How to Uninstall Software When You’re Not Sure How It Was Installed?

You can definitely use the package manager to check what you have installed. For Flatpak apps, just use the Flatpak interface; it’ll give you all the apps you've installed through it. If you're not sure where the program came from, try listing all possible options—like using `apt list` for deb packages or `snap find` for snap packages. For anything you built locally, check the source directory—you can often uninstall it with `make uninstall`. Good luck!

If you're feeling lost with all the software installed, checking the logs is the way to go. For pacman, the logs are in `/var/log/pacman.log` which keeps track of everything you installed. Just remember, when uninstalling, whether to remove dependencies or leave them depends on if they're needed by other packages. You might want to familiarize yourself with pacman options to avoid scratching your head later.

Haha, I feel you! Linux can be a real puzzle sometimes. The trick is to stick with your distro's package manager for installs and uninstalls. Ideally, tools like snap and flatpak should make this easier, but they really don’t integrate seamlessly with everything. And yeah, it always feels like there should be a simple 'uninstall everything' button, right?

Using the package manager that corresponds to your distribution is important. If you're using a system that comes with a package manager, try to plan your installs around that to avoid future headaches. Also, if you can't remember how you added software, consider keeping a simple record next time.

If pacman is your package manager, I usually prefer the `-Rns` option for uninstalling. It removes the application along with its unneeded dependencies. But if you have no idea how you installed a program, you might need to backtrack and look at your package manager to see what’s there. Checking logs can also help you figure it out.
