mintbackup

[deck-luck]

Problem:

The mintbackup program does not produce or save a list of Software Manager installed packages.

Steps to reproduce the anomaly:

Start mintbackup In the Software selection section select the "BackUp Now" button. The next window indicates the following: The list below shows the applications you installed with Software Manager

The list is empty; even though, I have previously used the Software Manager to install the ncdu package. After hitting Forward button it pretends to successfully complete. See the mintbackup terminal session output for additional error messages.

Terminal session output:

Looks like a regression from mint-common/mintinstall changes.

[carlosmintfan]

Because you ported AptDaemon to PackageKit?

[carlosmintfan]

Ah, did you port mintbackup to Packagekit too? Do you prefer it?

[carlosmintfan]

@mtwebster Do you prefer packagekit over aptdaemon?

[mtwebster]

Mintbackup has been using our installer in mint-common - we ported that to use packagekit instead.

I prefer packagekit for a few reasons:

• aptdaemon seemed a bit brain-dead at times trying to resolve dependencies - not sure why they'd be different while using apt underneath, but apt has multiple ways to do a lot of things so I imagine there is some potential for different behavior.
• packagekit uses GLib/GObject which we're familiar with, and its API is fairly similar to Flatpak's, which is great when dealing with both types of packages in the software and update managers. Aptdaemon's was weird and clunky to me.
