Deploying shellbox to staging failed because the httpd-fcgi image configured was still using "www-data" user. The httpd-fcgi image was updated to use numerical UIDs in 2.4.38-3 but that version was never published to the registry. I tried to build 2.4.38-4 just now and it fails because of test.sh not working:
