No akonadi connection to Mysql after last update

Hello,

I did a package update last night and akonadi stops launching. Kontact will not start, this is the "akonadictl start" command :

Re: No akonadi connection to Mysql after last update

What's your qt5-base version? qt5-base 5.15.2+kde+r215-2 was released yesterday with a "emergency" patch to fix MySQL compat. If the update didn't include that but included the new mariadb release this could the issue and you should check your system for updates again.

Re: No akonadi connection to Mysql after last update

I have these errors with akonadi regularly, it is starting to be quite annoying.
I have not been able to find any solution so far other than dumping all all of it (by removing both ~/.local/share/akonadi* and ~/.config/akonadi*) and starting over.
I would love to see if there is any other solution.
My system is up to date and qt5-base version is 5.15.2+kde+r215-2.

Re: No akonadi connection to Mysql after last update

Does something crash in the background, do you get coredumps? https://wiki.archlinux.org/title/Core_d … _core_dump

Re: No akonadi connection to Mysql after last update
