Update: Running the patch.sql.gz script manually (with -f as it does give some errors) appears to have brought my Zabbix installation back to life.
Not sure if the package upgrade wass supposed to do that and skipped it for some reason, or if the schema upgrade was forgotten entirely. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
