Thanks Roxanne for reporting this bug! I'm moving it to ubuntuone-credentials project, which seems the likely candidate for the fix. We've had other bugs similar to this; maybe there's a better way to fix the account (if it's broken) other than deleting it?

This seems to be a result of the previous signon-apparmor-extension issues that were present in the vivid images once it was added to the seed. Some changes landed in the past couple of weeks which should fix those issues. Can you please verify if this bug is still an issue on the latest vivid image?

Trying to reproduce on vivid:
- created an account on a clean r100
- upgrade to r103
- the account is not deleted during the upgrade process

We also tried upgrading on rtm from 233 to 239 on reports that people had their accounts deleted on that upgrade path. The account which had been recently created also was kept intact.

The current theory at this stage is that u1 accounts older than an ACL account fix are being deleted by u1 code that considers the old accounts invalid.

The store UI will force the user to sign-in again if such an old account is found, re-creating a fixed one in the process. However that upgrade path for old accounts is silent when doing system upgrades. The account is just removed, as technically invalid, but the system doesn't force a new sign in to re-create an account.

Note: the above analysis was conducted by Rodney and Alberto (to give back to caesars... ;)

David's comments are about bug #1413655 and not this bug. I am pretty certain this bug is fixed by the changes which cause that bug.
