Comment 5 for bug 1746039

As a rule of thumb, Long Term Support releases are not normally times for making significant changes to the seed. Based upon a quick look at the task sets in aptitude we see that Ubuntu, Ubuntu Kylin, and Ubuntu MATE carry deja-dup in their seeds while none of the other flavors do. To consider adding this to the Xubuntu seed we need to consider it against the Xubuntu Strategy Document's criteria. See: https://docs.xubuntu.org/contributors/xsd.html

I'll specifically turn to seed composition as seen here: https://docs.xubuntu.org/contributors/xsd.html#xsd-seeds-composition

* The package should use the GTK toolkit

GTK 3

* The package should not pull in heavy libraries, especially if they will run and/or start frequently

There are no reverse dependencies found. This will drag in "duplicity" compared to what we pretty much already have installed in a base install. Installation of deja-dup adds roughly 5 megabytes of installed software to my current 20.04 work-a-day testing installation.

* The package should be well maintained upstream

It appears so.

The current version installs and shows up in the menu under the GNOME-ish generic title of "Backups". There are UI quirks that seem nonsensical such as an on-off toggle in the menu bar that does not seem to do anything. In terms of look and feel it does not integrate well with the rest of the system.

Since this wasn't tried in any interim release prior to the focal cycle I would weigh in against making the change now and delaying for the G cycle unless something other than deja-dup is considered.
