First of all I am new to Linux command line. I never worked with it before. My problem is that the command apt-get update will just return:
Err:1 xenial InRelease Temporary failure resolving 'us.archive.ubuntu.com' Err:2 xenial-security InRelease Temporary failure resolving 'us.archive.ubuntu.com' Err:3 xenial-updates InRelease Temporary failure resolving 'us.archive.ubuntu.com' Reading package lists... Done W: Failed to fetch Temporary failure resolving 'us.archive.ubuntu.com' W: Failed to fetch Temporary failure resolving 'us.archive.ubuntu.com' W: Failed to fetch Temporary failure resolving 'us.archive.ubuntu.com' W: Some index files failed to download. They have been ignored, or old ones used instead. My sources.list file looks like this:

I had the same issue. The heart of the problem was an inability to resolve DNS. I was missing my /etc/resolv.conf file.
The contents of it should be:
nameserver 8.8.8.8 nameserver 8.8.4.4 Afterwards, restart the correct interface (mine was lo instead of eth0). You can find it in the /etc/network/interfaces file.
I had the same issue, caused by incorrect DNS settings:
sudo nano /etc/network/interfaces In this file set a correct DNS server: dns-nameservers 8.8.8.8
sudo ifdown eth0 && sudo ifup eth0 I had this same issue, but a slightly different error message. This worked for me:
sudo nano /etc/network/interfaces Find the line for dns-nameserver. If you don't have it, add it like this:
dns-nameserver 208.067.222.222 That is the address for OpenDNS. You can also use 8.8.8.8, which is address for Google Public DNS.
