Akonadi_migration_agent disturbing

I have two newly installed debian 13 with KDE. After a power outage the main desktop displayed the Akonadi_migration_agent at 33% for hours. Searching akonadi did not provide any info to help or seemed excessively hacky.

After several reboots it started asking for multiple passwords: router, kwallet, calendar maybe some others. Hitting cancel just reasked. I finally gave one a password but I don’t remember to which app. I went to work. When I came back I could use LibreOffice finally. BUT the computer would not connect to the router/internet.

What a hassle. Can I trust I’ll be able to connect and this won’t happen again. I can’t be locked out for hours or days because of a temporary electrical issue.

What’s going on?
