I tried to uninstall comodo but it is showing the following errors:
anurag@ubuntu:~$ sudo apt-get --purge remove cav-linux
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?
anurag@ubuntu:~$
What can I do about this?
