Pentaho 6 Spoon Error - pentaho

Question

I use Pentaho 6 (6.0.1.0-386).
My system is Ubuntu 14.04 LTS
Linux LT0124 3.13.0-95-generic #142-Ubuntu SMP Fri Aug 12 17:00:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
Java version:
java version "1.8.0_101"
Java(TM) SE Runtime Environment (build 1.8.0_101-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)
I am able to open Pentaho and select specific transformation. But when I try to execute it I am getting following error:
An unexpected error occurred in Spoon:
org.pentaho.di.trans.TransMeta.isAlwaysShowRunOptions()Z
java.lang.NoSuchMethodError:

Could you please let me know what is the root cause?

This is jar versions conflict. Take a look onto 'kettle-engine-6.1-XXX.jar' where is 6.1 is release version. In your case should be not less then 6.0.
