Hi Travis,
Well, if you want to give a shot, you can try to use our work in progress installation script, it may work for you if you are really willing to try.
Be aware, this is WIP, it may not work and we do not recommend the use of this script.
wget https://raw.githubusercontent.com/jaxxzer/companion/setup-clean/scripts/install.sh
chmod +x install.sh
./install.sh
We highly recommend to not use this as a normal installation, buy a normal Raspberry Pi 3B after the quarantine is over and replace the 3B+.
If you don’t want to damage your system, or have unexpected results, please wait for it to be over and buy a new raspberry when possible.
