Package: yubikey-luks Version: 0.5.1+29.g5df2b95-1 To unlock an encrypted Luks volume that has been setup with yubikey-luks-enroll, you call yubikey-luks-open. However this doesn't work for a couple reason. First the package installs it to /usr/lib instead of /usr/bin, so it isn't in the path. Second it needs expect to run, but that is not declared as a dependency.
