wget http://www.google.com/ Resolving www.google.com (www.google.com)... failed: Temporary failure in name resolution. wget: unable to resolve host address `www.google.com'
ping google.com
ping: unknown host google.com
This is a normal DNS setting error, please ping 8.8.8.8 to find out your network works or not first
If ping 8.8.8.8 works, then you should run below command via ssh root:
echo 'nameserver 8.8.8.8' > /etc/resolv.conf;
After that, please try wget again, it should no such error in future.
