I noticed that the update option wasn’t appearing in the software center so I ran
ostree remote refs fedora | grep silverblue | grep $(uname -i)
In the terminal and the output was
error: While fetching https://ostree.fedoraproject.org/summary.sig:  Timeout was reached
did you tried just the command
in my case I got nothing just unkown, that’s weird and it should be a bug
ostree remote refs fedora | grep silverblue and choose manually
or use this one
ostree remote refs fedora | grep silverblue | grep x86_64 if that’s your platform
about your error is just a network timeout, just try again
Im doing what the docs told me to and I’ve been trying over and over it won’t work I did just run
ostree remote refs fedora | grep silverblue | grep x86_64 and I got the same error.
then just rebase using
rpm-ostree rebase fedora:fedora/38/x86_64/silverblue
you have an issue with the server that feeds the data ostree uses, but you just need the line I just gave you to rebase.
