I am a beginner at debian.
I hvae just installed debian 7.5.0 amd netinst.
When I execute apt-get update I get errors like Could not resolve 'http.debian.org'
Thus,I changed the mirrors several times in /etc/apt/sources.list but without any result.
I deduced that it is because of the absence of internet connection.
So,I executed ifconfig and ifconfig-a, the output indicates only the loopback no eth0 interface.
However the ethernet card and WLAN card are pretty detected , I checked it through lspci and both cards appear.
I edit / etc / network / interfaces by adding dhcp but it was in vain.
Please, could anybody help me as soon as possible.
Could anyone confirm that internet connection is the problem cause? – user2215151 – 2014-05-09T07:08:32.207
