Using mainline kernel app

[Dantes]

Today I decided to update my kernel to 6.3.9 with the mainline ubuntu kernel/ppa

https://ubuntuhandbook.org/index.php/2020/08/mainline-install-latest-kernel-ubuntu-linux-mint/

 

However this does not work if you have disk-encryption . After rebooting and being greeted by

enter your password, it did not work claiming its missing the dm_mod module. This is the device-mapper

module needed by cryptsetup to create a device in /dev/mapper/

 

After running unmkinitramfs on the 6.3.9 kernel /usr/lib/modules/6.3.9/kernel/drivers/md/dm-mod.ko

was indeed missing.

 

Is this normal for mainline ubuntu kernels ? and does anyone know how to solve this ?

Since you are installing a Ubuntu kernel not an Armbian kernel, (and these are Armbian forums), you should ask your question in a Ubuntu forum.
