Qt Tools don't run after installing Qt 6.8.0 with online installer

[Tom asso]

Installed Qt 6.8.0 on ubuntu 22.04.3 with online installer (upgraded from Qt 6.7.2).
I can no longer run qtcreator:

% Tools/QtCreator/bin/qtcreator
Tools/QtCreator/bin/qtcreator: /home/me/Qt6.8/Tools/QtCreator/bin/../lib/Qt/lib/libQt6Core.so.6: version `Qt_6.8' not found (required by /home/me/Qt6.8//6.8.0/gcc_64/lib/libQt6DBus.so.6)

What causes this error? Here is LD_LIBRARY_PATH:
/home/me/Qt6.8/6.8.0/gcc_64/lib

What am I missing?
Thanks!

Hi,

Just don't play with LD_LIBRARY_PATH unless you have very good reasons (this one is not).

Qt Creator is self contained and you are pointing it to a different version of Qt than the one it's bundled with.

If you modified that variable in your bashrc (or equivalent) you are also forcing all your system's Qt 6 applications to use that version of Qt rather than the one provided by your distribution which is not at good idea either.
