No such interface “org.freedesktop.portal.Background” with PikaBackup Flatpak Scheduled Backups

[moshhh]

Hello,

Having an issue with PikaBackup's background process. Using the flatpak. Running linux mint 21.1; with the relevant packages being ubuntu repos, there seems to be no issue on Ubuntu's tracker. Reported on launchpad.

xdg-desktop-portal-gtk - 1.14.0-1build1
flatpak - 1.12.7-1

Output of flatpak run -v when trying to configure scheduled backups

If an application requires o.fd.portal.Background, then it needs xdg-desktop-portal 1.16.0 or later.

There is nothing that Flatpak can do to get a newer xdg-desktop-portal; it's a component that runs outside the Flatpak sandbox, like Flatpak itself, so getting a newer version is between you and your distribution.

So PikaBackup is no longer compatible with Ubuntu 22.10, Fedora 37, Debian 11, CentOS (all) and earlier releases?

If it has a hard requirement on new functionality (I don't know whether it does), then yes. In the absence of a time machine, new features don't exist in distributions that are older than those new features, unless the distribution's policy would allow adding them in later.

Some distributions provide a way to get newer versions of xdg-desktop-portal than the one they originally shipped with; for example, Debian 11 backports include a backport of xdg-desktop-portal 1.16.0.

It was a requirement for automatic backups. Mint was on 1.14 but the latest release should fix this issue.

Never mind this, I was just missing a backend. Pika works fine. Ref. https://wiki.archlinux.org/title/XDG_Desktop_Portal

What do you mean?
As far as I can tell you were right the first time that various OS do not work.
You are now linking an arch linux page where you can update this flatpack component for arch linux.

But if you are using ubuntu LTS or debian LTS, then it does not work.

You need to manually import this specific package from ubuntu lunar (latest version of ubuntu) into LTS instead.
Possibly also other related packages too depending on how they are interlinked.

Well, here I have two systems with Mint 20.3 Cinnamon. On the PC it is working, but not on the notebook.

xdg-desktop-portal-gtk 1.8.0
flatpak 1.12.2
