Hello! I ran into the same problem - today I installed Open Media Vault 7. I have no Coral driver installed but still after following the steps on their website i received the error:
Error! Bad return status for module build on kernel: 6.12.12+bpo-amd64 (x86_64)
Consult /var/lib/dkms/gasket/1.0/build/make.log for more information.
dpkg: error processing package gasket-dkms (--configure):
installed gasket-dkms package post-installation script subprocess returned error exit status 10
Processing triggers for libc-bin (2.36-9+deb12u10) ...
Errors were encountered while processing:
gasket-dkms
E: Sub-process /usr/bin/dpkg returned an error code (1)
Figured it out: The problem was indeed caused by the Coral Edge TPU drivers, which interrupted the omv-upgrade process and prevented the creation of a proper kernel.
I had to:
- Remove all coral TPU-related references from the apt-sources
- Purge the gasket-dkms and the libedgetpu1-std packges from my system
- Run omv-aptclean
- Run omv-upgrade
After rebooting my system the 6.12.12 kernel worked flawlessly. There was someone with a similar problem caused by an NVIDIA driver, which helped me solve it. In any case, the problem is not related to OMV. Maybe this helps others...
I followed the provided steps, but I'm still hitting the same issue.
