Welcome, @KaunoSeptintasFortas
The “not found” error message means the environment that the job is running in has a configuration problem. The root issue is usually some dependency problem (not installed, or has incorrect permissions).
You can install tools directly in the Galaxy application and check the box to use dependencies resolvers (Admin → Tool Management) or you can batch the work with helper scripts (example → Hands-on: Hands-on: Galaxy Tool Management with Ephemeris / Galaxy Server administration).
