Hi
2 weeks ago I format my pc to ubuntu 17.10.Then I try to log in my server but it refuses.
- I create rsa keyin my pc. and put it from droplet panel first but it refuses again (permission denied) then tried DO ssh setting (how to use ssh key) , it refuses again
- I changed ssh_config, add password authentication pubkey auth, rsa auth, it refuses permision denied
- I remove .ssh folder from root and user in droplet, it refuses again
output /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 2 key(s) remain to be installed – if you are prompted now it is to install the new keys Permission denied (publickey).
or

This worked for me:
chmod go-w ~/ chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
https://www.howtogeek.com/168156/fixing-authentication-refused-bad-ownership-or-modes-for-directory/
DO host from droplet console root and user
chmod 700 .ssh chmod 600 .ssh/authorized_keys
copy ur pub with wget cat publickey > .ssh/authorized_key (root and user)
solved
can u write ur do and local ssh_config pls?
Adding your ssh key to your account makes it available on the droplet creation page so it can be inserted into new droplets when they are created. It is not applied to your existing droplets.
If you were attempting to switch to password authentication you will also want to make sure that AllowRootLogin is set to true unless you are using a different user.
This effectively deletes all reference on your droplet to your keys and will completely prevent any login with a key since there is no key to match it up against.
Once you’ve created your private/public keypair on your local machine this tutorial can be used to help you place it properly on your droplet. The relevant section is “How To Copy a Public Key to your Server”.
