I installed Redis in Ubuntu 16.04 LTE and during configuration i have to edit redis.conf file, but unfortunately i could not be able to save the file, because file is having read-only access -rw-r--r-- 1 root root 46695 Jan 18 19:57 redis.conf I used chmod 777 redis.conf to get the access writes but it is not happening
chmod: changing permissions of 'redis.conf': Operation not permitted
Thanks in advance for your valuable solution
