A Raspberry Pi 3B+ I'm working on, running last week's raspian stretch, kept saying there was something it couldn't do (don't remember just what, but there was a permissions problem).
A little looking around showed a directory called /run/user/1000/gvfs with permissions == d?????????, owner == ?, and group == ?. That would definitely cause a permissions problem. I assumed the SD was corrupt and built a new one -- same thing. I assumed my download was corrupt and got a new one (this week's raspian) -- same thing. I assumed something was corrupting the SD when I installed something, so I built a new SD. Right after NOOBS finished upgrading things, I checked the dir -- same thing. On the Pi (3+, same last week's raspian, and lots of installs) acting as a bridge from WiFi to Ethernet (working), there is no gvfs dir, and the dir below /run/user is 0, not 1000. I looked at the genuine Debian Buster install on the desktop across the room, and /run/user/1000/gvfs was fine: drwx------, owned by me and my group (a bit odd; I would have expected root). There's a man page on gvfs, but I don't understand it. gvfs does things I've never encountered. FWIW, xfce4 is the desktop on everything (except the test right after the NOOBS upgrade). Anybody have any ideas? -- Glenn English
