Updating repository information
WARNING: Failed to read mirror file

No valid mirror found

While scanning your repository information no mirror entry for the
upgrade was found. This can happen if you run a internal mirror or if
the mirror information is out of date.

Do you want to rewrite your 'sources.list' file anyway? If you choose
'Yes' here it will update all 'lucid' to 'precise' entries.
If you select 'No' the upgrade will cancel.
