Ubuntu sometimes doesn't boot

[vince]

Using ubuntu 11.10 kernel 3.15 (also had the same problem with previous kernels)
A lot of the times I try to boot ubuntu,
after the grub Instead of the login screen I get this screen instead http://i748.photobucket.com/albums/xx130/sirvinniei/IMG_0092.jpg
(the line about plymouth says not connected to plymouth)
usually rebooting it (sometimes more than one time) solves the problem

The console output also shows that the hostname job fails on boot, which is abnormal; this job simply calls the 'hostname' command, which is located on the root partition and is a required package. So your system seems to be in an inconsistent state. Please install the debsums tool with 'sudo apt-get install debsums' and post the output of 'debsums -s' from this system.

hereś the teminal oputput of the thing you said,
thanks for the quick reaction

[Steve Langasek (vorlon)]

ok; this shows a lot of missing files but apparently nothing outside of /usr/share, so this doesn't explain the failures during early boot.

what does 'dpkg -l hostname' show?

Ok, one more command. Please show the output of:

$ sudo debsums -s -e

Oh, interesting. Not the kind of problem I *expected* to find, but it certainly explains why the hostname job is failing.

Hostnames are not allowed to contain spaces. Could you please edit /etc/hostname and /etc/hosts to replace "ultimo sapientiae" with "ultimo-sapientiae", and see if that fixes your problems?

[vince (vincent-typerrr)]

Just changed the name of my pc,
will this fix my problems?

thanks for all your help,
I've asked this question on many different forums and I never got a real awnser

sincere, Vince

I don't know. It will fix *one* problem on your system, and it may fix
others. Please test and report back.
