Akonadi_migration_agent stops

Help
1

Hi Community,

Since the last KDE update, a pop-up window with “akonadi_migration_agent” appears when KDE is launched, but it always stops at 66% progress. After restarting the system, the same thing happens again (see screenshot).

Kmail and Kontact can no longer be started. Error message (translated from German):

A necessary background service is not working (Ein notwendiger Hintergrunddienst funktioniert nicht)

What can I do to solve this problem?

The problem has now occurred on a second laptop. I don’t have the “hanging pop-up” there, i.e. it closes again after a few seconds. But what is fatal is that Kontact or Kmail can no longer be started.

The error must obviously have something to do with the “akonadi_migration_tool”. Does anyone know of a bug report for this?

As a workaround (on the first laptop), I restored a system backup (as of 01.08.2025). With this backup, I have no problems with Kontact or Kmail, i.e., they run correctly. But of course, not updating the system is not a permanent solution.

This bug report could be related https://bugs.kde.org/show_bug.cgi?id=508382

It does not say anything about the migration tool but also seemed to have happened at a recent update.

Weirdly I have updated Neon last Sunday as well and have no issues at all.

Thanks for letting me know.

I have problems with Kontact/Kmail not starting on two out of three systems. One system runs smoothly, even after a recent update.

I have opened a bug report at Bug 508594

It’s also clear that Kontact isn’t working, since “akonadi control” is always stopped according to “akonadictl status.” Something is blocking it.

This looks similar to a post a couple of days ago Akonadi not working since update

Might even the same person who reported the bug I linked to earlier

I was able to solve it. After looking through the bug reports you linked to, I noticed that deleting the “knotes” package helped one user.

Deleting knotes solved the problem.

$ sudo apt purge knotes

After restarting the system, I was able to start Kmail/Kontact again. So far, I have not noticed any negative effects from deleting the “knotes” package.

Thanks for your tips.

Greetings

Michael

Maybe also add this as a comment to your bug report.

It might help to find the actual cause
