Isn't there a lot of overlap though, at least between OSes that are of the same type (like debian/ubuntu)? How to set up users, knowing that you need to manually configure automatic mounting of your drives, knowing how/when to use flatpak or apt or .deb, where to install apps... These are not really intuitive things, especially for someone coming from windows, and most "how to install linux" guides don't really go into these in any meaningful way.
For instance at first I thought I could just keep a list of apt commands and make an "easy to reinstall" linux script at one time, and that lasted for whole of 10 minutes before I realized every app needs manual intervention in one or another way, or has a different way of installing. Also, as many people I just prefix everything with sudo to get it to install, but who knows if that is the correct thing to do? not me at least
I'm trying out popOS and even the native package manager (popOS shop?) installs most applications as flatpaks afaik? I have no idea where they end up being compared to windows' program files or what kind of defaults they install with. I started putting my custom downloaded AppImages into the ~/Applications folder and then used AppImageLauncher to actually have them show up in search.
Then I will run into something like docker which is not in the shop and has a ton of commands you have to run in order to get it to work, like uninstalling conflicting packages, installing some certificates and keyrings and i dont even know what - it was supposed to work better than on windows but it is nowhere near as neat as there!
Then I install samba (again, not available in the popOS shop) and I have it running but i have no idea whether it's set to automatically run or not. Searching for it with GUI tools doesn't show it as installed anywhere so in this case i have to rely on the terminal. The popOS store does have a list of installed apps but the search field gets disabled when you go into this screen because it's only used for browsing the shop, not through your installed apps?
This is what I do but the issue is that I have no feedback on whether Im doing the right thing or if im making the life unnecessarily difficult for me. Games will slap you and make you redo something if you fuck it up, linux just makes you live in agony until sometimes breaks and you dont know why.
