Update failed for unipi-kernel-modules-dkms 1.60

When updating via apt the build process fails on Neuron M103:

I did a reboot, did a "apt purge unipi-kernel-modules-dkms", "apt install unipi-kernel-modules-dkms" with exactly the same output.

Hello @Joerg,
this was caused by RPI releasing a new kernel (5.10). Since we release the appropriate kernel modules manually after testing, the APT decided to install the module via DKMS, which was also not prepared for the new kernel.

The unipi-kernel-modules 1.62 fix this. apt update && apt upgrade should fix it.

Best regards,
Martin

nipi-kernel-modules

Hi @Martin-Kudláček ,

thank you for the quick answer - but after the "apt purge unipi-kernel-modules-dkms" the system did not want to boot anymore, so I decided to do a fresh install as described in README.apt.

Best regards
Jörg
