Cmd_run.go:893: WARNING: cannot start document portal: Can't mount fuse fs

I haven’t touched my system for a week and now see this error.
What can be done besides reboot and how to prevent it?
I know that 2.40 is out but it is not on epel channel yet.
$ snap --version
snap 2.39.2-1.el7
snapd 2.39.2-1.el7

From the look of it, the “Can’t mount fuse fs” part of the error message comes from the xdg-document-portal service. Here are a few things that could help narrow down the problem:

  1. what is the version of the xdg-desktop-portal package installed on your system?

  2. does systemctl --user status xdg-document-portal.service show any interesting log messages?

# rpm -q xdg-desktop-portal
# systemctl --user status xdg-document-portal.service
Failed to get D-Bus connection: Connection refused
# exit
$ systemctl --user status xdg-document-portal.service
Failed to get D-Bus connection: No such file or directory

$ systemctl --user status xdg-document-portal.service
Failed to get properties: Process org.freedesktop.systemd1 exited with status 1

however, it seems that this warning is indeed a warning, application started after a system reboot and warning is still present.

I don’t have access to a RHEL7 box, so it is a bit hard to help debug this.

You shouldn’t use sudo when calling systemctl --user, since we are trying to talk to the user instance of systemd (which root has no access to). I’ve got no idea why you’re getting the “Failed to get D-Bus connection: No such file or directory” error when calling it as the regular user though.

Is there anything unusual about the way you’ve started your desktop session on the system?

hi, could you try this snap? can it read a picture? or any data? I’m on this error If I install this snap, picture:
