Occasionally, when I try to install an update or install software via the console using apt-get, something goes wrong. To date, I have never had the failure of a package to install ruin my system. However, it isn’t uncommon after such an incident to get an error the next time I run apt-get. The easiest way to fix apt-get is to run the following command:
sudo dpkg --configure -a
The above command is the replacement for the old command in Debian-based distributions:
sudo dpkg-reconfigure --all
Almost every time I have run into an apt-get error, the above command has been able to solve the problem. It’s a useful command to have on hand if you’re running a Debian-based Linux distribution (like Kubuntu, my distribution of choice).
