Thanks Awesome Donkey! I had to perform a clean install, but after that the installation went without a hitch. Unfortunately, in the process I accidentally deleted my notes on how to configure the UFW for DLNA. I know 52100 – 52200 need to be open, furthermore SSDP 1900 also needs to be open, but I don’t remember the specific commands. Hopefully, a thorough google search will provide an answer.
Thanks AD!
