Signatures cannot be updated after signature systems have become corrupted in the configuration database.


Signatures cannot be updated.


Signature systems are corrupted in configuration database. This can occur after upgrading to v11.6.0, v11.6.1, or v12.0.0.


Delete signature systems with an ID greater than 38, and re-add them by performing a signature update. You can delete these signature systems by running the following command: mysql -u root -p$(perl -MPassCrypt -nle 'print PassCrypt::decrypt_password($_)' /var/db/mysqlpw) -e "DELETE FROM PLC.NEGSIG_SYSTEMS WHERE system_group = ''"

Fix Information

Signature System data corruption is corrected upon upgrade, and Signatures can be subsequently upgraded.
