[Bug 1947501] Re: update-manager should not remove deb-packaged Firefox on flavors

[Chris Halse Rogers]

Hello Norbert, or anyone else affected,

Accepted update-manager into impish-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
manager/1:21.10.5 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-
impish to verification-done-impish. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-impish. 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.

  update-manager should not remove deb-packaged Firefox on flavors

Bug description:
  [Impact]
  update-manager lists Firefox as a duplicate package to be removed for Ubuntu flavors which installed it by default.

  [Test Case]
  1. Install Ubuntu MATE 21.10 online or off-line (does not really matter)
  2. Login to freshly installed system
  3. Run `update-manager` manually

  Expected results:
  * update-manager founds some useful updates and install them

  Actual results:
  * update-manager founds some useful updates and will remove Firefox web-browser to replace it with Snap version
  See screenshot and its OCR main part:

    Details of updates
      Install or remove
          Duplicate packages to be removed
              Firefox Web Browser

  With the version of update-manager from -proposed Firefox will no
  longer be suggested for removal on a system without the ubuntu-desktop
  package installed.

  [Where Problems Could Occur]
  It's possible the Firefox deb will no longer be suggested for removal on systems with ubuntu-desktop installed. To test this scenario we can also install the ubuntu-desktop package on the Ubuntu MATE system from the original test and confirm that firefox is suggested for removal.

  [Original Description]
  Additional info:
  * in /usr/share/ubuntu-release-upgrader/deb2snap.json you clearly state the dependency on ubuntu-desktop package (https://git.launchpad.net/ubuntu-release-upgrader/tree/DistUpgrade/deb2snap.json#n10 ), but flavours does not have such package installed, so it is a bug.

  Workaround:
  * mark Firefox as manually installed by `sudo apt-mark manual firefox` and then launch `update-manager` again.
