Thank you Michael, I've just updated from 239-15 to 240-2; but, unfortunately, none of the problems were solved.
Also, followed your instructions, but: root@local:~# udevadm trigger root@local:~# update-initramfs -u update-initramfs: Generating /boot/initrd.img-4.19.0-1-686-pae Fatal: raid_setup: stat("/dev/disk/by-id/ata-Maxtor_6Y060M0_M0000000") run-parts: /etc/initramfs/post-update.d//runlilo exited with return code 1 But this time, I was able to reboot and finish downgrading to 239-15 OK.
