[Bug 1964036] Re: Firefox icon missing from panel following Kubuntu upgrade 20.04->22.04

[Brian Murray]

Hello Brent, or anyone else affected,

Accepted ubuntu-release-upgrader into jammy-proposed. The package will
build now and be available at
https://launchpad.net/ubuntu/+source/ubuntu-release-upgrader/1:22.04.15
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-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. 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:
  Firefox icon missing from panel following Kubuntu upgrade 20.04->22.04

Status in firefox package in Ubuntu:
  Confirmed
Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in firefox source package in Jammy:
  New
Status in ubuntu-release-upgrader source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  By removing the firefox deb and installing the snap instead, ubuntu-
  release-upgrader is subverting the logic of the firefox transitional
  deb.

  [Test Case]

  Perform an upgrade from focal to jammy:

  $ do-release-upgrade

  On an affected system, the firefox deb will be removed by the upgrade,
  and the snap will be installed instead. On a fixed system, ubuntu-
  release-upgrader will not remove the firefox deb, and the deb will
  handle the transition to the snap.

  [Where problems could occur]

  If the patch was wrong, e.g. JSON syntax error or similar, it could
  mess up the remaining deb2snap entries.

  [Original Description]

  1) lsb_release -rd

  Description:    Ubuntu Jammy Jellyfish (development branch)
  Release:        22.04
  (Kubuntu Jammy live session in QEMU VM)

  2) apt-cache policy ubuntu-release-upgrader-core
  ubuntu-release-upgrader-core:
    Installed: 1:22.04.6

  3) expected

  (upgrade from Kubuntu 20.04.3 -> 22.04. Reboot.)

  * Firefox icon on panel to be intact.
  * Clicked icon launches browser.
  * Icon tooltip/mouse hover to describe application.

  4) happened instead

  * Icon is missing/replaced with a generic icon
  * Icon click produces error notification "Plasma Workspace - preferred://browser"
  * Icon tooltip/mouse hover appears, though is blank.

  Additional info:
  * firefox is still installed, works as expected.
