<!DOCTYPE html><html><body>I'm upgrading an old system running KDE 4.14, to 20.08. The mail is stored in ~/Mail (which is where I want to it to remain). After a lot of messing about, I finally discovered the Akonadi Maildir resource which showed the mail folder structure under ~/Mail. I then deleted the default Local Folders resource, since it had no obvious use alongside the Maildir resource.<br><br>Since then, Kmail displays a fatal error soon after starting, every time:<br><br>"The email program encountered a fatal error and will terminate now. The error was:<br>Timeout trying to get lock."<br><br>Any ideas on how to stop the error happening? It makes Kmail completely unusable.<br><br>I've tried reinstalling the Local Folders resource, but it makes no difference.<div style='white-space: pre-wrap'>--<br>David Jarvie<br>KAlarm author, KDE developer<br></div></body></html>
