Can't update or install plugins - No adress associated with hostname

Hi

When I'm trying to install or update a plugin I get (it's the same thing with all plugins):

"Something wicked happened resolving 'packages.omv-extras.org:http' (-5 - No address associated with hostname)
Failed to fetch http://packages.omv-extras.org…lt-ddclient_1.0.4_all.deb Something wicked happened resolving 'packages.omv-extras.org:http' (-5 - No address associated with hostname)"

Does anybody no what can be wrong?

I'm on OMV 2.2.13

Thank you

Thanks for your reply. Unfortunately it doesn't fix the problem. I've tried with my isp's dns and other with no luck.

Any other ideas? Maybe some config file that has been corrupted? Or some magic ssh commands that can help with the trouble shooting?

Thanks. "Router's ip" - do you mean the gateway ip-adress as dns?

I've tried the dns that the isp sets in the router. Ive tried Google's. I've tried both static and DHCP. Everything without any luck

Where is the network config file located?

You have to try to be able to learn

I've attached a screenshot

No luck. This how it has been configured when it worked. I don't need restart the server between changes or...?

I looked in the network config file and I don't see anything out of the ordinary. Maybe sharper eyes and more knowledge can see something

"The loopback network interface
auto lo
iface lo inet loopback

# eth0 network interface
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp
dns-search WORKGROUP
pre-down ethtool -s $IFACE wol g
iface eth0 inet6 manual
pre-down ip -6 addr flush dev $IFACE"

This was over my head

No traceroute. I don't use any VPN right now.

traceroute google.com
google.com: Namn eller tjänst okänd
Cannot handle "host" cmdline arg `google.com' on position 1 (argc 1)

In my mind something is blocking the servers access to the DNS. I've tried with the server as DMZ and DNS set in network adapter - no luck. That would rule out the router messing things up. I've never touched the firewall in OMV

I don't know what that is I have OpenVPN installed but not in use at the moment. Now I have disabled it but no change

There is only one adapter physically connected. Do you mean I should remove it from the interface tab?

Tried to unistall OpenVPN an got a massive error message. It started like this:

"Failed to execute command 'export LANG=C; apt-get --yes --auto-remove --purge remove openmediavault-openvpnas"

Tell me if you want to see the rest of it
