When I am trying to update my fedora 22 with update command
sudo dnf update
I am getting following error.
Error: Failed to synchronize cache for repo 'updates' from 'https://mirrors.fedoraproject.org/metalink?repo=updates-released-f22&arch=x86_64': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for https://mirrors.fedoraproject.org/metalink?repo=updates-released-f22&arch=x86_64 [Could not resolve host: mirrors.fedoraproject.org]
