Some updates, while I'm still investigating this on a QEMU running Ubuntu Core 22.
The "snap auto-import" command is only needed on Ubuntu Core systems, so the plan is to remove the /lib/udev/rules.d/66-snapd-autoimport.rules from the snapd deb package (and consequently also from the snapd snap). We do still need it in UC, but as a matter of fact the script is already provided by the Ubuntu Core repositories: - UC22: https://github.com/snapcore/core-base/blob/main/static/usr/lib/udev/rules.d/66-snapd-autoimport.rules - UC20: https://github.com/snapcore/core20/blob/master/static/usr/lib/udev/rules.d/66-snapd-autoimport.rules - UC18: https://github.com/snapcore/core18/blob/master/static/lib/udev/rules.d/66-snapd-autoimport.rules - UC16: **missing** The file in UC22 seems already correct, in that it does not call unshare. So the only one left out is UC16, where we will add the udev rule that we currently have in snapd; after that, we will remove the rule from snapd and this bug for the desktop will be gone for good. There is a remaining problem, however: the systemd-udevd.service in Ubuntu 22 disallows the mount operation, so we'll have to update the unit file to allow it. I think we'll also need to update the auto-import command itself, because it appears that all errors while accessing the devices are silenced, so we would have never known of this problem, if it wasn't for this bug report. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1966203 Title: Syslog shows "systemd-udevd[2837]: nvme0n1: Process ... failed with exit code 1." in Ubuntu 22.04 Status in snapd: Confirmed Status in systemd package in Ubuntu: Invalid Bug description: Configuration: OS:jammy-live-server20220320-amd64.iso CPU:AMD EPYC 7702 64-Core Processor UEFI Version:D8E119A BMC Version:D8BT19I SSD:Intel 1.60TB NVMe SSD Boot mode:legacy Reproduce Steps: 1.Boot into BIOS and set boot mode to legacy 2.install ubuntu 22.04 on NVMe SSD 3.Check syslog log Current behaviors: syslog shows systemd-udevd errors in Ubuntu 22.04 Feb 9 10:16:19 len systemd-udevd[2837]: nvme0n1: Process '/usr/bin/unshare -m /usr/bin/snap auto-import --mount=/dev/nvme0n1' failed with exit code 1.
