SOLVED SSH key Redmine

[Neluser]

su - cloudron
ssh-keygen # generates keys under ~/.ssh. keys are part of the backup

Hello, I am creating an SSH key in redmine. But I can’t understand how I can add it to the application.
Can you tell me the sequence of actions or am I doing something wrong?
Thank.

~nano /home/cloudron/.ssh/authorized_keys
Unable to create directory /home/cloudron/.local/share/nano/: No such file or directory
It is required for saving/loading search history or cursor positions.

Hm looks like the nano editor is not working well on those images, however I've just tried it and that appears to only be a warning. Good thing, our next release will contain a webbased fileeditor for such use-cases.

For SSH keys we have some brief info at https://cloudron.io/documentation/apps/redmine/#ssh-keys

@nebulon
I tried to install the key. But the server rejects it. Maybe SSH needs to be turned on somewhere else?
(Test server)
Thanks.

@Neluser I am not really following what's happening. Is the issue that ssh-copy-id cloudron@111.testu1.duckdns.org fails? What is that server? Does it have a user named cloudron ?
