I can not upgrade after closing the update halfway for checksum mismatch

[nalinidash]

Hello everyone.

I tried yesterday to upgrade to fedora 34 beta using dnf-plugin-system-upgrade.It went fine yesterday but due to the time required I closed the upgrade halfway and went to sleep.Today when I tried to continue to update I got the error like

Errors during downloading metadata for repository ‘updates’:

• Downloading successful, but checksum doesn’t match.

  Error: Failed to download metadata for repo ‘updates’: Cannot download repomd.xml: Cannot download repodata/repomd.xml: All mirrors were tried

How to solve this error?Thank you in advance.

We are very close to get F34 rolled out. There is a lot to sinc between the mirrors. Be patient and try again.
Maybe this helps:
dnf --refresh #set metadata as expired before running the command

I will wait for that.I just wanted to know what caused that error.
Thank you!
