--- Comment #16 from Martin Schnitkemper <martin.schnitkem...@nexgo.de> --- I have now run the update on two systems and in both cases akonadi no longer starts. I didn't get the "unknown error" error, but the file "ib_logfile0" was missing after the first login. A "touch $HOME/.local/share/akonadi/db_data/ib_logfile0" as suggested here several times was not a solution because after the second logon I had 3200+ entries in mysql.err like | [ERROR] InnoDB: Page [page id: space=0, page number=7] log sequence number 1447482201 is in the future! Current system log sequence number 1378510903. | [ERROR] InnoDB: Your database may be corrupt or you may have copied the InnoDB tablespace but not the InnoDB log files. Please refer to https://mariadb.com/kb/en/library/innodb-recovery-modes/ for information about forcing recovery. A "recovery" was not an option for me because it seems complicated to me, is only insufficiently described in the MariaDB knowledgebase and I am not sure if it solves the problem at all. I had already completed the update to mariadb 10.8.3 last week and also updated the structures with "mariadb-upgrade --socket=/run/user/$(id -u)/akonadi/mysql.socket", it came therefore only the "KDE Gear 22.04.2" update with akonadi and its accompanying components. Based on the experience of the first system, I copied now the "ib_logfile0" file to a safe place before updating the second system. After the file was missing again after the update and the first logon, the easiest solution for me was to copy the file back after the update and restart akonadi. It also survived a reboot. My recommendation is therefore to back up the file before an update or restore it from a current backup. If it has already happened then it also helps to delete (or rename) the "db_data" folder and start new with a "mariadb-install-db --datadir=$HOME/.local/share/akonadi/db_data --basedir= /usr". The question remains (and here I see the real problem) why akonadi or one of its components removes the "ib_logfile0" file on the first logon after the update. -- You are receiving this mail because: You are watching all bug changes.
