Just bootstrapped a new 2.7.2 controller on maas cloud.
I noticed that the certificate isn’t signed and reviewing the machine log it seems that some of the intergrations are dated.
2020-02-25 21:10:17 ERROR juju.worker.httpserver tls.go:96 cannot get autocert certificate for "juju.maas.devzero.co.za": 403 urn:acme:error:unauthorized: Account creation on ACMEv1 is disabled. Please upgrade your ACME client to a version that supports ACMEv2 / RFC 8555. See https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430 for details.
Command to bootstrap:
juju bootstrap maas.devzero.co.za juju.maas.devzero.co.za --constraints tags=juju-maas --config autocert-dns-name=juju.maas.devzero.co.za --credential new
