Veracrypt device-mapper issue

[Marco-Total]

Hi,

after update my Rasperry Pi OS to Bullseye my veracrypt installation struggle.

root@mapi:/home/pi# cat /etc/issue
Debian GNU/Linux 11 \n \l

root@mapi:/home/pi# uname -r
5.10.63-v8+

root@mapi:/home/pi# veracrypt --version
VeraCrypt 1.25.4

root@mapi:/home/pi# veracrypt --mount --fs-options=umask=000 --non-interactive --protect-hidden=no --password='XXX' /dev/disk/by-partuuid/fefadefd-4e55-402a-9c03-50632421c79e /media/Daten
Error: /dev/mapper/control: open failed: Kein passendes Gerät gefunden
Failure to communicate with kernel device-mapper driver.
Check that device-mapper is available in the kernel.
Incompatible libdevmapper 1.02.175 (2021-01-08) and kernel driver (unknown version).
Command failed.

Cheers, Marco

Which is the most recent kernel version for which Veracrypt works?

[pelwell]

And what do the following commands return?

$ uname -a
$ sudo modprobe configs
$ zgrep BLK_DEV_DM /proc/config.gz

[pelwell]

And:

$ ls /dev/disk/by-partuuid/

Hi,

i can only see, that veracrypt run without this error on 2021-11-05, i run every week a backup script.

Something has gone wrong with your installation - this is what I get running the same kernel build:

pi@raspberrypi:~$ uname -a
Linux raspberrypi 5.10.63-v8+ #1496 SMP PREEMPT Wed Dec 1 15:59:46 GMT 2021 aarch64 GNU/Linux
pi@raspberrypi:~$ sudo modprobe configs
pi@raspberrypi:~$ zgrep BLK_DEV_DM /proc/config.gz
CONFIG_BLK_DEV_DM_BUILTIN=y
CONFIG_BLK_DEV_DM=m

Try running sudo rpi-update 05dc06d to re-install the same kernel and firmware, but first check you haven't run out of disk space.

Do you reboot after updating? If kernel updates that is needed.

[Marco-Total]

Thank you! rpi-update 05dc06d solve my problems!

I think i should update my kernel with apt upgrade? In wich cases i should execute rpi-updade?

root@mapi:/home/pi# uname -r
5.10.63-v8+
root@mapi;/home/pi# sudo modprobe configs
root@mapi:/home/pi# zgrep BLK_DEV_DM /proc/config.gz
CONFIG_BLK_DEV_DM_BUILTIN=y
CONFIG_BLK_DEV_DM=m

Does that mean Veracrypt is working now? If so, the problem was just that the kernel couldn't find a compatible device mapper module.

rpi-update was an attempt to get you back to working system while changing as few things as possible. Under normal circumstances you should only apt update/upgrade/full-upgrade. You could try the following command to put you back on the normal apt install track:

$ sudo apt upgrade --reinstall raspberrypi-kernel raspberrypi-bootloader

Alternatively, you can just wait until the next kernel and bootloader releases, and apt upgrade as normal.
