Update does not install

Hi geeks and nerds,

I am on 2015.12-1 on RPi2.
When manually checking for an update, it downloads the update and prompts to restart and install it.
Then I only get a black screen and it does nothing. As my SSH connection is still alive the reboot is not executed.
When I then reboot manually, it boots up just fine, however I’m still on old version, trying again leads to the same result.

Log files after reboot:

Any hints?

if you got access to ssh

do sudo apt-get update && sudo apt-get dist-upgrade -y

should start the update process from terminal

Yes, that worked fine. Thanks a lot!
