Então me disseram que sudo apt-get remove software-center seria usado para remover o software-center, e então eu reinstalaria. Bem, toda vez que eu tento removê-lo eu entendo isso:
lacy@lacy:~$ sudo apt-get remove software-center
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
