I installed solana cli on my Ubuntu 20.04 to work as validator node. I am a beginner and I made some mistakes along the way and the validator did not start. I used the command :
sh -c "$(curl -sSfL https://release.solana.com/v1.9.12/install)"
Now, I want to start all over again from scratch and for that I want to know that deleting the folder 'solana' is enough or do I have to take some more steps?
