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

I could not migrate the database until I deleted the tables in Cloudron that caused the problem. After that, everything worked out. These tables were repeated in a dump.

@nebulon Thanks, I was able to migrate the database simply by deleting the repeating table .

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.

Hello! Please tell me how I can add my database to redmine, or connect another, or install something like PHPMyAdmin?
Thanks.
