@goemonsama My random tip is about formats you can get software in.
There's a few common formats you'll find offered. Your OS will come with a package manager, basically an App Store, which can download lots of free stuff. A good option, but it may be a slightly old version.
On some websites you'll see them offer .debs and .rpms. These are basically files for those package managers. .Deb will work for you with Debian, Ubuntu, Linux Mint, and many others. .Rpm is for Fedora and it's ilk.
@goemonsama So increasingly software developers making stuff for linux will like to offer downloads that are as unaffected as possible by OS updates. I generally recommend these offerings as you'll be able to usually get the most up-to-date version and it will be unlikely to have issues if you do a major update.
These offerings are usually as FlatPaks, and AppImages. There's a lot of nuances I could get into there, but personally I really recommend grabbing AppImages when you see them.
@goemonsama The free-form nature of Linux means that people will invent multiple solutions to everything which is a burden to those who don't want to weigh a bunch of trade-offs. This is one of cases so yes, my recommendation to you, as a new user, is: the package manager is a great place to get software, if it does not offer what you want or the version there is too old, then I recommend downloading an AppImage from the official creators if they have one.
Ramble over, hope this helps :)
@goemonsama Yo nice! I'm planning to move over myself once I can afford to build a new PC. Not exactly for W11 reasons, though that's a heavy consideration. I just want to challenge myself with a new OS and it's easier than ever to move.
Best of luck in your linux journey!
