[BUG 3.4.0] sed: -e expression #3, char 93: unknown option to `s'

[tvarsis]

Infos:

• Docker version: 19.03.11
• Docker-compose version: 1.24.0
• Operating system (Docker host): Ubuntu 18.04

Did a normal git pull and updated with docker-compose as always.

Expected behavior:

• Upgrade should work and not throw errors

Actual behavior:

sudo docker logs zammad_zammad-init_1
sed: -e expression #3, char 93: unknown option to s' sed: -e expression #3, char 93: unknown option to s'
sed: -e expression #3, char 93: unknown option to s' sed: -e expression #3, char 93: unknown option to s'
sed: -e expression #3, char 93: unknown option to s' sed: -e expression #3, char 93: unknown option to s'

Which leads it to get stuck in a restarting loop and not finishing.

Steps to reproduce the behavior:

• Was running 3.3.0-26 and upgraded to 3.4.0-2. Also tested to change versions to 3.4.0.4 and 3.3.0.31 and same error on all of them.

Found the issue. It was a space and a comment behind the postgres username in the env file that made the whole init script crash.
