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.

Some users are reporting that changing the repository to "Main Server" allows them to complete the upgrade.

Could you please remove the package libcupsys2 and tell if it helps ?

[Martin Truffer (truffer)]

That did it. I successfully upgraded now. Thanks
