Hi.

I upgraded mariadb today to 11.8.6 and now akonadi doesn't want to start
anymore.

I append the verbose log from akonadictl and the mariadb error log.


Best regards
Matthias

Changes:
 mariadb (1:11.8.6-0+deb13u1) trixie; urgency=medium
 .
   [ Otto Kekäläinen ]
   * New upstream maintenance release 11.8.6. For details about fixes please see
     https://mariadb.com/docs/release-notes/community-server/11.8/11.8.6
   * For details about fixes in 11.8.5 please see
     https://mariadb.com/docs/release-notes/community-server/11.8/11.8.5
     and the security notices:
     - CVE-2025-13699
     - CVE-2026-21968
   * For details about fixes in 11.8.4 please see
     https://mariadb.com/docs/release-notes/community-server/11.8/11.8.4
   * The version 11.8.4 was skipped in Debian (and Ubuntu) as it has a severe
     regression causing partial data deletion when using the DELETE statement on
     MyISAM or Aria tables under specific conditions (MDEV-38068)
   * Already existing plugins marked ready for general availability by upstream
     in this release: uuid_v4, uuid_v7 and inet4
   * Upstream 11.8.5 included fix to MDEV-36556 about upgrades failing from 10.4
     when encryption enabled (Closes: #1122811)
   * Add debian/source/local-options to suppress WolfSSL line ending errors
   * Patch new upstream test main.alter_merge to allow 'from Debian'
   * Fix path to mariadb-server.README in mariadb-secure-install
     (Closes: #1127863)
   * Add preliminary upstream patch to fix MDEV-38811 that affected Akonadi and
     any other use case that relies on 'skip-grant-tables' (Closes: #1127431)
   * Update patch statuses and Forwarded fields to aid patch maintenance in
     future new upstream version updates
   * Update server trace to include new 'new-mode' value 'FIX_INDEX_LOOKUP_COST'
   * Salsa CI: Apply several fixes already in use on debian/latest branch and
     which are needed on this branch as well due to external changes since
     August 2026, most notably Salsa CI switching to be sbuild based
 .
   [ Daniel Black ]
   * MDEV-37411: Re-enable AIO in Debian to fix earlier incomplete fix that was
     done after new upstream 11.8.3 release introduced innodb_linux_aio
   * MDEV-15502: With recent changes in upstream systemd, the tmpfiles are now
     required, otherwise starting MariaDB would fail on error:
     "cannot create /run/mysqld/wsrep-start-position: Directory nonexistent"
