When upgrading UAR 12.5.x to version 12.6.x you may encounter error: "Unable to initialise etpki" during the upgrade process.
This will cause the upgrade to stop running and the igateway process will not be able to start.
In some instances the permissions for the CAPKI directory (/opt/CA/SharedComponents/CAPKI) can be incorrectly set.
Check the permissions of the directory by running the following two commands:
The permissions for the directory should read: drwxr-xr-x
If the permissions are not set correctly please change them using the command: chmod -R 755 CAPKI
Run the: ls -la command again and confirm that the permissions now read: drwxr-xr-x
Start the igateway process as root:
cd to $IGW_LOC
Run: ./S99igateway start
If the igateway process now starts successfully wait about 5 minutes for all of the igateway process to resume running then logon to the UAR UI and check to confirm that the Upgrade processes have resumed running.
If you encounter different problems or resetting the CAPKI directory permissions does not resolve the problem please open a support case with UAR Support.
