Recovering from the OmniFocus error “No key in slot”

In versions of OmniFocus that support encryption, you may encounter an error “No key in slot n”. We’re still trying to track down the root cause of this problem, but in the meantime to recover from this error, choose the set of steps below to follow only on a device that is not experiencing the problem and displays no errors when syncing. You should only need to follow these steps on one device:

In OmniFocus 2.6 for Mac or later

If OmniFocus 2.6 or later is syncing without error but another device is displaying “No key in slot n”:

  1. Quit OmniFocus on all devices except the Mac that is not displaying an error.
  2. Choose Replace Server Database… from the OmniFocus File menu and confirm the action by clicking Replace on the dialog that appears.
  3. When OmniFocus for Mac replaces the server database, it tells all other clients to download this fresh copy the next time they sync. This should clear the error on all devices.

In OmniFocus 2.15 for iOS or later

If OmniFocus 2.15 or later is syncing without error but another device is displaying “No key in slot n”:

  1. Quit OmniFocus on all devices except the iPhone or iPad that is not displaying the error.
  2. Open OmniFocus Settings and tap Backups in the Database section.
  3. Tap Back Up Now. You will see the timestamp just above that button change to reflect the current time. The new backup you’ve just made contains an un-corrupted version of your database.
  4. Tap the timestamp to open the Backup Info screen, then tap the red Revert to This Backup text.
  5. When OmniFocus reverts to a backup, it automatically overwrites the copy of your database on the server and tells all other clients to download this fresh copy the next time they sync. This should clear the error on all devices.
