I installed KiCad using the Ubuntu Software application. It installed version 4.0.7 which seems to be outdated.
When I started it I encountered cursor ghosting like in the screenshot below.
This is usually fixed by installing the latest build, following https://kicad-pcb.org/download/ubuntu/
But no matter how hard I try I did not manage to install version 5.16. It always installs 4.0.7.
$ sudo apt list kicad

All packages are up to date.
the source is being updated so why can't I get the software from it?
How can I get a newer software version from a source other than the official Ubuntu repository?
apt-cache policy kicad
