[James Page]

nova depends on netcat, which is no longer in Ubuntu main, but there are no references in the code to this tool.

James, sorry I messed this up a bit. I just uploaded a new snapshot without your change. The snapshot drops nova-network though so this bug is fixed in it.

[Corey Bryant (corey.bryant)]

Moving this to fix released. The nova-network binary package was dropped in focal and netcat was a direct dependency of it.
