"Authentication failure" at console

Could you try running Debug, Live, and Text-Only mode, and give me approximately what it says?

I'll try to figure out if I can capture the console output. There's a lot of messages and they seem like a working Ubuntu boot log.

I've recorded the screen in debug and text only modes. The resulting video format is QuickTime's default one; if you are not able to watch them, don't hesitate to ask me to convert them to the format that suits you best.

I were changing consoles to see different outputs (ALT-F1/F2/F3...F7) that's why it jumps screens in the middle of the videos.

Files are 8MB each.

Hope it helps,

The debug.mov is completely gibberish for me, but the text-only one shows this: "sudo: unknown user custom".
Could you give me the output of running relinux to create the ISO?

BTW, If you didn't see, it also showed: "Starting LightDM Display Manager ... [FAIL]". Did you install lightdm?

Sorry for the delay.

The output of "sudo relinux iso relinux.conf" is:

/home/relinux/ubu-02.iso is generated. It is recommended to run it inside a virtual machine before you release it.

The size of /home/relinux/ubu-02.iso is 852M
You will need to burn a DVD/USB/Blu-Ray disk instead of a CD.

It is recommended to run 'sudo relinux clean' (without quotes) once you have burned and tested ubu-02.iso
It will not delete ubu-02.iso or ubu-02.iso.md5

Is it OK if we suspend this question until relinux 0.4? It might fix it, and if it doesn't, it will give a log file, so that I can further examine your problem.
Just make sure that lightdm is installed first.

Regarding LightDM, I did uninstall it. My Ubuntu is text only, I hope it doesn't interfere with Relinux. (It's an Ubuntu 11.10 desktop, not server).
BTW, I'm using Relinux 0.3.0a2. I've modified the relinux shell script in the exclude section and commented the "userdel" invocation because it deletes a legit user name (the Roundup bug tracker install the "roundup" user with 999 as its userid).

When you mentioned the "custom" user, I went through the conf file and looked at "/home/dummysys/etc/passwd" file. There is no "custom" there, nor a couple of entries that I'd rather keep so some init.d processes don't fail at startup. These couple of users have userid 1000 and 1001.

I can wait, sure.
My only objection about installing LightDM is that I'd rather have it disabled on init. Is that configuration compatible with Relinux?

Did I read this correctly: "the Roundup bug tracker install the "roundup" user with 999 as its userid"?
That's your problem! You need to change the userid to something else, less than 999. 999 is reserved for Casper, and if it exists on the CD, it will crash, just like yours did. Also, if you want to remove lightdm, you should remove GDM also, as I think it is installed for some reason on your system.

Yup. That's right. The roundup user was created by, as far as I can remember, its installer with the userid 999.

I'm sorry I wasn't aware of that conflict. I'll change its userid (reverting the changes in the relinux script).

BTW, this is the output of "dpkg -l gdm lightdm". Both are reported as removed, but there are config files around there as it seems.

hernan@ubu-02:~$ dpkg -l gdm lightdm
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name Version Description
+++-===================-===================-======================================================
rc gdm 3.0.4-0ubuntu11 GNOME Display Manager
rc lightdm 1.0.1-0ubuntu6 Display Manager

Try this:

sudo apt-get install lightdm gdm; sudo apt-get purge lightdm gdm

That should fix the lightdm/gdm problem. It will simply install them, then it will purge them (with the configuration files).

Thanks for the suggestion about purge, that removed them as you told me.

Regarding the "Authentication failure" error I'm afraid things haven't worked out.
I've changed the roundup's uid to avoid conflicts and chowned everything accordingly.

When booting the live cd it still shows that the "custom" user is not defined.
It still shows the "sudo: unknown user custom" message.
That's a bit weird because I changed the LIVEUSER config to point to "hernan", and later confirmed that the "hernan" entry
appears in /home/relinux/dummysys/etc/passwd and in /home/relinux/dummysys/etc/casper.conf

I'll try again by leaving LIVEUSER="custom" and adding the "custom" user to the Ubuntu.

Anyway, I think there's a bug in the relinux script, that might be related or not to this problem.
Two lines above ". $WORKDIR/cleantmpusers" there's a grep that look for users ids from 599 to 999 to remove them later. I think it's a bit too much. Let me know if you want me to file a bug report.

Well, make sure that your user's ID is 598 or less.

> Well, make sure that your user's ID is 598 or less.

Heh... Ok, I can live with that.

Regrettably my last intent didn't succeed either. While it doesn't show "sudo: unknown user custom" error message, it keeps reporting the "Authentication failure" in ALT/F1-F6.

I leave it now as is and I'll wait for the 0.4 release. Unless, of course, you come out with some other suggestion.

Regards,
Hernán.

Yeah, 0.4 should fix it

I want to add, that I'm using relinux for making Ubuntu for schools, and I found that when I'm making relinux with Ubuntu, everything is ok, but when I do relinux with KDE, in ISO there is a problem with creating LiveCD user. I found that I must not copy $HOME to skel in KDE, then everything is ok.
Maybe this will help you.

So copying $HOME to skel in Ubuntu works fine, but not in Kubuntu?

Yes,
I found that directory $HOME/.kde is the problem, when I copy it to
skel, then in starting Live CD there is an error somewere in the
scripts:
groupadd: error creating `groupdel user`
or something similar; I dont' remember exactly, because when I realize
that .kde is the problem, I just not copy it.

But if you want, I will try today and post exactly error and place in
the sripts.
