Bug#660558: general: hostname changed to unknownXXXXXX after upgrading packages

[Iker Salmón San Millán <ikerssm@gmail.com>]

I found that after upgrading executing sudo it responded sudo: unable to resolv host unknownXXXXX, so i looked into /etc/hosts and i found it changed but the problem is i did already corrected changing hostname with hostname binary, i didn't look into the other diles but my terminal was like this:

myusername@unknownXXXXXX:-$ (wehere XXXX were random numbers and letters)
instead of
myusername@desktop:-$

And i didn't attemp to reboot

But i have another computer without upgading yet to try to reproduce the bug but i will only have acces to it the next 24 hours.

Please attach the files /etc/hostname /etc/hosts /etc/nsswitch.conf
I've already backed up those archives before atemting upgrading to send after/before files, anything else to backup?
