Your SSH connection get cut or timeout while you were either updating or installing an application with apt-get? Don’t worry, these easy steps will get you out of trouble!
1. Try to run your command again :
root@server:~# apt-get install <app_name>
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?
2. Okay, the process is locked, find out the process ID :
ps -A | grep apt-get
0000 pts/0 00:00:00 apt-get
3. KILL IT, the hard way :
kill -9 <0000>
(replace <0000> with the the process ID)
4. Run your command again :
root@server:~# apt-get install <app_name>
E: dpkg was interrupted, you must manually run ‘sudo dpkg –configure -a’ to correct the problem.
Just do :
sudo dpkg –configure -a
