It's a strange one. I appear to have had this as well. The output from dmesg shows it detects the drive just fine. It also appears in Nautilus, which will mount it for you when you click on it, but that's obviously a complete no-go.
What fixed it for me was simply reinstalling the fuse package: sudo apt install --reinstall fuse and rebooting, as per the advice here https://askubuntu.com/questions/1361627/ubuntu-mate-21-04-usb-stick- will-not-automount which I know isn't 21.10, but worked for me regardless. No clue why it went wrong in the first place, but at least I've got it sorted for now. -- 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 : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
