What does this commands show?
curl https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered
If it outputs lots then just the last few lines will do.
@jbudd We did have a similar report of no output at all just a few weeks ago, but I can't immediately find it.
