Would it be possible for you to manually run the upgrade on the same system?

[Victor Zhou (victor.zhou)]

@Joseph
yes, I will try to run this manually

[Victor Zhou (victor.zhou)]

there is a similar issue in the upgrade from precise to quantal desktop, and it disapear after I re-test it. let's wait for the next run of this case, and I will report the result and keep dig the root cause.

[Victor Zhou (victor.zhou)]

This test passed in today's run. and I will keep an eye on this issue in the coming days, to check if this will occur again and dig the root cause.

[Steve Langasek (vorlon)]

This issue no longer shows up in the latest run of that jenkins test. Closing this report as invalid.
