E: The package paradox-launcher-v2 needs to be reinstalled, but I can't find an archive for it.

And
$ dpkg -l | grep parado
iHR paradox-launcher-v2 2022.14 amd64 Paradox Launcher v2 - download and install your favourite games

I maaged to unblock dpkg by these steps:

sudo mv /var/lib/dpkg/info/<packagename>.* /tmp/
sudo dpkg --remove --force-remove-reinstreq <packagename>

But i'm still afraid to install paradox launcher!

Unless you have a real need for it, the Paradox launcher is not required to install or play Stellaris.

If you want a nice clean install of Stellaris on Debian, I strongly advise using ./play.it to convert your GOG installers into .deb packages.

Thanks! . I will try it.
