Landscape client can't register with Landscape server

Question

I have Landscape installed with a self-signed certificate and my own Certificate Authority. I have the CA certificate installed in my browser, and I can access the Landscape website at https://landscape.sahfos.dev/ without TLS issues.

On a client machine, geoserver.sahfos.dev, I have the CA cert installed into /etc/ssl/certs/, and hashed, and

$ openssl s_client -CApath /etc/ssl/certs/ -connect landscape.sahfos.dev:443
...
Verify return code: 0 (ok)

works, as does

$curl https://landscape.sahfos.dev/message-system
Landscape message server

However,

$ sudo landscape-config --computer-title "Geoserver.sahfos.dev" \
--account-name standalone \
--url https://landscape.sahfos.dev/message-system \
--ping-url http://landscape.sahfos.dev/ping --silent

fails.

$ sudo tail -n 12 /var/log/landscape/broker.log

That error 77 indicates a problem with the certificate chain, yet curl doesn't have a problem itself.

Does anybody understand why the client can't establish a secure link to the server?

Answer 1

Never mind. I'm trying to do this the hard way. Simply adding the certificate file to /etc/landscape/client.conf works:

ssl_public_key = /etc/landscape/server.pem

as in https://help.landscape.canonical.com/LDS/QuickstartDeployment16.03, rather than adding the certificate itself with base64 encoding as suggested at https://help.landscape.canonical.com/LDS/Installation (which also suggests using the non-existent bootstrap.conf file.
