xbian rpi3, latest image: udate error

[Nachteule]

This is only warning. I checked this, this small issue was born between July 8 and July 15 this year

To remove this warning please edit file /etc/apt/sources.list.d/xbian.list and remove doubled entry of rpi2-jessie

Before (wrong xbian.list):

Terminal

deb mirror://apt.xbian.org/mirror.txt stable main rpi2-jessie rpi2-jessie
### deb mirror://apt.xbian.org/mirror.txt staging main rpi2-jessie rpi2-jessie
### deb mirror://apt.xbian.org/mirror.txt devel main rpi2-jessie rpi2-jessie

After (fixed xbian.list):

Terminal

deb mirror://apt.xbian.org/mirror.txt stable main rpi2-jessie
### deb mirror://apt.xbian.org/mirror.txt staging main rpi2-jessie
### deb mirror://apt.xbian.org/mirror.txt devel main rpi2-jessie

and run sudo apt-get update again
