sudo apt-get update and
sudo apt-get upgrade gives me this result
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?
When I check Software Center it shows me 23 new updates available, but when I try to make update it never finish and all the time there is information about 23 new updates.
