Hi all,

I have a few contradictory questions.

1. How to upgrade the 3.x version?

2. Is it possible to migrate (downgrade) the lists from mailman 3.x to 2.1?

3. If so, what would be the best way to do that?

My mailing list server is running on a CenOS-7x with postgreSQL and the following mailman packages:

django-mailman3 1.3.5 mailman 3.3.2 mailman-hyperkitty 1.1.0 mailman-web 0.0.3 mailmanclient 3.3.2 postorius 1.3.3

We have ~200 lists with more than a decade of history.

So you have installed Mailman 3, apparently following https://docs.mailman3.org/en/latest/install/virtualenv.html. There is a caveat. Current released versions of HyperKitty (I don't see your version above) don't work with mistune >= 2.0.0.

This is https://gitlab.com/mailman/hyperkitty/-/issues/431, fixed by https://gitlab.com/mailman/hyperkitty/-/merge_requests/379 but not yet released.

If your installed mistune is not 2.0.0rc1, you can work around this with this patch ``` --- a/hyperkitty/lib/renderer.py +++ b/hyperkitty/lib/renderer.py @@ -4,7 +4,7 @@ from django.conf import settings

import mistune from mistune.plugins.extra import plugin_url -from mistune.scanner import escape_html, escape_url +from mistune.util import escape_html, escape_url

class MyRenderer(mistune.HTMLRenderer): ``` Or you can downgrade mistune with ``` pip install mistune==2.0.0rc1 ``` in your virtualenv.

To answer your questions, to migrate your lists, you use `mailman import21` and to migrate archives, `mailman-web hyperkitty_import`. Give these commands with the `--help` option for more info.

Downgrading lists from Mailman 3 to Mailman 2.1 is not currently possible. There is no inverse to `mailman import21`. You can export a HyperKitty archive as a mbox to use as input to Mailman 2.1s bin/arch.

Thanks Mark. You're right it was installed in a virtualenv using pip. I can't see the mistune package, maybe it wasn't a requirement for that version of mm3. 1 Package Version 2 ------------------- ---------- 3 aiosmtpd 1.2.4 4 alembic 1.5.3 5 arrow 0.17.0 6 asgiref 3.3.1 7 atpublic 2.1.2 8 authheaders 0.13.0 9 authres 1.2.0 10 bleach 3.3.0 11 blessed 1.17.12 12 certifi 2020.12.5 13 cffi 1.14.4 14 chardet 4.0.0 15 click 7.1.2 16 cmarkgfm 0.5.2 17 cryptography 3.3.1 18 decorator 4.4.2 19 defusedxml 0.6.0 20 Django 3.0.12 21 django-allauth 0.44.0 22 django-appconf 1.0.4 23 django-compressor 2.4 24 django-extensions 3.1.0 25 django-gravatar2 1.4.4 26 django-haystack 3.0 27 django-mailman3 1.3.5 28 django-picklefield 3.0.1 29 django-q 1.3.4 30 djangorestframework 3.12.2 31 dkimpy 1.0.5 32 dnspython 2.1.0 33 docutils 0.16 34 falcon 2.0.0 35 flufl.bounce 3.0.1 36 flufl.i18n 2.0.2 37 flufl.lock 3.2 38 gunicorn 20.0.4 39 HyperKitty 1.3.3 40 idna 2.10 41 importlib-resources 5.1.0 42 lazr.config 2.2.3 43 lazr.delegates 2.0.4 44 mailman 3.3.2 45 mailman-hyperkitty 1.1.0 46 mailman-web 0.0.3 47 mailmanclient 3.3.2 48 Mako 1.1.4 49 MarkupSafe 1.1.1 50 networkx 2.5 51 nose 1.3.7 52 oauthlib 3.1.0 53 packaging 20.9 54 passlib 1.7.4 55 pip 21.0.1 56 postorius 1.3.3 57 psycopg2-binary 2.8.6 58 publicsuffix2 2.20191221 59 pycparser 2.20 60 Pygments 2.7.4 61 PyJWT 2.0.1 62 pyparsing 2.4.7 63 python-dateutil 2.8.1 64 python-editor 1.0.4 65 python3-openid 3.2.0 66 pytz 2021.1 67 rcssmin 1.0.6 68 readme-renderer 28.0 69 requests 2.25.1 70 requests-oauthlib 1.3.0 71 rjsmin 1.1.0 72 robot-detection 0.4 73 setuptools 39.2.0 74 six 1.15.0 75 SQLAlchemy 1.3.23 76 sqlparse 0.4.1 77 typing-extensions 3.7.4.3 78 urllib3 1.26.3 79 uWSGI 2.0.19.1 80 wcwidth 0.2.5 81 webencodings 0.5.1 82 wheel 0.36.2 83 Whoosh 2.7.4 84 zipp 3.4.0 85 zope.component 4.6.2 86 zope.configuration 4.4.0 87 zope.deferredimport 4.3.1 88 zope.deprecation 4.4.0 89 zope.event 4.5.0 90 zope.hookable 5.0.1 91 zope.i18nmessageid 5.0.1 92 zope.interface 5.2.0 93 zope.proxy 4.3.5 94 zope.schema 6.0.1
