I am trying to use hashcat with intel i5 and 2 AMD GPUs

[bikitizd0g]

The OS is Kubuntu 21.04 which comes with hashcat.  

But on the frontpage of Hashcat website it reads I must install RadeonOpenCompute (ROCm)

I tried to install it but it requires python 3.8 not python 3.9 which comes with Ubuntu 21.04

Should I install Ubuntu LTS instead?

The error message I am getting is 

rocm-gdb : Depends: libpython3.8 but it is not installable E: Unable to correct problems, you have held broken packages.

Advices welcome! Should I try to install python3.8 in addition to python3.9 OR should I install Kubuntu LTS?
