@RL_Dane not sure what cpio is.
It's just two tar files, with content you need to put in your own opt, usr/bin/share/etc.. I've done this gymnastics 10+ at this point, and it's the first time that the application actually opens on the other end.
Usually you just end up cleaning up the mess you've made all over the place by hand-

Ah, ok. cpio is an archive format like tar, but I've never used it directly.
If deb files are just tarballs, then it must be rpm that uses the cpio format. I forget which -- I read it somewhere 20 years ago 😁
