Hi there. I’m stuck with the build instructions. It seems there is no longer a qt5-default package on Debian 11 (it used to work on Debian 10).
How to proceed?
$ sudo apt install qt5-default qt5-qmake qttools5-dev qttools5-dev-tools qtdeclarative5-dev qtwebengine5-dev libqt5svg5-dev libqt5websockets5-dev Reading package lists... Done Building dependency tree... Done Reading state information... Done Package qt5-default is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'qt5-default' has no installation candidate
