I created a container in the GUI called container1. Then I tried to install an application in the same configuration page but I get a spinning "busy" wheel that continues indefinitely (~hour). If I close the screen and come back it says that no packages are installed.

So I opened a terminal and tried to run the command line equivalent. First I tried to list my containers:

$ libertine-container-manager list
xenial

Obviously, xenial is different from container1.

Then I tried a basic usage from the documentation. I tried to install a package like this:

libertine-container-manager install-package -p fish -i container1

It says that there is no container id with that name.

The I tried with no -i flag:

libertine-container-manager install-package -p fish

Then it says it is unable to acquire the dpkg lock. Nothing else was using it I don't think. Same result with adding -i xenial.

I thought maybe it was a permissions issue but when I prepend sudo to the above command it says I should not be using sudo with Libertine.

How do I use Libertine to install apps?
