Version KMail 5.13.3 (19.12.3) OS Gentoo Linux I have been plagued by this bug for a very long time. Today I found out, that for ages there has been an error message in my mysql/mariadb log- file:
[ERROR] Incorrect definition of table mysql.event: expected column 'sql_mode' at position 14 to have type set ... This is the first time I saw this error, as there is no other application than akonadi using mariadb on my pc and akonadi was never complaining. This mariadb-error could be fixed by running mysql_upgrade (google it to find an explanation, this is due to an incomplete upgrade of the mariadb-package) After fixing the database, kmail has not been showing duplicated mails any longer. Also filters have been working flawlessly. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kdepim in Ubuntu. https://bugs.launchpad.net/bugs/883459 Title: KMail duplicates emails To manage notifications about this bug go to: https://bugs.launchpad.net/kdepim/+bug/883459/+subscriptions -- kubuntu-bugs mailing list kubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
