Could not get list of distribution upgrades

[Ads20000]

Software Updater (gpk-update-viewer) pops up an error with the following information upon running it:

'Could not get list of distribution upgrades
Failed to process request.
More details
The backend exited unexpectedly. This is a serious error as the spawned backend did not complete the pending transaction.'

I expect for it just to work (for it to be able to get a list of distribution upgrades (i.e. none) - for the backend not to exit unexpectedly - for the spawned backend to complete the pending transaction).

The "spawned backend" looks odd... Please execute
 $ pkcon backend-details
and attach the output of it. (if pkcon is not available, install packagekit-tools)

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

Opening Package Updater saying a message All packages are up to date.

Behind that a error message saying

Could not get list of distribution upgrades

Failed to process request
in more details I get:

Spawn of helper '/usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py' failed: failed to spawn /usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py: Failed to execute child process “/usr/share/PackageKit/helpers/aptcc/get-distro-upgrade.py” (No such file or directory)
Tried the following commands but all are doing fine accept openning the package updater.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get --fix-broken install

This has been fixed in packagekit for a while now :-)

@Matthias That's all fine and well, but how do I get the fix to an 18.04 machine with all packages "up to date", yet still unable to upgrade to the next LTS?
