** Description changed:
- Using gnome software (or another PackageKit or aptdaemon based UI) to
- install an application - removal of that package leaves behind
- dependencies
+ [Impact]
+ Installing an application them removing it leaves dependencies behind.
- Installing an application with ubuntu software centre only leaves behind
- config files (seen in synaptic labelled for complete removal).
+ [Test Case]
+ 1. Ensure that GNOME Sudoku is not installed:
+ $ sudo apt remove gnome-sudoku libqqwing2v5
+ 2. Check if you have any packages that need autoremoval:
+ $ sudo apt autoremove --no-act
+ 3. Open GNOME Software.
+ 4. Search for and install GNOME Sudoku (make sure to install the .deb, not
the snap).
+ 5. Uninstall GNOME Sudoku.
+ 6. Check if you have any packages that need autoremoval:
+ $ sudo apt autoremove --no-act
- After installing and then removing alarm clock with USC -
+ Expected result:
+ The packages in step 6 are the same as in step 2 (which might be none).
- sudo apt-get autoremove
- [sudo] password for wolf:
- Reading package lists... Done
- Building dependency tree
- Reading state information... Done
- 0 to upgrade, 0 to newly install, 0 to remove and 1 not to upgrade.
+ Observed result:
+ The packages in step 6 includes libqqwing2v5, which is a dependency of
gnome-sudoku and not useful without the game installed.
- After cleaning up and then reinstalling with gnome software, followed by
- the removal
-
- sudo apt-get autoremove
- Reading package lists... Done

- SourcePackage: gnome-software
- UpgradeStatus: No upgrade log present (probably fresh install)
+ [Regression Potential]
+ This requires a fix to PackageKit which used to autoremove all packages (too
aggressive), not just the ones related to the current transaction. A bug in the
code could cause more packages to be removed than is suitable. GNOME Software
previously didn't use this autoremove functionality, so by enabling it we could
trigger a problem in either the existing code or the new fix.
