Well if you want to mine crypto with Ubuntu here's what I think you should do
Firstly you'll need:
Powerful computer
High-performance graphics card
Enough RAM
Fast internet connection

Install necessary packages with `sudo apt-get update` and `sudo apt-get install openjdk-8-jre`. Choose mining software like CGMiner, EasyMiner, or MultiMiner.

Configure with your Bitcoin wallet and join a mining pool like Slush Pool or Antpool. Run CGMiner with `cgminer --pool pool-url --user username --pass password`.
