Error >>>> resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything
If we get this error in Ubuntu while Restarting Network
Here /etc/resolv.conf is a file then move it to /run/resolvconf/resolv.conf.
Solution >>>>
Move the file to /run/resolvconf/
# sudo mv /etc/resolv.conf /run/resolvconf/resolv.conf
Then create the symlink Using command:
# sudo ln -s ../run/resolvconf/resolv.conf /etc/resolv.conf
Then Restart the Network using
# sudo /etc/init.d/networking restart
Or there is a Alternative way
# sudo dpkg-reconfigure resolvconf
This will be solution for the Above error
That's it ...
