==========================================================

For example, the post required from you could look similar to this:

[weremouse at moonstudio ~]$ sudo rm /var/cache/apt/archives/ligbm*
rm: cannot remove ‘/var/cache/apt/archives/ligbm*’: No such file or directory
[weremouse at moonstudio ~]$ sudo apt-get install --reinstall libgbm1
