Hi,

For quite some time already, the creation of Digital Ocean agents has become quite brittle and barely usable.

I'm using the "Ubuntu Docker 18.09.2~3 on 18.04" image as a base, and the installation of the Java JVM for bootstrapping the agent fails (almost all the time, but not always) with:

WARNING: Installing java failed.
java.lang.Exception: Installing java failed.
	at com.dubture.jenkins.digitalocean.DigitalOceanComputerLauncher.launch(DigitalOceanComputerLauncher.java:184)

In the agent log, one of the last messages we see is:

E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

Any idea what could be causing this?

Thanks for any feedback,
Damien
