xdg-desktop-portal-gtk conflict after upgrading to Ubuntu 20.04

  • 772

In my Ubuntu 20.04, when I execute sudo apt update && sudo apt upgrade, apt informs me that the package xdg-desktop-portal-gtk cannot be updated. As a consequence, if I try sudo apt reinstall xdg-desktop-portal-gtk I get the message (in italian, but you can easily imagine what it means):

xdg-desktop-portal-gtk : Dipende: libgnome-desktop-3-18 (>= 3.17.92) ma non è installabile

If I run sudo apt list -ua I get:

xdg-desktop-portal-gtk/eoan 1.7.1-flatpak1~eoan amd64 [aggiornabile da: 1.6.0-1build1]
xdg-desktop-portal-gtk/focal,now 1.6.0-1build1 amd64 [installato, aggiornabile a: 1.7.1-flatpak1~eoan]

While the output of apt-cache policy xdg-desktop-portal-gtk is:

  Installato: 1.6.0-1build1
  Candidato:  1.7.1-flatpak1~eoan
  Tabella versione:
     1.7.1-flatpak1~eoan 500
        500 http://ppa.launchpad.net/alexlarsson/flatpak/ubuntu eoan/main amd64 Packages
 *** 1.6.0-1build1 500
        500 http://it.archive.ubuntu.com/ubuntu focal/main amd64 Packages
        100 /var/lib/dpkg/status

Flatpak is installed from its official PPA.

How can I solve the conflict? Is there a chance to "block" one repository for this specific package in order to get it from the other one? If yes, which is the version that I should prefer?

package-management upgrade apt

    Following the idea suggested by Terrance I solved the problem by removing the PPA that caused the conflict. In my specific case, I was able to install the same software from Ubuntu repositories, so I don't need that PPA anymore.
