Hi J., > Did you follow the upgrade guide? > https://www.cyrusimap.org/3.6/imap/download/upgrade.html
obviously I did not read it as carefully as you might expect. Else I would not have run into any trouble. On the other hand, the upgrade to 3.6 is so tricky that only a full-time-admin can invest this much time especially considering this in a Debian way of Upgrading: Are you sure, that the Debian install-script is shutting down cyrus carefully and not starting it in post-install? Some years ago, the upgrade was failing, because I shot down cyrus manually and the pre-install-script was expecting a running cyrus to be able to shutsdown. So beside of the cyrus documentation you have to consider the maintainers thoughts on this topic. In the end, if you want to use cyrus on Debian I'd recommend to remove the Debian packages and install vanilla from tarball. Then you have to follow the 3.6-upgrade docs "only". And you know, you are on your own. Then it's also an easy thing follow the guide: 1. Upgrade 3.2.6-2+deb11u2 to 3.2.10 (where there is no package in the repository) 2. Upgrade 3.2.10 to 3.6.latest (as Дилян suggested) --Chris ------------------------------------------ Cyrus: Devel Permalink: https://cyrus.topicbox.com/groups/devel/Tc0e863bae9053445-M0554d38fb6ca8da0f596faea Delivery options: https://cyrus.topicbox.com/groups/devel/subscription
