Bug #4554
Updated by Junxiao Shi about 6 years ago
ndn-autoconfig-client service cannot register any prefix, because its $HOME is set to `/nonexistent` and therefore cannot access a key chain. Although RIB would accept any signature in the default configuration, it would not accept a registration command with no signature.
Additionally, it’s impossible to use “find home router” stage because there isn’t a key chain to install certificate into.
Environment: Debian Stretch ARMv7, [backport](https://wiki.debian.org/CreatePackageFromPPA) of 0.6.1-ppa1~artful.
