I just want to install some plugins on my OMV and I got the following error: "The list of sources could not be read" (vid. attached picture)
And then I just realized that I can't even run the "apt-get update" command. I get the following message: "E: Ütköző értékek vannak megadva a(z) Check-Valid-Until beállításhoz ezen forrásra vonatkozóan: http://archive.debian.org/debian/ jessie-backports
E: A források listája olvashatatlan."
Means (something like this)
"E: Percussive values are given to setting Check-Valid-Until belonging this source: http://archive.debian.org/debian/ jessie-backports
E: List of sources could not be read."
I've tried a lot of (but not all) suggestions mentioned here: Problems with sources.list?
If someone would send me a sources.list file that will be awesome.
P.S.: I'm using Debian 8 release 3.16.0-10-686-pae
and OMV 3.0.99 (Erasmus)
Hope someone can help,
