Could not resolve host: mirrorlist.centos.org; No address

Every time I try I see a message that says "cannot resolve hostname". From the terminal, I tried: $ ping www.google.com unknown host google.com $ ping 8.8.8.8 network is unreachable output of 'ip addr list' . 2016.08.06 01:54:30 - OpenVPN > RESOLVE: Cannot resolve host address: localhost: nodename nor servname provided, or not known the problem is in your system. A system MUST be able to resolve name "localhost". You don't find this problem in Tunnelblick because it contacts OpenVPN management at 127.0.0.1, but Eddie approach is more correct. I don't run a full 19.04, so maybe I'm wrong about the libnss-resolve not being available. Try sudo apt-get install libnss-resolve and see what happens. If nothing, you can edit your hosts line to have the "resolve [!UNAVAIL=return]" befoer the dns -- That's really all I know that installing the package does anyway. – ubfan1 May 18 '19 at 15:11
