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? >Which version of isc-dhcp-client is installed? Versión: 4.1.1-P1-17 cheers
