Yeah the GLIBC thing is an issue with Debian based distros atm, iirc they are on the version 2.35 and the one that PyQt6 needs is the 2.36, the current version on Arch (my system) is 2.40, honestly i’m quite surprised that it’s that outdated.
if you do the command “ldd –version” in the terminal you should see your current version (Ex. ldd (GNU libc) 2.40).
