This whole story doesn't make much sense to me. You switched to a new virtual server because Mailman 2 isn't supported but imply that Mailman 3 is, but you can't get support from your vendor? Do you mean that *Python* 2 is not supported but *Python* 3 is? Then, as far as I can tell on my hosts, Mailman 3 does not use a lot more resources than Mailman 2.1 to process email, because it's basically the same processing model. By "doing anything," do you mean posting to lists? Migrating lists? Creating and managing lists with Postorius? Migrating archives? Accessing archives and posting via HyperKitty? Python 2 is *unsupported* and likely to have security issues (in particular, it probably allows SSL/TLS connections now considered insecure). Mailman 2 is also end-of-life, and may have security issues (although Mark continues to accept patches and even fix them occasionally, he keeps promising to stop "soon"). You're asking for endless hurt if you get into trouble with Mailman 2. (I don't think it's likely except maybe a botnet will take your virtual server over for Bitcoin mining or DDoS attacks, but if it happens it will be bad.) Like Mark, I recommend that you at least let us try to help you to figure out why the virtual server fails to run Mailman 3. Are you sure the new virtual server will handle the load of Mailman 2? Maybe it's just too small for the job of handling mailing lists. If you're not willing to upgrade, you're going to need to install Python 2, and a few packages. You'll need to get support from your virtual server provider and/or the OS vendor for that, we can't help you. It's possible that they're EOL at the OS vendor as well. (I was looking to install Python 3.8 on my Debian system to support a user who's stuck on 3.8 for corporate QA reasons, and surprise! it's not on their principal mirrors any more. There are Linux distros that never supported Python 2, they were on Python 3 from the start.) Python 2 is deeply embedded in some ecosystems, so most likely your OS vender still delivers the most recent Python 2.7. But you can be sure Python 2-compatible packages are bitrotting in most cases, including those that support Mailman.
