I have a running instance of OpenStack Rocky using LXD hypervisor. Everything appears to be perfectly OK and functional. All basic checks are passing. Uploading images, creating flavours, the network is nicely set up, instances in different series (trusty, xenial, bionic) are running. OpenStack Dashboard is functioning properly. There is not a single detail that would suggest that something is wrong.
However, Juju bootstrap is failing. From what I can get it appears that initial cloud-init setup is failing.
Any ideas how to debug and eventually solve this problem would be highly appreciated.
