+If the error message says palera1n.zip, you are running an outdated version of palera1n and need to update using "git pull". If this doesn't work, reclone the palera1n repository with "cd && sudo rm -rf palera1n && sudo git clone https://github.com/palera1n/palera1n.git". Otherwise, this error most likely indicates a problem with your internet connection, and you simply need to retry running palera1n again.
