We will no longer support CentOS, Fedora, and Opensuse as installation targets. These are not actively maintained by anyone with commit rights and occasionally cause issues for users as they are not tested during the release process. Rather than have subpar support for an untested operating system, we're removing support for them completely. Users of these operating systems should take a look migration to the docker-based installation method, which will always be tested and supported by the project. Additionally, drop support for Debian 9 as it is now EOL.

Removals
Support for the following operating systems has been removed:
- CentOS 7
- Debian 9 (Stretch)
- Fedora
- OpenSuse
Dokku will no longer provide packages for RPM based systems. Debian 9 users may use new Debian packages, though support is not guaranteed.
All users are encouraged to install Dokku via the Docker-based installation method, or switch to a supported operating system.
Deprecations
Ubuntu 18.04 is now a deprecated installation target. The operating system will be considered EOL by Canonical in April 2023. Users are encouraged to upgrade to Ubuntu 22.04 or consider switching their instllation method to the Docker-based installation method to avoid any disruption in usage.
