Package install fails when apt is in use #103

'apt' may be in use when the scripts wish to install a package. No check is made to ensure it has installed sucessfully or if apt is in use. This may be why there have been issues with emonhub updates.

One solution might be to check if the apt update services are running and if not, stop them. If they are running, need to wait until they have finished.

systemctl status {apt-daily-upgrade.timer,apt-daily.timer}

However, several different things can start apt so it isn't robust (https://saveriomiroddi.github.io/Handling-the-apt-lock-on-ubuntu-server-installations/).
