Snaps only run after a long timeout



my snap applications only start after a long delay. The error message is:

2018/12/28 17:23:36.861954 cmd_run.go:844: WARNING: cannot start document portal: Failed to activate service ‘org.freedesktop.portal.Documents’: timed out (service_start_timeout=120000ms)

It affects all snap applications I have on my system (gimp, libreoffice, inkscape)

It only started recently. Is this a known issue?


  1. Can you please show us the output of snap version?
  2. Is the problem limited to GUI applications or do command-line applications also exhibit the delay?
  3. Have you tried rebooting or at least running systemctl restart snapd and trying again?


Hello Daniel.

No problem. Outputs bellow. Problem seems limited to GUI applications (thanks for the tip, I never had non-GUI snaps before).

I have apt remove snapd apt install snapd and reboot. I have now tried systemctl restart snapd and no change occurred. I have also tried other things. The org.freedesktop.portal.Documents causing the timeout seems to come from flatpak, so I uninstalled flatpak and reinstalled it from the alexlarsson ppa. No change. Tried installing the apps I had as snaps as flatpaks (GIMP, Inkscape and Libreoffice bc of the versions in the official repos) and there was a delay (like 10 seconds), but that is also not acceptable. For now, I searched for ppas with latest software versions and installed them via apt, but I would like to be able to use snaps. This must have come with one of the recent bionic updates.
