gnome software leaves dependencies installed

Does USC do an autoremove afterwards or does it explicitly remove dependencies?

to be honest - I have no idea what USC actually does.

Given that the dependencies aren't there to autoremove I would assume that it does do that.

Michael Vogt confirmed that USC automatically removed unused dependencies. We should do the same.

See aptdaemon/worker/aptworker.py:711 _check_obsoleted_dependencies()

Any progress regarding this issue?

Still the same issue in 17.10

Any news?

This issue is there since Ubuntu 16.04. There is not any user-friendly (for regular users) way to remove the dependencies. It is a problem since many applications depend on other applications, parts of other desktop environments etc. and removing the applications leave users with many unwanted applications/packages they are not able to remove. Please, fix this issue.

For example uninstalling Steam is a problem because of this issue: https://bugs.launchpad.net/hundredpapercuts/+bug/1564570/comments/18

I really hope that this bug will be finally fixed in Ubuntu 18.04.

Slightly related issue: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1528028

I have created a separate bug report for the Steam issue: https://bugs.launchpad.net/ubuntu/+source/steam/+bug/1741047

https://github.com/hughsie/PackageKit/issues/201#issuecomment-347640675

The aptcc PackageKit backend developer told me that autoremove is already supported for more than 5 years, since this commit from 2012: https://github.com/hughsie/PackageKit/commit/94a5e71ded685720e49f17dc6ee21716b33ac177

But it still does not work when using pkcon or GNOME Software. Maybe it is not enabled by default?

More information from Julian Klode (https://github.com/hughsie/PackageKit/issues/201#issuecomment-364363222):

"Sure, it's an option given to backends, see pk_backend_remove_packages() - it's a parameter in the Dbus API's RemovePackages() method. In the client API, you can specify it as a boolean parameter for pk_client_remove_packages_async.

But it's not the kind of autoremove that would be correct for gnome-software - gnome-software needs to remove "new garbage", that is only packages that become unused as a result of the removal and not any other unrelated garbage that has accumulated over time."

It would be great if the correct autoremove method could be implemented in PackageKit or GNOME Software.

As I wrote in the github PackageKit bug report: I offer 1 ETH (currently ~852 USD) to anyone who manages to implement (and gets upstreamed) a working autoremove support for packages that are uninstalled using GNOME Software on Ubuntu/Debian. ;-)

I don't have the ETH anymore, but I will send $600 via PayPal to the one who fixes this issue.

Still no progress regarging this issue?

Upstream bug report: https://github.com/hughsie/PackageKit/issues/245

VLC is another package where uninstallation is problematic: https://bugs.launchpad.net/ubuntu/+source/gnome-software/+bug/1746728

Status changed to 'Confirmed' because the bug affects multiple users.

It looks like the PackageKit change will be accepted upstream - this stops the autoremove functionality to only remove dependencies of packages being removed. This matches the old aptd behaviour.

GNOME Software will have to be distro patched however, as upstream considers this functionality not reliable - since we have limited backends on Ubuntu we can enable it however.

Cant Gnome software add a define as a build option like I do in Apper?
