Unable to refresh repos

I get the following errors when I try to refresh my repos (also this keeps popping up on my Update Applet)

Cannot access installation media
Index of /update/11.2

Failed to download ./repodata/886603b5c7e8f047b48851b7cb7668c5676ddcf0-deltainfo.xml.gz from Index of /update/11.2

Any suggestions?

I’m getting the same error.

I tried to refresh manually and received an error about the key.
It’s a skull scratcher.

This might help with the key issue ?
