Trouble installing Flathub

I am using ChromeOS running Debian 12. When I try to install Flathub with sudo apt install Flathub, it returns with E: Malformed line 1 in source list /etc/apt/sources.list.d/lutris.list (type). What do I have to do to fix this?

Seems like there is something wrong with this file

Can you paste the contents of that file? (run the below command)
cat /etc/apt/sources.list.d/lutris.list

I think you might not be able to install any software at all using apt, this is not specifically a flathub issue

Flathub is a repository for Flatpak, which is a packaging technology. So, the correct steps to activating Flathub are to install Flatpak, and then to add Flathub as a Flatpak repository.

You can find the commands to activate Flathub here:

uhh i just realized i messed around with it accidentally so the contents is

how can I fix this?

That’s certainly something…

If I’m right, you tried to install Lutris, correct?

You should be able to safely remove this file, and then apt should work again:

sudo rm /etc/apt/sources.list.d/lutris.list
sudo apt update

tysm! Flathub is finally installing now
