I added the following (temporary) solution based on @student975’s link:
Akonadi (KMail / Kontact / KOrganizer…) fails to start
- The issue is being investigated upstream: 454948 – Akonadi server will not start on fresh install; yields "unknown error"
- If you read this before updating, it seems recommended to backup
ib_logfile0before updating, and restore it after rebooting:cp ~/.local/share/akonadi/db_data/ib_logfile0 ~/.local/share/akonadi/db_data/ib_logfile0.bak pamac update reboot 0 mv ~/.local/share/akonadi/db_data/ib_logfile0.bak ~/.local/share/akonadi/db_data/ib_logfile0 akonadi start
- If you read this after updating and rebooting, you need to create a new
ib_logfile0:touch ~/.local/share/akonadi/db_data/ib_logfile0
Though i personally haven’t updated yet. So if anyone sees anything wrong with it, please don’t hesitate to fix it above.
