You updated the docs in getsentry/sentry-docs#11807 in order to use multiple .env-files.
You also updated the wrap-up in #3523.

But it is still missing to use both .env-files in the installation script: https://github.com/getsentry/self-hosted/blob/master/install/_lib.sh#L14
If this is missing, i am not able to update sentry without editing .env.custom
