i have tried autoclean and auto remove dont work sadly.

anyone have any idea on how to solve this issue?

 

[fabian]

mount the ESP manually, remove unwanted kernels, unmount again, then repeat the APT invocation.

Is it possible to have more detailed instuction how to solve the issue?
I have zfs boot drives in zraid configuration from installation under version 6. I have already upgrade to ver.7 year ago. Everything was ok until something happened this summer.
I have no "sda1, sda2".
Should I do mount /dev/sdg2 /boot/efi
Please help to "remove unwanted kernels, unmount again, then repeat the APT invocation".

[fabian]

yes, in your case the partitions are /dev/sdg2 and /dev/sdh2 (those marked as "EFI System" partitions, or "ESP")
