Baidu did not search for the relevant problem, and finally found a temporary solution outside the wall.
It’s probably a bug of Zchunk, just disable Zchunk in the dnf configuration file.
>$ sudo vim /etc/dnf/ dnf.conf # Add the following at the end of the file zchunk = False # :wq save and exit # Restart packagekit service >$ sudo systemctl restart packagekit.service # Re-update the cache >$ sudo pkcon refresh force
