Hi!

I got the following error:

Hi,

Thanks for reporting this. The program should have stopped after that first error message, I will fix it.

That error is genuine though: you can't natively install Ubuntu packages (which uses APT) on Arch Linux (which uses Pacman). You can however use the other unpackers, for example reproducing the environment in a Docker container or a virtual machine.
