I ran the update, and turned off the TV as it was running.
When I turned the TV on quite some time later, there was no HDMI signal coming from OSMC.
I rebooted OSMC and find it in SFL.
Buuuut… running sudo apt-get update again, now results in no errors…
Then running sudo apt-get dist-upgrade I get the following errors
Reading package lists... Done

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libboost-filesystem1.55-dev : Depends: libboost1.55-dev (= 1.55.0+dfsg-3) but it is not installable
libboost-system1.55-dev : Depends: libboost1.55-dev (= 1.55.0+dfsg-3) but it is not installable
rbp1-mediacenter-osmc : Depends: libpcrecpp0v5 but it is not installed
E: Unmet dependencies. Try using -f.
