Still affects Ubuntu 24.04 LTS on kernel 6.17 (May 2026)

Confirming this is still broken with the latest HWE kernel series.

Environment:

Ubuntu 24.04 LTS (Noble)
Affected kernels: 6.17.0-19-generic, 6.17.0-23-generic
Working kernel (fallback): 6.14.0-37-generic
Package version: openvpn-dco-dkms 0.2.20250801-2+noble
Symptom:
DKMS build fails during kernel post-install (dkms autoinstall ... failed for 
ovpn-dco(10), exit code 11). Because the kernel postinst aborts on this 
failure, update-initramfs never runs, leaving the new kernels with no 
initrd.img. On the next reboot, GRUB defaults to the new kernel and the system 
kernel-panics with:


VFS: Unable to mount root fs on unknown-block(0,0)
The only way to recover is booting an older kernel from GRUB's recovery menu.

Workaround:


sudo apt purge openvpn-dco-dkms
sudo dpkg --configure -a
sudo update-initramfs -c -k <affected-kernel-version>
sudo update-grub
This is a fairly severe failure mode for end users — a routine apt upgrade 
silently leaves the system unbootable until the next reboot. Would be great to 
see the package either updated for kernel 6.17 compatibility, or for the DKMS 
build failure to not block initramfs generation.
