Ubuntu 20.04 LTS problems in 3.0.0

[rogermartensson]

(I did notice that you have started Ubuntu 20.04 support in master but not yet released.)

I get these warnings on a Ubuntu 20.04 LTS but I think some of it might be needed to be changed for as old as 16.04.
I looks like some defaults may need to be updated and some changes made in the template?

I'm sure I can create a local workaround by using my own settings but it would be nice if it wouldn't be needed.
