Hi,

I’m running Ubuntu 18.10 in my droplet. But I haven’t updated it in a while. When I tried to run do-release-upgrade I getting “Please install all available updates for your release before upgrading”.

But when I tried to run sudo apt update && sudo apt upgrade -y getting these in the terminal:
