Hi, I could solve this problems in two steps, first I installed Debian to get more information about the error, so this appears at the end...
systemd-shutdown[1]: Could not detach DM /dev/dm-0: Device or resource busy' systemd-shutdown[1]: Failed to finalize DM devices, ignoring. reboot: Power down With that information, I could find the solution here: https://bugzilla.kernel.org/show_bug.cgi?id=206571 ++++ Go into the BIOS of the laptop, under Virtualization, and DISABLE the option "VT for Direct I/O". ++++ Here are the specs of my Thinkpad X! Carbon 4th gen laptop... $ cat /etc/debian_version 11.3 $ uname -r 5.10.0-14-amd64 $ sudo dmesg | grep ' DMI:' [ 0.000000] DMI: LENOVO 20FBCTO1WW/20FBCTO1WW, BIOS N1FET78W (1.52 ) 12/27/2021 $ lspci 00:00.0 Host bridge: Intel Corporation Xeon E3-1200 v5/E3-1500 v5/6th Gen Core Processor Host Bridge/DRAM Registers (rev 08) 00:02.0 VGA compatible controller: Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07) 00:08.0 System peripheral: Intel Corporation Xeon E3-1200 v5/v6 / E3-1500 v5 / 6th/7th/8th Gen Core Processor Gaussian Mixture Model 00:13.0 Non-VGA unclassified device: Intel Corporation Sunrise Point-LP Integrated Sensor Hub (rev 21) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:17.0 SATA controller: Intel Corporation Sunrise Point-LP SATA Controller [AHCI mode] (rev 21) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #1 (rev f1) 00:1c.2 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #3 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-LP LPC Controller (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection I219-V (rev 21) 02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd.

P.S. Remember to update your BIOS version to the latest version (1.52 at the moment). Have a nice day ;-) ** Bug watch added: Linux Kernel Bug Tracker #206571 https://bugzilla.kernel.org/show_bug.cgi?id=206571 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1972086 Title: Ubuntu LVM + LUKS does not shut down properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1972086/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
