We are happy to announce a new patch release of CipherMail Email Encryption Gateway. This release fixes a few bugs that could cause problems while updating CipherMail appliances. Users of the Community Edition can find new distribution packages here: https://www.ciphermail.com/downloads-gateway-distributions.html Virtual appliance images are also available for download: https://www.ciphermail.com/downloads-virtual-appliance.html You are advised to create a backup before performing the update on any production system. The full update procedure can be found here: https://www.ciphermail.com/documentation/virtual-appliance-guide/minor-upda… NOTE FOR CUSTOMERS: this time you are also advised to perform the update using these three commands: 1. '$ sudo dnf clean metadata' 2. '$ sudo dnf update' 3. '$ sudo cm-run-playbook' The first command ensures that our patched 'dnf-plugins-core' and 'mariadb' packages are available for installation, the second command updates the packages, and the third command ensures that all configuration gets applied. This *should* all happen automatically, but there may be installations out there that are currently in an inconsistent state due to bugs in previous versions of CipherMail Email Encryption Gateway. We recommend running these commands just to be sure. New virtual appliance images and package archives for offline installation can be obtained through the support portal: https://support.ciphermail.com/user/downloads Customers with a CipherMail Gateway high-availability cluster are advised to update their cluster one node at a time. More information about cluster updates can be found on our documentation website: https://www.ciphermail.com/documentation/cluster-administration-guide/clust… CipherMail Email Encryption Gateway 5.2.2 release notes: **Bug fixes** - Pin MariaDB to custom CipherMail version <= 3:10.3.32-2.1 because MariaDB 3:10.3.32-2 breaks State Snapshot Transfers. [PRO/ENT] - Pin python3-dnf-plugin-post-transaction-actions to the CipherMail-patched version of 4.0.21-4.1.el8. The Red Hat-provided version contains a bug that prevents actions from running under specific circumstances. [PRO/ENT] - Fixed an issue where an interrupted Ansible playbook did not result in a warning in the administrative web interface. [PRO/ENT] - Prevent DNF from restoring the default MariaDB Galera configuration. The default configuration conflicts with the CipherMail-provided configuration, causing the service startup to fail.
