Before I migrate from Ubuntu 20.04 to Pop!_OS 21.04 I seek to do the due diligence of backing up everything in my home directory. When I run normally I find FreeFileSync cannot access many, or all, of any directory that begins with a "." because FreeFileSync did not have sufficient permissions. So I ran it as super user using this command:
sudo -i -g me /usr/bin/flatpak run --branch=stable --arch=x86_64 --command=FreeFileSync --file-forwarding org.freefilesync.FreeFileSync @@ %F @@
Now I get in the terminal emulator these errors when FreeFileSync starts up:
(/usr/bin/flatpak run:6396): dconf-CRITICAL **: 10:31:18.234: unable to create file '/home/me/.cache/dconf/user': Permission denied. dconf will not work properly.
(/usr/bin/flatpak run:6396): dconf-CRITICAL **: 10:31:18.234: unable to create file '/home/me/.cache/dconf/user': Permission denied. dconf will not work properly.
F: Can't get document portal mount path
In spite of these errors FreeFileSync does start up. Can these dconf errors be safely ignored? If not, what can be done about them?
