When I try to install through my terminal I get this error:
enyel@Alexandria:~$ sudo apt-get unsettings
E: Invalid operation unsettings
enyel@Alexandria:~$ sudo apt-get install unsettings
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?
I already added the PPA and updated it, can anyone help?
