Package Management
Nala
Nala is a front-end for libapt-pkg. Specifically we interface using the python-apt api.
sudo nala fetch This command works similar to how most people use netselect and netselect-apt.
nala fetch will check if your distro is either Debian or Ubuntu.
Nala will then go get all the mirrors from the respective master list.
Once done we test the latency and score each mirror.
Nala will choose the fastest 3 mirrors (configurable) and write them to a file.
