I updated an old centrino-notebook after Ubuntu 9.10 with 12.04 - now sudo seem to be broken, because after sudo <whatever> I get the error message:
```
sudo: unable to initialize PAM: No such file or directory
```
In /var/log there seem to be no pam*.log file any more.

I cannot use sudo command for to change permissions of /etc files.

  I don't recognise pam*.log, but try /var/log/auth.log for more information on what's going on. It looks like some PAM package or other has failed to upgrade; the best way to fix this will involve booting in single-user mode.

  You may have to do a password recovery.... If this was a fresh install of 12.04, you might want to try again.

thanks for quick answer. I knew that in /etc is to create the file common-session-noninteractive but I cannot get into single-user-mode with shift-key ? shift-key is "dead" on this installation ?

/etc - files can be created or modified only as root or as sudo, but I am excluded from sudo ...

try with pkexec

apparently package-failure while update from 9.10 to 12.04 - so need simply to reinstall ... but how ?

boot with live cd and make a file
