Comment 3 for bug 528203

I am marking this as the master bug report of this kind of problem.

The reason why this happens is: ubuntuone-client-gnome contains ubuntuone-login in r321. Ubuntuone-client-gnome depends on ubuntuone-client r321. In order to upgrade the system completely, apt starts upgrading ubuntuone-client first, leading to the problem described. r394 of ubuntuone-client has ubuntuone-login script, while r394 of ubuntuone-client-gnome does not have one.

The solution is to remove ubuntuone-client and ubuntuone-client-gnome packages then install them again. The dependencies will then be resolved in correct order.
