Hello,

i am trying to upgrade my aptitude (i mean "sudo aptitude upgrade") ! but i get an error with a resource taken by another process.

i typed ps -e and killed one process ("update-agent" i think), but it was not the one.

i can't remember the command line with grep to identify which process is holding the hand of that file.

the file is /var/lib/dpkg/lock

can i find the one using grep and something ?

thanks.
