I have zero interest in Chromium. If I really need to use a browser that is not Firefox-based, I can install Ungoogled Chromium. So this is just taking up space in my list of programs both here and in my start menu.

In desktop mode, if I right-click that item in the start menu and choose uninstall, it just opens Discover to the page to download Chromium. There seems to be no way to just remove that "Install Chromium" item.

It seems to be bound to a .desktop file, but I cannot just delete that file because it's in a protected system directory or whatever. And if I were to force it and delete the file anyway, I assume it would just reappear after the next system update.

I cannot install Chromium to get rid of it. Sure, if I follow through and install Chromium, that "Install Chromium" shortcut goes away... but then I have Chromium itself in my list of programs. If I then uninstall Chromium, the "Install Chromium" program comes back.

There must be a simple way to get rid of this that doesn't involve unlocking the system to delete it after every update, right?

Huh, I got rid of it, but cant recall how. Something something via discover iirc. If I find it, I'll update this comment

This got rid of it for me:

cd ~/.local/share/applications
cp /usr/share/applications/org.chromium.Chromium.desktop .
sed -i "$ a Hidden=true" org.chromium.Chromium.desktop

That worked for me!

For anyone wary of running random commands that you don't recognize what they're doing (as you should be wary of), I can vouch that is harmless. It copies a system application file to your local applications folder and then adds the "Hidden" attribute to the file so it won't actually show up. Ran those commands, restarted my headset, and that program doesn't show up in that list any more. Thanks!

I wish I could have made the list and had unwanted menu entries...

Same (ಥ ͜ʖಥ)

Navigating the Linux shell would but much easier if you learned a bit of BASH. Essentially every Linux distro uses BASH for its shell commands, some commands such as cp (copy file/folder), mv (move file/folder), cd (change active directory/folder), rm (remove file/folder), mkdir (make directory/folder) will be on every Linux distro you use, the only time you get new commands is when you install packages that give you new commands, so a command such as fastfetch wont be available to you until you install the fastfetch package.

Hope this helps!

I love how everyone with a frame just switches to librewolf and mpv (including me).

That's very clever, I would've just deleted the file & the updates would've brought it back. (and TIL you can do this)
