Hi, Is it possible to upgrade from Debian 11 to Debian 12 with Mailman3 installed on Debian 11? I specify that I want to stay in the Debian repositories, not a "hand" installation of MM3. I tested on a specific server. It was long and tedious but it seemed to me that it was working. In fact everything seems to work except the archive management :-( Here is the procedure followed: Stopping MM services Backup of the database (PostgreSQL) and the base MM directory Switch server from Debian 11 to Debian 12 and restart migrate the database from PG 113 to PG 15 (pg_upgradecluster 13 does this very well) Modify the file /etc/mailman3/mailman.cfg with a URL reference "postgresql://" instead of "postgres://" (see https://lists.mailman3.org/archives/list/ mailman-users@mailman3.org/thread/CU6YU44V4WLRJI3WJH2VBWO2HCUF4YEA/) update MM3 databases with "mailman-web migrate" restart MM3 and MM3-web With that MM3 works but not the archiving management! Note that there are no real error messages in the logs… In fact when we go to a list archive, we have pretty waiting wheels... infinite :-( The only reference in mailman3-web.log: [pid: 1429|app: 0|req: 12/12] NNN.NNN.NNN.NNN () {68 vars in 1445 bytes} [Mon Dec 18 16:35:56 2023] GET /hyperkitty/list/admin@ teledetection.fr/ => generated 37443 bytes in 37 msecs (HTTP/1.1 200) 7 headers in 221 bytes (1 switches on core 1) If you have any solution...
