Device : Raspberry-Pi 2 Model B
I upgraded from Wheezy 7.11 to Jessie 8.0
I upgraded using :
apt-get update
apt-get upgrade
apt-get dist-upgrade
I am connected to my eth0
(Wired LAN) when I was upgraded the distribution (Wheezy -> Jessie)
But once I had Jessie installed the same eth0
interface on which I was connected to the Internet started giving this Error:
ping www.google.de
connect: Network is unreachable
I have not configured anything new in my /etc/network/interface
files which I have have kept to the default in Jessie as mentioned in the this Thread on Raspberry Pi StackExchange
Here is my /etc/network/interface
file:
# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
Acquiring IPv4 on Pi
I used the following options:
sudo ifup eth0
and also
sudo dhclient -v eth0
I get the IPv4 address which I can see from ifconfig eth0
eth0 Link encap:Ethernet HWaddr aa:bb:cc:dd:ee:ff
inet addr:10.10.155.187 Bcast:10.10.155.255 Mask:255.255.255.0

I can ping other network devices from my Pi but I cannot connect to the Internet. Why?
dhclient
and disablingdhcpcd
completely.systemd
is suppose to make things simple but apparently not! Also I am adding some edits about thedhcpcd
thing from my pi can you make something out of it?
