I want to uninstall my geth, but I can't. How could I do it
Also, if I'd like to update my geth version, how could I do it?
Edit (added info according to the comment of @Ismael)
I'm using Ubuntu 16. I installed it from PPA, executing these commands:
sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum
Best Answer
You can upgrade your client geth with normal debian/ubuntu commands
To uninstall
To remove the ubuntu ppa (only do this after you have removed ethereum package)
If you have run geth then you probably have $HOME/.ethereum and $HOME/.ethash directories with your keystore and blockchain data. If you used the wallet probably you want to make a backup of $HOME/.ethereum/keystore. If you no longer want to use ethereum in that machine you can remove both directories.
