[Bug 1799710] [NEW] 18.04->18.10: update-manager don't show upgrade page

[DnsF]

Public bug reported:

Hello,

I want to upgrade to 18.10.
So I start update-manager GUI then update some packets.
At End it ask me if I want to upgrade. I answer Yes.
But update-manager close. Nothing happens.

I run it under terminal and get this message:
Please install all available updates for your release before upgrading.

Why GUI don't show this before close?
