We've been getting an error in our CI because some the Ubuntu 24.04
image in GitHub Actions doesn't have an updated package database:
```
E: Failed to fetch mirror+file:
pool/main/g/ghostscript/libgs-common_10.02.1%7edfsg1-0ubuntu7.4_all.deb
404 Not Found

E: Unable to fetch some archives, maybe run apt-get update
or try with --fix-missing?
```
Running `sudo apt-get update` before trying to install a package solves
the issue.
