This is an announcement rather than a support request. I’m a Debian Developer and I have just packaged and uploaded to packages that should be of interest to some NitroKey users:
ocf-cc as a command line executable, with working bash completion.
- Debian ITP bug #967943
This includes full featured bash completion.
- Debian ITP #967907
If Ubuntu users are interested, I could upload these packages to a Launchpad PPA for easy installation.
