SOLUTION: add Flathub as a user remote too:
flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak lets you install applications as user vs system. I want to install as user because my .var is full.
example: flatpak install --user org.fcitx.Fcitx5 returns error: No remote refs found for ‘org.fcitx.Fcitx5’
flatpak remotes returns flathub system
I’m logged in as user5. whoami returns user5
I don’t know what remote I have to add or if I have to add user5 as a remote
What’s happening here is that you only have a system-wide remote configured, but you’re trying to install as user. Flatpak keeps two separate sets of remotes:
System remotes (available to all users)
User remotes (only for the logged-in user)
Since you have no user remotes defined, Flatpak can’t find anything when you do --user.
You need to add Flathub as a user remote. Run:
flatpak remote-add --if-not-exists --user flathub https://flathub.org/repo/flathub.flatpakrepothanks. I read that command somewhere but thought I had to edit it to name specifically my username.
