HI. I have tried installing klayout in 2 scenario. First - sudo apt-get install klayout . While running klayout Error pops up as application crashed. Second - downloaded .deb file from website, while unpacking it shows an dpkg error (I have installed libruby and libpython). Ubuntu version 20.04 Please help

The .deb error means that you don't have some of the required dependencies. Can you try running

sudo apt-get update --fix-missing
sudo apt-get install
