[Bug 225361] Re: .gvfs can't be stat'd by root causing backup tools to fail
Here is a possible solution. My system - Mint 19.1 x64 Cinnamon - had no .gvfs directory in /run - but it did have one in /home, causing the rclone backup tool to report errors. I discovered (from here: https://forums.opensuse.org/showthread.php/387162-permission-denied-on- gvfs) that I could remove the .gvfs folder thusly: sudo umount /home//.gvfs sudo rm -rf /home//.gvfs (That webpage lists a different method for removing the directory. That other method involves iodes; and that other method did not work on my system, but the one I gave above did.) So far, gvfs seems to work without the .gvfs directory in /home. (That seems strange, considering there is no such directory in /run either.) Nor has the .gvfs folder been regenerated - at least not yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/225361 Title: .gvfs can't be stat'd by root causing backup tools to fail To manage notifications about this bug go to: https://bugs.launchpad.net/gvfs/+bug/225361/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 225361] Re: .gvfs can't be stat'd by root causing backup tools to fail
The bug is that doing a stat on .gvfs as root causes an error, which upsets rsync et al. When .gvfs was in your home dir, that means you would have problems backing up your homedir: rsync would fail when it got the stat error. That bug is not fixed, but .gvfs has now been moved to /run, which is a separate filesystem, backed by tmpfs (i.e. virtual memory) which you would not normally be backing up.
