Error: Unable to download packages from repository. System is not modified.


This could come up because the existing yum cache isn't cleaned it. To fix this, first run:

yum clean all

Clear Yum’s XML metadata by running the following command:

yum clean metadata

Run following command to clear the cached files for database.

yum clean dbcache

Then update the yum metadata again:

yum makecache
