mailman/mailman3: Please drop dependency on Python2 (demoting mailman)

[Matthias Klose]

mailman (depending on Python2) is currently seeded in supported-misc-servers. Please consider demoting mailman, and promoting mailman3-core instead.

Status changed to 'Confirmed' because the bug affects multiple users.

[Bryan Quigley (bryanquigley)]

Afaict this should be targeting mailman3 (not sure what happened to package mailman3-core).

The mailman (2) packages has been marked as legacy and only supports python2.

Looking at deps for apt install mailman3 --no-install-recommends I do find the majority of packages not in main for bionic though... The obvious problems I see from it are Zope and sqlite...

Dear Bryan,

When I first packaged mailman3 parts into Debian, I chose mailman3-core (source & binary name) for the server and with Jonas, we chose mailman-suite (source & binary name) for the web package providing the django settings to provide hyperkitty and postorius.

We realized quickly that users were confused by this naming convention. They were expecting the server to be mailman3. We chose to rename the source & binary package from mailman3-core to mailman3, hence the disappearance of mailman3-core.

Theoretically, mailman3 binary package doesn't depend on python2, but mailman3-full binary package depends on mailman3-web and thus on postorius and hyperkitty and django-mailman3 which are python2 packages.

Upstream did release alpha versions of postorius/hyperkitty/django-mailman3 1.2.0, which are full python3 (with dropping of python2 support). As soon as these release are stable, they'll be packaged into debian, and should hence come in ubuntu soon after (thanks to transition).

Cheers.

mailman3-core has been superseeded by mailman3.

demoted again, no MIRs for dozens of dependencies

This is meant to be a dup of 1775427 but LP fails to accept that (due to the massive amount of target tasks or subscribers - most likely bug 925937).

Therefore just marking this one invalid to get it off everyones radar
