Just doing the update, upgrade and installation of the packages give me this error. It is trying to change create a symbolic link on the /boot partition that mount shows is vfat:
/dev/mmcblk0p1 on /boot type vfat (rw)
which does not support symbolic links I suppose.
Is yours also vfat?
How to prevent it trying to create that link?
But besides this it seems to work.
