** Description changed: [Environment] Bionic python3-httplib2 | 0.9.2+dfsg-1ubuntu0.2 [Description] maas cli fails to work with apis over https with self-signed certificates due to the lack of disable_ssl_certificate_validation option with python 3.5. [Distribution/Release, Package versions, Platform] cat /etc/lsb-release; dpkg -l | grep maas DISTRIB_ID=Ubuntu DISTRIB_RELEASE=18.04 DISTRIB_CODENAME=bionic DISTRIB_DESCRIPTION="Ubuntu 18.04.5 LTS" ii maas 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all "Metal as a Service" is a physical cloud and IPAM ii maas-cli 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS client and command-line interface ii maas-common 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS server common files ii maas-dhcp 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS DHCP server ii maas-proxy 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS Caching Proxy ii maas-rack-controller 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all Rack Controller for MAAS ii maas-region-api 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all Region controller API service for MAAS ii maas-region-controller 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all Region Controller for MAAS ii python3-django-maas 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS server Django web framework (Python 3) ii python3-maas-client 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS python API client (Python 3) ii python3-maas-provisioningserver 2.8.2-8577-g.a3e674063-0ubuntu1~18.04.1 all MAAS server provisioning libraries (Python 3) [Steps to Reproduce] - prepare a maas server(installed by packages for me and the customer). it doesn't have to be HA to reproduce - prepare a set of certificate, key and ca-bundle - place a new conf[2] in /etc/nginx/sites-enabled and `sudo systemctl restart nginx` - add the ca certificates to the host sudo mkdir /usr/share/ca-certificates/extra sudo cp -v ca-bundle.crt /usr/share/ca-certificates/extra/ dpkg-reconfigure ca-certificates - login with a new profile over https url - when not added the ca-bundle to the trusted ca cert store, it fails to login and '--insecure' flag also doesn't work[3] [Known Workarounds] None [Test] # Note even though this change only affects Python3 # I tested it with Python2 with no issues and was able to connect.
