today i tried to install APM Planner 2.0.26 on Ubuntu 20.04 but it seems that some dependency has removed from Ubuntu repositories or updated to newer version
for example libssl1.0.0 has updated to libssl1.1 to sole this :
- Edit the source list
sudo nano /etc/apt/sources.listto add the following line:
deb http://security.ubuntu.com/ubuntu xenial-security main
sudo apt updateand
sudo apt install libssl1.0.0.
and libqt5serialport5-dev is removed from main repo and you need to manually install it
