We are receiving Unknown error 111 opening Common Object Repository when running etautil command on a RHEL Provisioning Server.
Provisioning Server on Linux 14.5.x / v15
One possible cause would be if the value stored in the registry is empty or incorrect. To dump out the entire registry, you can use the command eCSoption /r.
One such key of many for example would be the following but check for others that might be blank as well:
Provisioning Server 14.5.x
Provisioning Server v15
The value should be the Provisioning Server hostname so please set the value for the key as mentioned in the following documentation link:
Provisioning Server 14.5.x
Provisioning Server v15
