When I was creating a new gpg directory in my new home partition, I got this warning:
gpg: WARNING: unsafe permissions on homedir '/home/boosung/.gnupg'To resolve this warning, I simply ran chmod 700 .gnupg/.
7 indicates that the user has read, write, and execute permissions. The first 0 indicates that the group has no permissions. The second 0 indicates that other users have no permissions either.
