Technical details

  • Kolibri version 0.14.5
  • Operating system: Kolibri packaged OS for RPi
  • Any and all.

Hello @cjackson, I see this is the second time you have the same problem ( Got the following error in Kolibri today: ) what is weird because we haven’t seen anywhere else. I guess it is due to the big size of your database together with the limited capacity of the RPi, because the problem again seems to be a data corruption when executing big database changes.

Please, try to apply the fix Lingy recommended in Got the following error in Kolibri today: or send me your db in private so we can study it.
