Kodi 17.4: no upgrade option

[joehc]

Hello

About 2 weeks my raspberry pi would not boot (could not read from sdcard). At that moment I had Kodi 17.4 installed. I was forced to reinstall. But then I remembered I had made a backup image of earlier, back when I had kodi 17.3. I restored the image and the raspberry pi came back online with 17.3.
However, no I can't upgrade to 17.4 anymore. There is not option for it under xbian-config module inside kodi. I have run updates multiple times in the xbian-config module (not sudo apt-get update), but with no luck.

How can I force an upgrade from 17.3 to 17.4?

As I was desperate I tried to see what sudo apt-get update would say and it returned:

Terminal

N: Ignoring file '50unattended-upgrades.ucf-dist' in directory '/etc/apt/apt.conf.d/' as it has an invalid filename extension

Does that have anything to say?

My installation is:

Terminal

cat /etc/os-release
PRETTY_NAME="XBian 1.0 (knockout)"
NAME=XBian
VERSION_ID=1.0
VERSION="1.0 (knockout)"
ID=raspbian
ID_LIKE=debian
ANSI_COLOR="1;31"
HOME_URL="http://www.xbian.org/"
SUPPORT_URL="http://forum.xbian.org/"
BUG_REPORT_URL="https://github.com/xbianonpi/xbian/issues"

Terminal

uname -a
Linux xbian 4.9.58+ #1 SMP PREEMPT Tue Oct 24 17:20:12 CEST 2017 armv7l GNU/Linux

Hope anyone can help

Thanks
