/usr/local/webots/bin/webots-bin: error while loading shared libraries: libQt6Core.so.6: cannot open shared object file: No such file or directory about webots-docker

[abdul-mannan-khan]

I fixed this problem. I solved it by including following command:

strip --remove-section=.note.ABI-tag /usr/local/webots/lib/webots/libQt6Core.so.6

I got to know about this command from here.

For reference, I am including the whole container file here below:
