This is confusing:
Running Cloud-init v. 18.4
Using snappy module, getting warning: "snappy module will be dropped in 18.3 release"

Do we travel back in time?

Actual log:

[ 70.192446] cloud-init[2169]: 2019-02-01 14:43:34,232 - cc_snappy.py[WARNING]: DEPRECATION: snappy module will be dropped in 18.3 release. Use snap module instead

Start by locating the cc_snappy module and the snap module referenced in the warning, then reproduce the logged behavior on the affected Ubuntu environment. Determine whether snappy is still supported and make the warning match that status; the issue is done when the resulting behavior and message are consistent and the ssh-authkey-fingerprints failure is understood.
