Yes, I'm aware that KaOS is not Arch based and that I really should not install pre-built packages from other sources. As I said earlier, I did that because the packages were not currently available in KaOS. All foreign packages are now locally re-built from their PKGBUILD files and all seems to be well.
However, KCP guide https://kaosx.us/docs/kcp/ says that "If you can find working PKGBUILDs elsewhere, use them." so I do have to say I am a bit conflicted, since that's essentially what I did... Anyway, I'll keep any self-caused troubles out of the forum, and they weren't the issue here either.
What do you think about the Octopi SysInfo behavior? Would you like me to reproduce it with a clean install?
