** Description changed: + [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. + 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.
