Comment 8 for bug 979477

Johnny, the issue you're seeing is not this bug; this bug is only about apt proxy settings being applied in cases where admins are not prepared to have them applied.

This is because gksudo is not included in Kubuntu. A known issue with the previous upload; I've filed this as bug #982032.

Your real issue is that the download failed at all at package install time.

I have not seen this error here. It's a very strange error, as it suggests that python's urllib was unable to parse the url that was passed to it - the same url that's shown immediately above the failure in the output.

Please file a separate bug report against the update-notifier package by running the command 'ubuntu-bug update-notifier' from the affected system, so we can capture information about anything that may be wrong with your python installation.
