Upgrading & Connecting to Devnet
Debian Packages:
Debian Repository: First, set up and update the alpha Debian Repository for your platform with the following commands:
sudo rm /etc/apt/sources.list.d/mina*.list
echo "deb [trusted=yes] http://packages.o1test.net $(lsb_release -cs) alpha" | sudo tee /etc/apt/sources.list.d/mina-alpha.list
sudo apt-get update
Then, install the package(s) that you need:
Mina Daemon: sudo apt-get install --allow-downgrades -y mina-devnet=3.2.0-alpha1-7f94ae0
Archive Node for devnet now has it's own package. If you are running an older version and wish to upgrade,
we recommend that you first remove the previous version and then install the new version with:
sudo apt-get remove mina-archive
