Error on build

[nat-n]

Attempting to build as is resulted in:

E: The repository 'http://security.ubuntu.com/ubuntu cosmic-security Release' does not have a Release file.
E: The repository 'http://archive.ubuntu.com/ubuntu cosmic Release' does not have a Release file.
E: The repository 'http://archive.ubuntu.com/ubuntu cosmic-updates Release' does not have a Release file.
E: The repository 'http://archive.ubuntu.com/ubuntu cosmic-backports Release' does not have a Release file.
ERROR: Service 'fah-client' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y bzip2' returned a non-zero code: 100

Switching to Ubuntu 18.04 (which is the current LTS) seemed to fix it.

Thanks for the feedback.

I fixed it by migrating to latest Ubuntu version (with also an update of the fahclient version).
