@liner wrong Qt version (5.10). After update on start error:

./qtcreator: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by /media/linuxer/HD500GB/QTAPI/Tools/QtCreator/bin/../lib/Qt/lib/libQt6Core.so.6)

JoeCFD

Check the version of libc to see if it matches the requirement. If not, do upgrade.
ldd --version /usr/lib/x86_64-linux-gnu/libc.so

liner

@JoeCFD: "... if it matches the requirement." What requirement? Where it is defined?

liner

The reason was in version Qt 5.10. After upgrading to 5.15.2, this problem has gone, but others appear.
Why I have this problem in connection with the "wrong version" is not clear. As well as the emergence of many new problems.
In general, the so-called "free software" is not so free. A lot is hidden from users.

stupidQt

I totally agree with you. Many problem in it and also there is no trusted solution.
