Can't activate Unity?

I installed Unity 2019.3.0f3 through the standalone installer.

Then I activate my license:

xvfb-run -a --error-file '/var/log/xvfb_error.log' \
    --server-args='-screen 0 1024x768x24 +extension RANDR' /opt/Unity/Editor/Unity \
    -logFile -quit -nographics -batchmode \
    -serial "${serial}" -username "${username}" -password "${password}" \
    -projectPath "${PROJECT_DIR}"

I get this output which sends me mixed signals:

No valid Unity Editor license found. Please activate your license.

It says that the license was activated successfully but also reports that no Editor license could be found.

Trying to build my project then fails: /opt/Unity/Editor/Unity -batchMode -nographics -quit -projectPath "${PROJECT_DIR}" -executeMethod "${build_method}"

LICENSE SYSTEM [20191226 19:26:43] Information: Unity license returned.

This previously worked in 2019.2.9f1. (with a very slightly different procedure)

What am I to do?

Current line of thinking: does Unity (2019.3+) now require the Hub to manage licenses?

Looks like I’m right so this thread should really be on the Beta forums. This can be closed.
