I had same issue couple days ago. My problem was name of public key, I just rename public key to id_rsa and it works again.

Try with ssh -vvv root@IP address and see what is your problem with login.

Do you have multiple ssh-keys on your computer?
you might wanna check if you have added your ssh key to your agent with ‘ssh-add -L’

When I created my very first droplet, I encountered the same error.

The solution was:

1. Generate a keypair in localhost using “ssh-keygen” and press <Enter> for the rest.
2. Add a public key to your account settings with name “id_rsa.pub”.
3. Create the droplet after <1>. Make sure to check the checkbox to use existing pub key.
4. After droplet creation, log in as usual “ssh root@<droplet_ip>”

Hope it helps.

We are getting same issue since few days. Anyone found solutions?

I had same issue & I found this link.
https://medium.com/@hidace/how-to-ssh-into-a-digitalocean-server-after-getting-permission-denied-publickey-error-77b687c2880d

I’m having a very similar experience, except I’m not sure I ever managed to log in! Everything ends in Permission denied (publickey). e.g.

ssh-copy-id oolong@[my IP address]
/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: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
Permission denied (publickey).

I’m using Mint, fwiw.

Meets the same issue , anyone who has solved it ?

I have the same problem.
I tried everything in digitalocean

rothmann doesn t work

have same problem , any news? i copy the pub key i generated via git bash then i did ssh root@etc but dosnt work… says same Permission denied (publickey) for root

Same issue. when trying with ssh root@ip_add, it says Permission denied (publickey).

Same issue. It used to be successful at the first time. But then ends up the same issue.

Hello there. Any updates with this question?
I ran into the same issue today.
I have used my ssh key for few weeks.. and it worked fine. But today I can’t enter to my droplet.
I use ssh root@<droplet_ip> and every time get Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
Even if I use ssh root@<droplet_ip> -i path/to/my/key it doesn’t work.
I checked everything. I checked that ssh-add -L gets my public key and file on droplet /root/.ssh/authorized_keys (through browser Console access) has the same value. Seems everything is ok. But it doesn’t work now. I don’t know why. Maybe the problem on my side… but what exactly?

Hello,
Don’t forget modes and ownership in source and destination:

0700 user:user for .ssh
0644 user:user for .ssh/authorizedkeys and .ssh/knownhosts
0600 user:user for .ssh/id_rsa

It’s very important and if is not like that you may have this error
