System does not start after upgrade to 8.1.2

I just tried to upgrade to 8.1.2, which failed for some reason. I do not remember the exact error message. Some filesystem could not be mounted. After restart LibreELEC tried a recovery which failed for a similar reason. Now the system always boots into debugging shell with the error message:

Error in prepare_sysroot: mount_common: could not mount /dev/SYSTEM

How can I fix this?

Which version did you have before, and on what kind of hardware?

That was version 8.1.1 on x86 hardware (AMD E-450).

I tried to do the upgrade again by copying KERNEL, KERNEL.md5, SYSTEM and SYSTEM.md5 to /storage/.update. The update does indeed restart but ends with the error message:

Error in check_update: mount_common: Could not mount /flash/SYSTEM

Checking /flash/SYSTEM I fould that the file was only 148 MB while the file on /storage/.update was 212 MB.

There is no need to unpack the .tar update file yourself as we do it automatically (since ~4 years).

You can also use LE settings to update via the GUI
