What to do if you have a technical problem with OCS:
1. Search the forum
. You can do this from the Advanced Search Page
or from our Google Custom Search
, which will search the entire PKP site. If you are encountering an error, we especially recommend
searching the forum for said error.
2. Check the FAQ
to see if your question or error has already been resolved. Please note that this FAQ is OJS-centric, but most issues are applicable to both platforms.
3. Post a question
, but please, only after trying the above two solutions. If it's a workflow or usability question you should probably post to the OCS Conference Support and Discussion
subforum; if you have a development question, try the OCS Development
I am trying to perform a Full Package upgrade from OCS 126.96.36.199 to OCS 188.8.131.52 and receive the following error when trying to perform the DB upgrade from either the web interface or CLI:
ERROR: Upgrade failed: DB: Duplicate entry 'REVIEW_ACK-0-1' for key 2
Can this problem be related to another issue experienced on this OCS site, logged here: viewtopic.php?f=3&t=5980

This is likely caused by an upgrade on an already failed upgrade (thus on a fractured database). Please try restoring from backup to a stable state, then trying to upgrade again.
