Kalendar isn't starting the GUI (segfault, something with Akonadi)

[bennypr0fane]

The Kalendar app never starts when I click the launcher icon.
Here is the output from starting it in the terminal:

 ~  kalendar

Can you make anything of these errors?

Akonadi (KMail / Kontact / KOrganizer…) fails to start

• The issue will be fixed in 22.04.3: 454948 – Akonadi server will not start on fresh install; yields “unknown error”
• In the meantime, you need to create a new ib_logfile0 in order to allow Akonadi to start.
• Since MariaDB has also been updated with this update, you may want to upgrade Akonadi’s database (this can take a while).

touch ~/.local/share/akonadi/db_data/ib_logfile0
akonadictl start
mariadb-upgrade --defaults-file=~/.local/share/akonadi/mysql.conf --socket=/run/user/$(id -u)/akonadi/mysql.socket

---

Otherwise: KDE - ArchWiki

Thank you. the fix suggested here in the announcement did not work. I reset Akonadi for a clean start as per your link to ArchWiki and then continuining here, this worked and I have Kalendar starting again!
