To check which version of glibc you have, run ldd --version in the terminal.

2.31 was released on 2020-02-01.

That's surprisingly new. Wonder what causes the incompatibility

The changelog for 2.31 is here:

https://sourceware.org/legacy-ml/libc-announce/2020/msg00001.html

Latest version of glibc is 2.41, released 2025-01-30. That puts 2.31 at least 10 releases behind. That version is quite outdated. There are numerous security and bug fixes in 2.31 alone, with each newer release also fixing some as well.

This might be the reason for requiring glibc 2.31 and newer:

Security related changes:

CVE-2019-19126: ld.so failed to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program. Reported by Marcin Kościelnicki.
