Ubuntu / Debian
We have barely scratched the surface on package managers. We focused on using
apt which is a relatively recent wrapper over the older
apt-get package manager.
Links about the Ubuntu/Debian ecosystem of package managers:
- Ubuntu Package Search
- The underlying apt-get Package Manager Man Page
- The even further underlying Debian dpgk Package Manager Man Page
In addition to Debian based distros RedHat based distros are also very popular.
A great place to start with learning about RedHat package managers would be to start learning about the dnf Package Manager.
