E: Could not get lock /var/lib/dpkg/lock-frontend – … [Fix]
I’m hosting a few websites for some friends and clients which most of them are running on Ubuntu.
Once or twice a month I always go read logs remove cache and pull the patch if any.
The most common commands to pull those security updates I run are:
$ apt-get update $ apt-get upgrade $ apt-get dist-upgrade.
Sometimes I was distracted by my son or some chores so that I ended up losing the connection as I always use SSH.
Most of the time I got the error like this:
E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable) E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?
The easy fix is to remove the lock files that the dist-upgrade command has produced.
$ sudo rm /var/lib/apt/lists/lock $ sudo rm /var/cache/apt/archives/lock $ sudo rm /var/lib/dpkg/lock*
Then reconfigure the packages. Run in terminal:
sudo dpkg --configure -a sudo apt update
Then the problem should have been fixed!
