Rockpro64 not booting anymore after latest apt upgrade / init not found

[arnaudf]

Dear Armbian community,

 

Yesterday morning, after apt upgrade my Rockpro64 not boot (the white and red led stayed lit).

After some tries I managed to get a boot again but I now have a "init not found" error, as you can see on the screenshot.

 

What have been done so far :

- Install an Ubuntu as "debug" platform

- Follow the recovery steps from Armbian website

- Put on eMMC storage a 5.15.63 by copying the files from Armbian

- Check if UUID was consistent between partition, boot config, ... ==> this is the case

- Made a fsck : no errors found

 

==> I would like to try this : https://askubuntu.com/questions/910218/sbin-init-no-such-file-or-directory-not-able-to-boot-ubuntu-desktop, but need to have a boot prompt (how to get it ?)

 

If somebody has any other hint... I would take it

I have spent hours on the setup of my Rockpro64, I would avoid to reinstall it.

 

Regards.

I finally found the issue :
For an unknown reason the /lib->/usr/lib symlink in rootdir disappeared. It becamed a directory with "firmware" and "modules" subdirs.

I then copied the actual lib content to /usr/lib, then delete /lib and made again the symlink. This solved the problem.
