The Yubico Authenticator 7.0.0 does not work on RHEL 8 and derivatives

[hadrabap]

The Yubico Authenticator 7.0.0 does not work on RHEL 8 and derivatives Linux distribution due to failure of authenticator-helper.

The root cause is that helper/_internal/libpython3.12.so.1.0 is compiled on newer distribution with newer GLIBC.

[opc@sws yubico-authenticator-7.0.0-linux]$ ldd $( find . -type f \( -perm /a+x -o -name '*.so*' \) ) 2>&1 | grep -v '=>' | grep 'not found' 
./helper/_internal/libpython3.12.so.1.0: /lib64/libpthread.so.0: version `GLIBC_2.30' not found (required by ./helper/_internal/libpython3.12.so.1.0)
./helper/_internal/libpython3.12.so.1.0: /lib64/libm.so.6: version `GLIBC_2.29' not found (required by ./helper/_internal/libpython3.12.so.1.0)

To fix this, the provided binaries should be compiled at most on RHEL 8-like Linux distribution or any other still supported LTS glibc-based distro with glibc version <= 2.28 (e.g. Oracle Linux 7).

Based on this listening (Oracle Linux 7):

I suspect the Yubico Authenticator 7.0.0 is not build on RHEL 7-like distros, which is a shame, as it is currently the oldest supported LTS distro. Oracle Linux 7 is supported even longer. Another way how to handle versions of key components is to follow recommendations of VFX Reference Platform.

Hello, thank you for reporting the issue. I reproduced the error with CentOS 7 and tried some quick workarounds, such as default build of Yubico Authenticator from sources / installation of Flathub’s flatpak / rebuilt flatpak locally, none of which sadly works. I am taking this back to discuss with the team and will keep you informed.
