Where do you mostly download your packages from? Discover and Flathub? Just curious as I switched to Tumbleweed yesterday, and not a big fan of Discover so far... 😅
As someone who also switched from debian-based, the commands are pretty easy to pickup. Instead of apt-get upgrade you have zypper dup, and instead of apt-get install you have zypper install. Have fun with it!
Another very useful command, if you are searching for python packages for example (they get installed via zypper not pip), is zypper se "package name" to search for packages in your repos
Also don't forget the --clean-deps flag when uninstalling a package with zypper to remove unneeded dependencies, for example "sudo zypper rm --clean-depts package_name"
Discover is trash imo, it always crashes when trying to list all the packages to update (maybe that's because of the number of packages i installed? No, impossible! xD)
