead of the new 20.01
18:59
<hank7>
oh ok.. good to know. I will try booting up the diskless workstation once the current process is done and post results.
18:59
Thank you so much for your help. It is much appreciated.
19:00
ok thin client is booting up now
19:03
ok it gave the same error as before: Image doesnt exist /root/images/newubuntu-ltsp.img
19:04
ltsp command failed mount_img_src /root/images/newubuntu-ltsp.img /root
19:05
aborting ltsp, enable DEBUG_SHELL to troubleshoot
19:05
is it looking for the image in the wrong directory?

<alkisg>
hank7, try `sudo ltsp ipxe`
19:31
<hank7>
i did that and reboot thin client but same
19:31
well actually not same, different errors
19:33
keyerror: 999
19:34
<alkisg>
That keyerror doesn't sound like an ltsp error
19:34
Can you take a photo?
19:34
<hank7>
yes, where can i put photo for you to see?
19:35
<alkisg>
imgur.com
19:36
<hank7>
haha ok.. i thought maybe it can be through the irc.. ok
19:36
let me get a link

hank7, sounds like you have a broken passwd file, did you ever edit it manually?
19:40
run pwck etc on the server to check its integrity
19:41
and grpck
19:41
<hank7>
I have not edit it.
19:41
ok
19:42
<alkisg>
user 'nagios': no group 999
19:42
correct that, then run `ltsp initrd`, then reboot client
19:42
<hank7>
i used to have that application on this machine. ok ill look at that
19:48
<alkisg>
hank7, passwd can't have comments
19:48
OK let me fix it
19:49
<hank7>
oh ok i ran deluser nagios and it said no user
19:49
<alkisg>
Also, #www-data is wrong too
19:50
hank7, don't edit it now
19:50
let me fix it
19:50
hank7, ok try to boot the client now
19:53
<hank7>
Yay! I got a login screen.
19:53
thanks so much. This really should be a dedicated server and not other services.
19:53
runnign at the same time
19:58
<alkisg>
You're welcome :)
20:03
<hank7>
the desktop is slow. i suspect it is this old thin client though.. diskless workstation 1720
20:26
<alkisg>
The new ltsp doesn't support "thin clients", only "fat clients"
20:26
The specifications are the same as normal ubuntu installations
20:27
Core i3 etc should be fine
20:27
<hank7>
fat clients, meaning like a normal desktop.
20:27
ah ok
20:30
i got somehting unexpected for me. I'm thinking that this is how it works but I'm just ignorant/learning. On my ltsp server I have a user, erik. When I boot up the thin client and login as erik, I can see files that are on my desktop on the ltsp server. I was thinking that it got all that from the virtual machine image. For example, the user(s) I created on the virtual machine in virtualbox, i thought these were the users that were going to be presented to the
20:31
client.
20:32
<alkisg>
hank7, this is by design. Create users on the server. The VM is only the programs, not users nor home.
20:34
<hank7>
Ok. so to install programs, i'd need boot up the VM, install app, shutdown the VM, and run ltsp image myimage.img. Do i have that right?
20:34
<alkisg>
yes
20:36
<hank7>
can this be done whilst users are logged in to clients, or should they log off for admin to install apps?

<PanchoIIX>
Hello everyone, I have no idea what I did wrong. In a fresh OS installation (Ubuntu 19.10 and Uuntu MATE 18.04) I followed the steps from here https://ltsp.org/docs/installation/ (CHROOTLESS) The client goes directly to the iPXE boot menu and only Memory test and other but there isn't the image created to boot. Please any idea what am I doing
21:52
wrong? Thanks!
