Ubuntu 24.04, and the two packages that moved

A rebuild onto the new long-term-support release, which was uneventful except for two packages that had been renamed.

the provisioning run, first attempt:

  E: Unable to locate package python-is-python3
  E: Unable to locate package libmysqlclient-dev

both renamed. both found in five minutes. and the third
thing, which was not an error:

  the default OpenSSL is 3.0 and a legacy provider is
  needed for one supplier's certificate chain, which
  failed only when that endpoint was called.

The two package errors stopped the build, which is the good kind of failure. The OpenSSL change did not — it produced a working host with one integration that failed at runtime, discovered a week later, which is the failure mode a rebuild is supposed to surface and only does if the smoke tests actually call the third-party endpoints.
