i have the same problem with an expired certificate after upgrade, but i am unable to to delete it:
Code:
keytool -delete -alias my_ca -keystore /opt/zimbra/java/jre/lib/security/cacerts -storepass <password>
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect
i tried an administrator password, but i do not recall any other password i set at the time of install. is there any way for me to continue?
