Hello there,

I just had to go through this issue, was this ever released?


$ sudo landscape-config --computer-title $(hostname) --account-name standalone  -p <token> --url https://lds.int.hrizn.cloud/message-system --ping-url http://lds.int.hrizn.cloud/ping
enabled

This script will interactively set up the Landscape client. It will
ask you a few questions about this computer and your Landscape
account, and will submit that information to the Landscape server.
After this computer is registered it will need to be approved by an
account administrator on the pending computers page.

Please see https://landscape.canonical.com for more information.


The Landscape client communicates with the server over HTTP and
HTTPS.  If your network requires you to use a proxy to access HTTP
and/or HTTPS web sites, please provide the address of these
proxies now.  If you don't use a proxy, leave these fields empty.

HTTP proxy URL: 
HTTPS proxy URL: 

Landscape has a feature which enables administrators to run
arbitrary scripts on machines under their control. By default this
feature is disabled in the client, disallowing any arbitrary script
execution. If enabled, the set of users that scripts may run as is
also configurable.

Enable script execution? [y/N]: 

You may provide an access group for this computer e.g. webservers.

Access group: 

You may provide tags for this computer e.g. server,precise.

What worked was running the client then performing the registration:

ubuntu@juju-b096f0-92-lxd-0:~$ sudo /usr/bin/python3 /usr/bin/landscape-client &

Then killed the PID and restarted the service normally:

ubuntu@juju-b096f0-92-lxd-0:~$ sudo systemctl restart landscape-client.service
