Problems Starting callexecuter
Check the callexecuter logs with the command
sudo journalctl -xeu netrounds-callexecuter
You may see an error like the following:

What has happened is that the netrounds-callexecuter*.deb package was
upgraded without making sure the netrounds-callexecuter systemd service was
stopped and disabled. The database is in the wrong state; it needs to be restored from
backup, and the upgrade needs to be repeated.
Do the following to disable and stop the netrounds-callexecuter
service:
sudo systemctl disable netrounds-callexecuter sudo systemctl stop netrounds-callexecuter
Web Server Does Not Respond
Check the apache logs with the command
tail -n 50 /var/log/apache2/netrounds_error.log
If you see the following error, it means that Control Center version 2.34 is running on Ubuntu 18.04, that is, Control Center has not been successfully upgraded. The solution is to upgrade Control Center to a later version as described in this document.

Restarting the netrounds-* services with
sudo systemctl start --all "netrounds-*" apache2 openvpn@netrounds
produces the following message:
Failed to start netrounds-agent-ws-server.service: Unit netrounds-agent-ws-server.service is masked. Failed to start netrounds-agent-daemon.service: Unit netrounds-agent-daemon.service is masked.
This means that the services mentioned have been masked in the course of the package removal process and require manual cleanup. The cleanup procedure is shown below:
sudo apt-get purge netrounds-agent-login sudo find /etc/systemd/system -name "netrounds-agent-*.service" -delete sudo systemctl daemon-reload
