Thanks for taking the time to report this bug and helping to make Ubuntu better. Could you please add the log files from '/var/log/dist-upgrade/' to this bug report as separate attachments? Thanks in advance.

If you need anything else please tell me cause I'm kind of a rookie trying to find my way around Linux and around Ubuntu. Thanks for all the help on this.
