ublue-system-flatpak-manager uses the fedora repo instead of flathub

[ispanos]

Describe the bug

When someone populates the flatpak/system/install list, flatpaks are installed using the fedora remote.

• ublue-system-flatpak-manager removes the fedora remote with --user
• L26 flatpak install --system --noninteractive flathub ${INSTALL_LIST[@]}
• L41 flatpak remote-delete fedora --force

The flathub remote is never installed, thus flatpaks are installed from the fedora remote. Then it gets removed, which disables updates for those packages.

What did you expect to happen?

The expected behavior would either be to fail, since flathub is specified in L26 but it is not installed. This is probably a bug of the flatpak install command.

No response

Extra information or context

I can think of two solutions:

1. Install the flathub repo with --system and remove the fedora repo with --system before installing flatpaks.

Unfortunately this causes all future flatpak installation to require --user, --system or user interaction for all installations in the terminal. If more that one remotes are installed, they need to be specified.

2. Switch to system-wide flatpak installations and install the flathub remote with --user only for non-wheel users, who I believe can't install flatpaks system-wide.

Installing the flathub remote, install the packages, and then remove the flathub remote will not fix the issue of not getting updates.
