Bug Description

Impact
------
Ubuntu 18.04 users on a system with a host architecture of i386 will be offered to upgrade to Ubuntu 20.04 only to later be told by ubuntu-release-upgrader that they can not upgrade to 20.04. Rather than have people experience this we'd like to SRU update-manager to notify users of the fact that they will not be able to upgrade to 20.04.

Test Case
---------
1) On an 18.04 i386 system set Prompt=lts in /etc/update-manager/release-upgrades
2) run update-manager -d
3) observe a notification about a new release of ubuntu and see the release announcement
4) start the upgrade and observe a dialog telling you that you system can't upgrade
5) wonder why you wasted so much time trying to upgrade

With the version of update-manager in -proposed you will instead be immediately presented with a dialog that says "Sorry, there are no more upgrades for this system".

Regression Potential
--------------------
While not strictly speaking a regression this dialog is not translated but we think it is better that be notified that there are no upgrades rather than being lead to believe that they can upgrade only to be told no.

Original Description
--------------------
Given that there will not be a full set of i386 packages for Ubuntu 19.10 and that it will not be possible to upgrade to Ubuntu 19.10 it'd be best if the new release dialog were not displayed for systems with an apt architecture of i386. The message should indicate how long they will continue to receive updates for and present information about reinstalling using amd64 (if that's possible). These changes will need to SRU'ed to both Ubuntu 18.04 and Ubuntu 19.04.

One way to present this information would be to create a new class of Dialog in UpdateManager/Dialogs.py which is raised, from UpdateManager/UpdateManager.py, if the apt architecture is i386.

While the additional dialog will not show up in update-manager on systems running 20.04 (because we have no install media for i386 and ubuntu-release-upgrader already prevents i386 users from upgrading) I have emailed the ubuntu-translators list regarding the additional strings be added.

I just booted a Lubuntu 18.04.5 (i386) QA-test install for support & testing purposes.

(QA) Install was performed 2020-Sept-08, but on login the first pop-up was an offer to upgrade the system to 20.04. This system hasn't been touched since the QA install back in 8-Sept.

I've seen many reports (support, askubu etc) claiming the same.
