Yes, just like you said. I have to learn some Fedora commands now because I want to try it out.Not quite probably more accurate to say " Ubuntu/Mint is Debian " so they share last time i looked same command :
but the commands are nothing like that in slackware nor its approach to package management
So its not sudo apt whatever or sudo eopk anymore, but sudo dnf or something.
Hope the graphical interface work most of the time. It's much easier to get information on Debian/Ubuntu commands.
