I'm following this tutorial and this is what I'm trying
ssh-copy-id -i ~/.ssh/id_rsa.pub remote_host It says Permission denied (publickey,password).
I've also tried ssh -v remote_host and verified that

You should give the private key to ssh-copy-id or no key at all as mentioned in the synopsis of the command (from manual page):
ssh-copy-id [...] [-i [identity_file]] [-p port] [-o ssh_option] [user@]hostname or no key at all (it will copy all the keys in standard location in that case). Using the following should do the job:
ssh-copy-id -i ~/.ssh/id_rsa remote_host If it will not be helpful, please run
ssh-copy-id -i ~/.ssh/id_rsa -o LogLevel=DEBUG3 remote_host and update the question with the output to investigate more.
