Cross on linux mint 21.2 fails with GLIBC_2.25' not found


I try to crosscompile my old project on my fresh installed linux mint. But I get this error:

5 Month ago everything worked on my old ubuntu. Now I have no clue what to do to fix this problem.

Any help apprecciated,

Do you have the build tools for that target installed? You probably need the package gcc-arm-linux-gnueabihf and libc6-dev-armhf-cross.

I thought with cross I don't need the build tools. Ok, but now I installed the tools but I see still the same error.

Looks like something weird is going on with the ring build script? You might want to ask the ring maintainers.

Some days and reboots later it works. No idea why.
