This can happen on Linux and Mac. I personally experienced this on Linux (Ubuntu).
Repo tries to automatically update itself, but when trying to verify the key does not work. To fix this, simply install Gnu Privacy Guard (gpg) and run it again repo:
Linux
- , gpg.
sudo apt-get install gpg - ~/.repoconfig, gpg:
rm -rf ~/.repoconfig repo sync .- .
Mac
- , gpg ( Homebrew).
brew install gpg - ~/.repoconfig, gpg:
rm -rf ~/.repoconfig repo sync .- .
