Fix - Error: Loading repository 'fedora' has failed

Recently when I tried to update my Fedora laptop I got the below error message

Error: Loading repository 'fedora' has failed

After some debugging I found out that this is due to a corrupted repo cache, we can easily fix this error by clearing all repo caches by running the below command

sudo dnf clean all

If that doesn’t work, you can run dnf command with debug options to see more details about the error.

dnf update --debuglevel 3
