I've 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 edited /etc/network/interfacesl by adding DHCP but it was in vain.

    So your question is rather about how to get your network connection to work than the apt-get, right? Maybe it is better to rephrase it as such?

  • I can not understand the problem actually. The feature was that apt-get failed according to commands I tried I deduced that I have a pb with my internent connection but I am not sur about it

  • Try doing ifconfig. What does it show? Does it show an inet addr associated with your network interface? If that works, try ping 8.8.8..

  • is your network device installed correctly? Give lspci and see if it lists any network device. If that doesn't work, do dmesg and see if any network device is listed in the entire thing.
