Often, the problem is caused by a local cache that is out of sync with the mirrors. Start with these commands to force a fresh metadata download: sudo dnf clean all Use code with caution. Force a metadata refresh: sudo dnf makecache --refresh Use code with caution. Attempt the update again: sudo dnf update Use code with caution.
You can bypass the broken repo to update the rest of your system: sudo dnf update --disablerepo=REPOSITORY_NAME Use code with caution.
