While generating gpg key, I was getting error where the screen automatically goes off and the control immediately comes back stating below

gpg: cancelled by user
gpg: Key generation canceled.

-bash-4.2$ gpg --gen-key

         0 = key does not expire
      <n>  = key expires in n days

      <n>m = key expires in n months
      <n>y = key expires in n years

GnuPG needs to construct a user ID to identify your key.

Real name: svc_WellsFargo
Email address: user@domain.com.com
Comment:
You selected this USER-ID:
    "svc_WellsFargo <user@domain.com.com>"

Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key.

gpg: cancelled by user
gpg: Key generation canceled.

Solution Applied: It bugged a lot and finally googled the solution (putting it here for the sake of everyone)
As a root user, run below command

$ chmod o+rw $(tty)

Happy reading !!!
