    Status: Open => Answered

marcobra (Marco Braida) proposed the following answer:
The message:

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?

is caused because another program that uses the package system is
running. Make sure you're not already running Synaptic or apt-get in the
background.

Also, the system periodically checks for updates. While doing this, it
triggers the lock that you're experiencing. Within ten minutes, it
should have finished.

If you still receive the message, you can try an assortment of these
commands to try and get rid of the locks:

sudo killall synaptic
sudo killall apt-get
sudo killall dpkg

or you can also reboot your pc...

Thank you
