This is due to the removal of the `core.trust_password` option [1], that is used in the `cloud-config` of the workers [2] to set a pre- shared secret later used on the worker [3] to automatically add the remotes. Documentation on alternatives [4] shows it's replaced by two different methods: importing the TLS certificate directly, or through a generated token. Both would require changing the worker charm to adapt to the new method. On suggestion would be to pre-generate a client key and certificate [5], then deploy that automatically, the certificate effectively acting as a pre-shared secret. The certificate is imported like this on the LXD server [6]. And placed on the LXD client (worker unit) in here `/var/snap/lxd/common/lxc/{client.crt,client.key}`. This path `/var/snap/lxd/common/lxc/servercerts` also has a role to play apparently, not sure exactly which one. One alternative approach would be to just stop running armhf test in LXD containers, and boot armhf images in an arm64 cloud, to run them the same way we run all the other architectures.
