@bigbucketboy Could be known_hosts problem?

Did you check that?

It sounds like this is the cause of the issue:
https://issues.apache.org/jira/browse/GUACAMOLE-1315

Related issue here:

The 'hack' will be needed until the Guac folks resolve this issue: https://issues.apache.org/jira/browse/GUACAMOLE-1504

It looks like Guacamole only supports ssh-dss and ssh-rsa, and both have been disabled in Ubuntu.

DSS was removed 8 years ago and RSA has been deprecated, so hopefully Guacamole updates sometime soon.

In the meantime a workaround is adding “HostKeyAlgorithms +ssh-rsa” to the end of /etc/ssh/sshd_config on the Ubuntu machine and restart sshd.

@BrutalBirdie and @robi thanks for your guys help! @robi your suggestion by adding the new line in the /etc/ssh/sshd_config this worked perfectly and gave me my command line gui in Guacamole. I’ll mark this as solved. Thanks for your thorough explanation as not only how to fix it but also as to why it wasn’t working in the first place. Thanks again guys!

top right dropdown.

@robi I don't think I have that option maybe that's why I can't do it. Here is a screen grab.

@bigbucketboy check the gear icon

@bigbucketboy You will have to click the gear icon and select ask a question, then the topic will have a unsolved tag, then you can select a comment as the answer aka. mark this as solution.

@bigbucketboy is there a way to modify ssh_config file? Its read only and I tried to chmod the file, and guessing its a container thing. I edited the host OS, but guessing the container needs to be modified.. I can't SSH into the Ubuntu system.. Not a linux/container guy

[girish]

@skippsterr Why do you want to edit the sshd_config file in the container? I think the original solution was to edit the sshd_config in the target ubuntu machine that you will connect to (not Cloudron server).
