Здравствуйте!
После обновления траблы с Qt Creator:

:-1: error: The Qt version is invalid: qmake does not exist or is not executable
:-1: error: The qmake command "/usr/lib/qt/bin/qmake" was not found or is not executable.

Попробовал решение:
ln -s /usr/lib/qt4/bin/qmake /usr/lib/qt/bin/qmake

Итог:

19:49:01: Configuration is faulty. Check the Issues view for details.
Error while building/deploying project tohovk (kit: Desktop)
When executing step "qmake"

Подскажите, куда копать, плс. Или как откатиться
