Unable to install Flatpak's

I’m new to Linux and I’ve been trying to install the Flatseal Flatpak but I’ve been unable to so far. Here were the steps I took and the issues that came along with them.

1) Search “Flatseal” in Software - No Application Found

2) Install Flatseal using terminal - error: Nothing matches com.github.tchx84.Flatseal in remote flathub

3) Install flatpak using flatpakref file- No entry for app/com.github.tchx84.Flatseal/x86_64/stable in remote ‘flathub’ summary flatpak cache

This also happens for other Flatpaks such as Discord, but some (such as Bitwarden) still work.

You probably don’t have the full flathub repo but the Fedora curated version.

Try removing the flathub repo and adding it back with:

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

Alternatively, you could use the link on this page.
