bash script to update mynodebtc. It does exactly all steps from the upgrade guide. You should expect to SSH, download it, run it and wait for it to upgrade and finalize with a reboot.
SSH into your mynodebtc and then:
wget https://raw.githubusercontent.com/pysiak/mynodebtc-upgrade/master/update.sh
chmod 0750 update.sh
./update.sh
./update.sh
Do let me know if you find it useful. Thanks!
