--- Comment #6 from Urs Fleisch <uflei...@users.sourceforge.net> --- I have now set up a virtual box with a fresh install of Linux Mint 20, updated the default packages and then installed kid3-qt from the PPA. Unfortunately, I am still not able to reproduce the issue, i.e. everything is working correctly. Searching the web for similar issues, some people reported similar messages with qmake, and the solution seems to be to either install the "qt5-default" package or set the version explicitly ("man qtchooser", the error message "could not find a Qt installation of" actually comes from qtchooser). I personally have set the environment variable QT_SELECT to 5 to tell Qt which version to use. To have this envionment variable always available I have put a line "export QT_SELECT=5" into ~/.xsessionrc and a line "QT_SELECT=5" into ~/.pam_environment. Both these files have to be executable and will only take effect when logging in again. -- You are receiving this mail because: You are watching all bug changes.
