For our small team we tried a cloud-hosted Jira instance (hosted by Atlassian).
Because we all liked it, we now installed a self-hosted version.
The setup works, test emails were sent, everything seemed fine.
To not loose our old issues, I've saved a backup from the cloud-hosted and imported it into our self-hosted instance.
Now I cannot log in to our instance anymore, since the password of the user account is different.
The password used for my Atlassian account does not work, and I cannot send myself a reminder, since the restore seemed to have nuked the SMTP settings...
I have full SSH access to the Linux server running Jira, how can I get back to work?
I.e. retrieve/reset the password of the admin user?
