Hi Everyone, I have been trying unsuccessfully for several weeks to install Mailman3 on a new Ubuntu 20.04 LTS server. First I tried to just use the Ubuntu packages, which is MM3 version 3.2.2. Unfortunately Ubuntu 20.04 also uses Python 3.8 which has a compatibility issue with MM 3.2.2. There is a bug submission submitted to the Ubuntu team.
Next I tried to use the virtualenv method, as that was recommended for production anyway by Mailman installation documentation. I couldn't get that to work either, as there is again some known issue between one of the django packages and another python package called 'six'.
Has anyone been able to get Mailman3 running stable on Ubuntu 20.04? What installation method did you use? At this point, I'm really tempted to just stay at MM2 until the Ubuntu packages get sorted out. I've also considered just closing the Gitlab repo and trying to set it up manually. But I feel like it isn't worth all the trouble.
Thanks in advance for your thoughts.
