Its a vps with only 1 instal of isp config for running few website so i think its a single user server.
I did update debian lenny to squeeze with a tutorial from howtoforge.
Press g and the list shows which packages need your attention. Fix any packages in the action list, until the message says:

After that debian updated well i suppose
I am a real command line rooki...
By the way thanks for helping
