[SOLVED] Updates not working

[syco]

Hi guys,

I have two RPi with the Xbian version 20160406-0,
which tell me both I have several upgrades awaiting
(see attachment with list).

But when trying to update/upgrade those, it just does
not work on both (see attachment with failure).

Does anyone know, what is wrong here?

PS I have not changed anything on the system. I am
just doing the usual update procedures within xbian-config
every four or five weeks.
