terminal – Permission denied (publickey). Oracle Cloud VM


I just lately made a modification on this file: /and so forth/ssh/sshd_config by including this line: CASignatureAlgorithms +ssh-rsa (to unravel issues with Github Actions: https://github.com/appleboy/ssh-action) however since I can not hook up with my server.

This machine is an Oracle VM working on the newest model of Ubuntu. I’ve the chance through Oracle to entry the storage of the machine (to change any file) however no entry through ssh.

So I attempted to take away : CASignatureAlgorithms +ssh-rsa from the sshd_config file, however after a reboot, it’s nonetheless unattainable to entry the server through ssh. I’ve tried all of the strategies instructed right here (https://askubuntu.com/questions/311558/ssh-permission-denied-publickey) however none of them works.

Right here is the complete log when typing this command : ssh -vvv -i Downloads/key.key ubuntu@1.1.1.1 (With the true ip after all being completely different than 1.1.1.1)
