Problem description:

Hallo
When I SSH into xbian (on RPI B+), there is a blinking message:

216 packages can be updated.
0 updates are security updates.

However, when running 'apt-get upgrade', it does nothing:

sudo apt-get update && sudo apt-get upgrade

Is it expected behaviour? How should I upgrade to the latest xbian? Unfortunately, I was not able to find an answer on the forum, so sorry if I have missed something ...

Thank you very much,
Dan T.


P.S. When I looked at the latest XBian_Latest_rpi.img, there are different items in /etc/apt/sources.list and /etc/apt/sources.list.d/xbian.list. Mine is (comments excluded):

/etc/apt/sources.list:
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi

/etc/apt/sources.list.d/xbian.list:
deb mirror://apt.xbian.org/mirror.txt stable main rpi-wheezy

which agrees with http://www.xbian.org/faq/. But the XBian_Latest_rpi.img is:

/etc/apt/sources.list:
deb http://mirrordirector.raspbian.org/raspbian/ jessie main non-free

/etc/apt/sources.list.d/xbian.list:
deb mirror://apt.xbian.org/mirror.txt stable main rpi-jessie
