Accidentally delete fedora/36/x86_64/silverblue

Hi, I use Fedora Silverblue recently and today someone used my desktop. He accidentally hit sudo ostree remote delete fedora which lead to delete fedora/36/x86_64/silverblue, hence I can’t do rpm-ostree upgrade since it showed error: While pulling fedora/36/x86_64/silverblue: Remote "fedora" not found. Since it has been deleted, do I have the option to add the remote repo back since I can’t find one or should I reinstall the whole with Anaconda? Thank you.

Add the remote again, hints are here:

Hmm I know the command to add a remote but I don’t know the URL for fedora remote. Do you know the URL?

I don’t have a Silverblue install, otherwise it would be easy to look up the URL using ostree show-url.

However, I found this on the web…

ostree remote add --set=gpgkeypath=/etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-36-primary fedora --set=contenturl=mirrorlist=

So I asked in Fedora Discussion and this solution really helped me.
