Thanks Gordon, I can remember seeing the issue when running Linux Mint back at version 17 - can't remember if it was under MATE (Caja) or Cinnamon (nemo).
Can we as udisk to mount physical media in /media/[volume] and not in the user-specific sub folders? For local users, that would be totally acceptable (and even useful) to be able to share access to USB sticks while plugged in. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to udisks2 in Ubuntu. https://bugs.launchpad.net/bugs/1930312 Title: USB disks and SD cards mount for wrong user Status in Ubuntu MATE: New Status in gvfs package in Ubuntu: Confirmed Status in udisks2 package in Ubuntu: Confirmed Bug description: I have MATE 20.04 LTS installed on a laptop with 4 users. Plugging in SD cards and USB sticks works perfectly, unless there is someone else logged in on the machine. eg: 1- user A logs in, then walks away and screen locks 2- user B switches to the login screen and logs in as user B 3- user B plugs in a USB stick, but it doesn't mount for user B 4- (hidden from sight) user A gets an "authentication is required to mount... /dev/sdb1" error and the window is asking for admin password - details of this are: polkit.subject-pid: 102318 polkit.caller-pid: 806 Action: org.freedesktop.udisks2.filesystem-mount-other-seat Vendor: The Udisks Project user B has no indication on why it didn't mount. If they click on the USB stick in the Caja side bar, they get an "Unable to mount USB Disk - an operation is already pending" So it seems that automount is trying to show the USB stick to the inactive user A, totally blocking user B. (user B doesn't even get the chance to enter an admin password to override) the only solution is basically to "switch account", log in as user A and log them out. (this clearly doesn't work if user B doesn't know their password!)
