Apt is an Ubuntu tool. You can use the built in "add/remove software" tool (pamac) or command line equivalent to apt for Garuda is pacman. When you are googling for help, search for Arch Linux related help as Garuda is based on Arch linux which has different tools than what you are used to. The archwiki is going to be your friend.
No problem. Also, if you are going to have your shell startup modified, with the default fish shell you'll need to modify this file: ~/.config/fish/config.fish
If you search for where "paleofetch" is called towards the bottom of the file you'll see where the current default popup is being called and you can either comment that out and enter your own figlet command or whatever.
As a general rule the most insecure thing in your installation of most linux distros, is you. Stop being insecure (that's the best I can do, because I have no app to stop you from doing insecure things).
OK, thanks that is great advice, however I tried installing snapd but with errors, so I have already fell victim to the most insecure part of my system.
Since read up that snapd is spyware I would like to remove any damage it has done if any, or just remove what was installed.
It does not show up in installed apps?
yet did say it was installed, I found the errors when I tested the install by running the hello-world thingy, it didnt process correctly.
