Using the Terminator 2.0 source: On my Ubuntu 20.10 desktop, some files, like the icons, .desktop file, etc. are installed to the wrong location when using python3 setup.py install. Example:

/usr/local/lib/python3.8/dist-packages/terminator-2.0-py3.8.egg/share/applications/terminator.desktop
/usr/local/lib/python3.8/dist-packages/terminator-2.0-py3.8.egg/share/icons/HighContrast/16x16/actions/terminator_active_broadcast_all.png
...etc.

I also tried to install it using --prefix=/usr, but then the application doesn't even start.
