Thanks for compiling. Synaptic (on Linux Mint 20) aborts installing
LyX from the PPA with the messages: 
Vereisten: libqtcore4 (>=4:4.8.0) but it is not installable
Vereisten: libqtgui4 (>=4:4.8.0) but it is not installable
Vereisten: libqt4-svg  but it is not installable

It seems Qt4 is no longer supplied on Focal.

Best,
Kees
