I’ve never heard of alien before, but you can install deb packages with dpkg in void. I wouldn’t recommend it, of course. But, i install a decent amount of stuff void does not have this way.
Just install dpkg from the repos, then i’m pretty sure you just have to do the following to get it up and running:
If youre going to do this definitely do not install any libraries from debian. Or anything important for that matter.
dpkg will complain during a package install because it does not know what xbps has installed, but most debian packages will install with the “–force-all” flag. You’ll have to manually resolve dependencies for libraries from the void repos, if you dont want to break your system that is.
And i’m thinking probably close to nobody here will help you out with issues with debian packages on void, Its a better idea to submit new packages and templates to the void repos.
