I have a Docker installation of 8.20.0, which today I tried upgrading to 8.21.0.
I used the steps here as a starting point: https://github.com/getsentry/docker-sentry/issues/83#issuecomment-233709532
After running the migrations, updating the Dockerfile to
FROM sentry:8.21-onbuild, removing and rebuilding the containers, and then bringing the containers up, I am greeted by this screen, which I cannot advance past.
I tried adding
SENTRY_BEACON = False to the end of sentry.conf.py and then rebuilding, but it didn’t change anything.
