I set up a Ubuntu laptop specifically to install Geth/Mist 0.5.2 and have not upgraded since. I want to upgrade to 0.8.1 but need some direction. Am happy to work from terminal, but don't have enough background to do this on my own.
I have searched reddit and StackExchange but haven't seen an upgrade walk through for absolute beginners. I have downloaded Ethereum-Wallet-linux64-0-8-1.zip from https://github.com/ethereum/mist/releases but don't know if I just need to open the wallet icon to update or work from the command line. I have ether in my wallet that I don't want to lose. My keys are backed up. Any help would be appreciated. Thanks.
