While upgrading Chia on Linux is not as simple as on Windows, it is still relatively easy.
First we need to stop the Chia service
Open up a terminal, navigate to the chia-blockchain folder, and stop the services
chia stop -d all
Now we will need to download the latest files using git.
git checkout latest
git reset --hard FETCH_HEAD
Now that we have the latest files, we can install the new version.
sh install.sh . ./activate chia init
Upgrading the GUI is similar to the above process. Should be able to copy and paste the following commands.
cd chia-blockchain-gui git fetch cd .. chmod +x ./install-gui.sh ./install-gui.sh cd chia-blockchain-gui npm run electron &
The last command will launch Chia GUI.
