Hello guys, I’m just recently using Fedora Silverblue 36. Someone used my desktop and accidentally hit ostree remote remove fedorawhich eventually remove fedora/36/x86_64/silverblue in my desktop. I have been trying to llok for the url to reinstall but I don’t find one. Any suggestions? Can I install the repo back or should I reinstall the whole OS from live USB since I can’t do rpm-ostree upgrade at all? Thank you 
Hello @handsomeguy ,
try sudo ostree remote add fedora https://ostree.fedoraproject.org. Should get the fedora remote back
Hmm but I still can’t either upgrade or update rpm-ostree yet since the terminal said
error: While pulling fedora/36/x86_64/silverblue: Server returned HTTP 404though the list of fedora remotes is available.
Perhaps the url is not complete without the trailing /.
I remembered that I’d given it a try and it didn’t work. Additionally, the terminal kept crashing and I decided to reinstall Fedora. So far, I do not face serious problems anymore. Thank you @jakfrost for your help.
