Hello everyone,
I had Zammad 5.3 running in Docker / Portainer for 2 years. After an upgrade to version 6.x with several major changes seems too complicated, I want to detach Zammad from Docker and migrate it to a separate VM.
To follow the upgrade path correctly, I want to install Zammad version 5.3 on Ubuntu 22.04 LTS using apt. However, an apt-cache policy zammad does not list Zammad version 5.3 or does not let me install it. What am I doing wrong or does version 5.x simply no longer exist in the apt channel?
