Forks that keep the upstream nanoclaw repo under a non-origin remote name (typically `upstream`, with `origin` pointing at the user's fork) hit "git fetch origin channels failed" when adding a channel, because the fork doesn't carry the channels branch. New setup/lib/channels-remote.sh walks `git remote -v` for a url matching qwibitai/nanoclaw, auto-adds `upstream` if none matches, and honors NANOCLAW_CHANNELS_REMOTE as an override. Wired into the four add-*.sh scripts that setup:auto invokes (discord, telegram, whatsapp, teams).
