Recently I was trying to install an application using the apt command on Ubuntu when I encountered the following error:
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?
In fact, there is a similar error you may see:
E: Could not get lock /var/lib/apt/lists/lock – open (11: Resource temporarily unavailable)
E: Unable to lock directory /var/lib/apt/lists/
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?
These errors are very similar to another common Ubuntu error, Unable to lock directory /var/cache/apt/archives/, and the interesting thing is that the fixes are similar as well.
This locking is done so that two processes don’t change the content at the same time as it may lead to unwarranted situation and a possible broken system.
Let’s see what steps can you take to fix this issue of ‘unable to lock administration directory’.
