I will try another distribution and read about Zorin. Before installing on a productive Computer i had try the Core version, but read about the program Fritzing included in the Education Edition.
Normally it could be easy to take a core edition an install Fritzing. But this is not working. After installing the core.fzb cannot be found by the program (no such file or directory). This is a little bit strange because i think the installing process is given by flatpak (or snap?).
I tried another package “moneydance”. After starting there is a terminal called “snap”, but nothing happened.
I think it is important to correct these things. Zorin has a lot of eye-candy, but more important is a executable distribution. And what i wrote about is really a problem for people who want to switch to a new distribution.
