I’m following the guide to upgrade the monitoring agent https://www.digitalocean.com/docs/monitoring/how-to/upgrade-legacy-agent/
However when I run
sudo apt-get purge do-agent
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
I run the command as instructed and then re-run the first command but that results in
