Fix broken packages
Trying to update Linux mint 10 I get first
"Could not download all repository indexes
The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct."
and after that
"can not apply changes Fix broken packages! "
How can I fix this? I'm New in Linux!
