As i tried to setup env for installation of rockpi4b,but i got python errors.
Help me to solve this.
Rockpi4B is not supporting in ubuntu 22.04
What kind of mindflow it is? Please use English
For me, continental is enough 
However, if you expect some help, a little more info is necessary. What is a setup env(iroment)? One would expect that you downloaded some image (which?) and wrote it to an SD-card or some other boot medium?
