Any idea about cannot access repo after upgraded from Fedora35 to 37?

Ask Fedora

The error looks like below, I guess the main reason is “Opening repository primary data has failed: No such file or directory.” Any idea about this error?

dnf -v update

Try to refresh your dnf cache with:

dnf -v update --refresh

Thanks, tried and still failed. Below discussion solved my problem.
The history is very long, the answer is short for my problem.

Append “zchunk=false” to "/etc/dnf/dnf.conf ".

Here is my settings now:
[main]
gpgcheck=True
installonly_limit=3
clean_requirements_on_remove=True
best=False
skip_if_unavailable=True
zchunk=false

Just a note beside your solution, to tune up your download speed (if your internet is fast enough!):

max_parallel_downloads=10

adding to your /etc/dnf/dnf.conf

Did you try cleaning the DNF cache before disabling that option?

sudo dnf clean all

Yes, did clean all and it did not work.

Thanks, got another tip from the thread, cheers!
