[error ] SQL [00000004] Failed: Duplicate entry 'x-no-relay' for key 'gns', Query Size: 170, Query: "ALTER TABLE `names` ADD UNIQUE INDEX `gni` (`guid`(16), `nameid`), ADD UNIQUE INDEX `gns` (`guid`(16), `namestring`), DROP INDEX `guidnameid`, DROP INDEX `guidnamestring`"
[error ] KDatabase::I_Update() query failed: "Duplicate entry 'x-no-relay' for key 'gns'", query: ALTER TABLE `names` ADD UNIQUE INDEX `gni` (`guid`(16), `nameid`), ADD UNIQUE INDEX `gns` (`guid`(16), `namestring`), DROP INDEX `guidnameid`, DROP INDEX `guidnamestring`
[error ] K-1216: Cannot update to schema v69, because the "names" table contains unexpected rows. Certain prior versions of the server erroneously allowed these duplicates to be added (KC-1108).
[error ] K-1220: To fix the excess rows, use `kopano-dbadm k-1216`. Consult the manpage and preferably make a backup first.
[error ] K-1221: Alternatively, the server may be started with --ignore-da to forego the schema update.
[warning] WARNING: Unable to upgrade database from version 8.5.9.2153316352.68 to 8.5.9.2153316352.70
[warning] You can force the server to start with --ignore-database-version-conflict
[warning] Warning, you can lose data! If you don't know what you're doing, you shouldn't be using this option!
After the recent update the server stays offline.
The “kopano-dbadm k-1216” command seams to fix the problem for me.
