Just reinstalled all of these apps, updated them with dnf in the terminal, and removed (actually renamed) the /.local/share/akonadi/ , /.local/share/akonadi_migration_agent/ , and /.config/akonadi/ folders. Still the same problem.
Per "A required background service is not operational" - Akonadi/Kontact/KMail , the fix for me was removing “knotes” and “akonadi-notes” (sudo dnf remove knotes akonadi-notes). From there, I killed all akonadi processes and then ran akonadictl restart - simply running akonadictl stop or restart did not work, because of the weird state akonadi was in; you have to kill the pids for the processes that are running (or just reboot). After that Kontact started working fine for me.
Hope that helps!
Hi, I have the same issue, but I don’t have knotes or akonadi-notes installed, so I can’t remove it? I have tried killing all akonadi processes from system monitor and restarted my PC. I’m also having the same issue on an atomic distro as well.
@mixed-tocopherols thank you. Just like @odyssey-dad I didn’t have those packages installed either. So I installed them and removed them to see whether it would make a difference - it did not. Then I killed all akonadi processes from the system monitor and restarted akonadictl but still the issue remained. A particularly annoying thing is that the Details... button in KOrganizer below the error message is itself also broken 
This isn’t why the error occurs. You need to enable the repository Test Updates to update the library. /lib64/libavformat.so.62
kmail: symbol lookup error: /lib64/libavformat.so.62: undefined symbol: av_exif_parse_buffer, version LIBAVCODEC_62
The developers made a small mistake by including a dependency on a library from the test repository in the stable update.
After updating from the repository, everything works.
Is this how you update testing repository? QA:Updates Testing - Fedora Project Wiki
I tried enabling the repository temporarily. Do I need to update permanently? Or is there a different method?
I think it’s a temporary solution. Today there is another very big update going on.
Ok, should I check again on Monday?
If you don’t need it urgently, you can wait. But I’ve already installed an update of over 3.3 GB. Everything works.
KOrganizer is still not working for me. Am I missing any crucial updates?
Also still not working for me, got this error when running from the terminal:
korganizer: symbol lookup error: /lib64/libkorganizerprivate.so.6: undefined symbol: _ZTIN9PimCommon24WhatsNewTranslationsBaseE
I had a similar situation, only with different libraries. KOrganizer broke after F44 update - #6 by petergrig1969
Just updated from dnf and that error was resolved. But the original problem remains that there are no Akonadi agents available.
I think I have everything.
I think you need to reinstall everything related to these services.

I have done sudo dnf uninstall akonadi*
Then sudo dnf install akonadi-server
Installed KOrganizer and updated from dnf as I was getting the same error as @niels-b
Still the same problem
I typed KOrganizer on konsole. Sometimes, I get the error message shown in your screenshot. Sometimes, I get no message.
Are your services working exactly as they do in the screenshot above on the forum?
I typed KOrganizer (sometimes I get the messages in konsole) and it opens, but I still get the same error message: Cannot connect to the Personal information management service.
I have also tried removing knotes and akonadi-notes, but this was never installed.
