I use GNU/Linux Mint 18.2 (based on Ubuntu 16.04). Very recently, I've started seeing the following error message, repeated many times, when I start some GUI apps (e.g. meld):
unable to create file '/run/user/1000/dconf/user': Permission denied. dconf will not work properly.
Now, I'm able to work around this by manually changing the ownership of
/run/user/1000/dconf/user, but that's kind of a lame hack and certainly not robust.
Why have I been seeing this error and what's the "right way" to avoid it (if any)?
