You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
juju-deployer : Depends: python3-juju-deployer but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
jenkins@juju-osci1-machine-16:~$
Although manually resolving dependencies is a work-around, if there are dependency declaration issues in the packaging, future package upgrades will be predictably problematic.
