I'm having the same issue on Ubuntu 21.10. It's NOT a VirtualBox virtual machine, but an Ubuntu desktop installation on a physical volume.
When I insert any usb device, it doesn't get mounted, despite org.gnome.desktop.media-handling configuration: $ gsettings get org.gnome.desktop.media-handling automount true $ gsettings get org.gnome.desktop.media-handling automount-open true Here is dmesg log after connecting my smartphone via usb: [13254.311575] usb 3-6: USB disconnect, device number 5 [13265.122249] usb 3-6: new high-speed USB device number 7 using xhci_hcd [13265.250291] usb 3-6: device descriptor read/64, error -32 [13265.506983] usb 3-6: New USB device found, idVendor=2717, idProduct=ff40, bcdDevice= 4.04 [13265.506991] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [13265.506994] usb 3-6: Product: Redmi 9 [13265.506996] usb 3-6: Manufacturer: Xiaomi [13265.506998] usb 3-6: SerialNumber: cXXXXXXXXX [13272.500089] usb 3-6: USB disconnect, device number 7 [13272.946154] usb 3-6: new high-speed USB device number 8 using xhci_hcd [13273.094848] usb 3-6: New USB device found, idVendor=2717, idProduct=ff40, bcdDevice= 4.04 [13273.094862] usb 3-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [13273.094867] usb 3-6: Product: Redmi 9 [13273.094872] usb 3-6: Manufacturer: Xiaomi [13273.094875] usb 3-6: SerialNumber: cXXXXXXXXX -- 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/1946525 Title: Removable media are not mounted automatically Status in udisks2 package in Ubuntu: Confirmed Bug description: 1) Ubuntu Desktop amd 64 20211008.1 daily build 2) udisks 2.9.4-1 3) Inserted disks, in this case the Ubuntu and VirtualBox Guest Additions disk images, should be mounted automatically 4) the automount feature seems to be gone or non-functional in the last couple of days ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: udisks2 2.9.4-1 ProcVersionSignature: Ubuntu 5.13.0-16.16-generic 5.13.13 Uname: Linux 5.13.0-16-generic x86_64 ApportVersion: 2.20.11-0ubuntu70 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME CustomUdevRuleFiles: 70-snap.firefox.rules 70-snap.core.rules 60-vboxadd.rules 70-snap.snap-store.rules Date: Sat Oct 9 01:37:13 2021 InstallationDate: Installed on 2021-10-08 (0 days ago) InstallationMedia: Ubuntu 21.10 "Impish Indri" - Daily amd64 (20211008.1) Lsusb: Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Lsusb-t: /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ohci-pci/12p, 12M |__ Port 1: Dev 2, If 0, Class=Human Interface Device, Driver=usbhid, 12M MachineType: innotek GmbH VirtualBox ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.13.0-16-generic root=UUID=d07fdf87-8838-4ac4-889b-0ae8cdf3ebb5 ro quiet splash SourcePackage: udisks2 UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/01/2006 dmi.bios.vendor: innotek GmbH dmi.bios.version: VirtualBox dmi.board.name: VirtualBox dmi.board.vendor: Oracle Corporation dmi.board.version: 1.2 dmi.chassis.type: 1 dmi.chassis.vendor: Oracle Corporation dmi.modalias: dmi:bvninnotekGmbH:bvrVirtualBox:bd12/01/2006:svninnotekGmbH:pnVirtualBox:pvr1.2:sku:rvnOracleCorporation:rnVirtualBox:rvr1.2:cvnOracleCorporation:ct1:cvr: dmi.product.family: Virtual Machine dmi.product.name: VirtualBox dmi.product.version: 1.2 dmi.sys.vendor: innotek GmbH To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/udisks2/+bug/1946525/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
