[Bug 1845690] Re: Do not offer an upgrade from i386 systems

[Łukasz Zemczak]

Hello Brian, or anyone else affected,

Accepted update-manager into bionic-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
manager/1:18.04.11.12 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
bionic to verification-done-bionic. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-bionic. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  Do not offer an upgrade from i386 systems

Status in update-manager package in Ubuntu:
  Fix Released
Status in update-manager source package in Bionic:
  Fix Committed
Status in update-manager source package in Focal:
  Fix Released

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.
