I would personally upgrade to Ubuntu 22.04 LTS. Is there any reason you’re still on 18.04 LTS? glibc is not something that’s supposed to be upgraded by a user, it kind of just follows the distro versions.
That’s what I thought, I keep this version to not break things, I don’t want to spend hours finding and solving package incompatibilities. I think I will use godot 4.1 for now until there is something that I really need.
Ah. I forgot about the Flatpak! Considering flatpaks using glibc run on Alpine Linux, which does not even have glibc, it should work with an outdated version on the system.
Not supporting Ubuntu 18.04 is not a bug, it’s a decision.
Linux binaries can only support at most versions of glibc newer than the one they were compiled against. Godot 4.2 is using newer toolchains (GCC 13) and glibc (2.28), which is not supported by Ubuntu 18.04.
Ubuntu 18.04 is EOL since May 2023, so we don’t aim to support it.
