I installed and updated Ubuntu but I cant seem to install software. I tried the terminal and it says :
ugwyn@ugwyn-VGN-TX57GN-B:~$ sudo apt-get install flashplugin-installer [sudo] password for ugwyn: 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? ugwyn@ugwyn-VGN-TX57GN-B:~$
Am I doing something wrong?
