Same here when I have only installed the package "qt5-default". Mine was caused by missing packages.
You can search for a missing file like this: $ apt-file search /usr/lib/i386-linux-gnu/qt5/bin/assistant qttools5-dev-tools: /usr/lib/i386-linux-gnu/qt5/bin/assistant After installing the above package the problem about the missing file went away. I still needed one more package to be able to run assistant: Error reading collection file '/home/<username>/.local/share/QtProject/Assistant/qthelpcollection_5.0.1.qhc': Cannot load sqlite database driver!. This could be solved by installing "libqt5sql5-sqlite". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1155861 Title: qtchooser exits with error message not changing qt version To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtchooser/+bug/1155861/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
