A number of users have reported issues with the Windows Subsystem for Linux (WSL) server in versions of Ubuntu 18.04 and Debian 9.0, which may be further complicated by upgrades to these distributions. The issue is not due to Windows itself but to the Ubuntu and Debian packages. Therefore, a clean installation of Ubuntu 18.04 or Debian 9.0 may be attempted as a workaround. The issue may also be experienced by using `wsl -v` to verify if the issue is present on the operating system. The issue does not appear to be present in Ubuntu 17.10 or Debian 8.0. A work around is to use a different WSL server, such as `wine`, `nvidia-tesla`, or `nvidia-docker`. The issue has been addressed in Twisted 22.4.0rc1.
A regression in the Python 3.6+ version of the Twisted Web HTTP 1.1 server has caused the server to crash upon encountering certain malformed HTTP requests. This regression may affect users of Twisted Web at the level of the Twisted Web HTTP 1.1 server. This issue has been fixed and Twisted Web HTTP 1.1 server now correctly handles malformed requests.
The Python 3.6+ Twisted Web HTTP 1.1 server has been upgraded to use the new deprecation system. This adds a deprecationWarning() method to the twisted.web.server.HTTPServer class. If you have
