Linux->> UBuntu->> Could not get Lock/var/lib/dpkg/lock-open (11:resource temporarily unavailable)

This error message occurred today when installing SSH with the Apt-get directory under Ubuntu 14.04. Find out what might be the cause.

First, APT acts as a software update mechanism that locks the apt database every time it runs. When the above error message occurs, you should first find out which process is running the apt-get or APT command, such as system updates.

There are many ways to solve this problem.

First of all, you did not find out exactly which process is using the APT command, then you should restart the machine should be no problem. You can find filters by keyword in the current process of the system

PS grep Apt

Kill Processnumber

Finally, it's not going to erase the lock.

sudo RM /var/lib/apt/lists/lock

sudo RM /var/cache/apt/archives/lock

So the first thing I think about is the system update.

Unable to lock the administration directory (/var/lib/dpkg/) is another process using it?
