Flatpak returned "Remote "zorinos" not found" after reinstalling flatpak

[pizzzzza]

Flatpak ran into some problems and I tried to reinstall it, after this there's only one repository called "system" but no "zorinos". I tried "flatpak update" and this returned.

 ~  flatpak update                                                                                             ok  09:25:09

How can I get the repo "zorinos" back?

Thanks very much, it's pointing to main but it still returned the same error. After I reinstalled flatpak, there's no remote and I added the "flathub" one, but I don't know the url of "zorinos" remote so I can't add it back.

There were some problems with the remote gpg and use apt remove can't solve it , so I tried sudo apt purge flatpak and lost the remotes.

I tried to boot a CD in a virtual machine and run flatpak remotes --show-details. I found the url is https://flatpak.zorinos.com/repo/

So I tried flatpak remote-add --no-gpg-verify zorinos https://flatpak.zorinos.com/repo/

Then I checked update and it worked properly

Solved, thanks very much.
