I'm completely new at this, trying to deploy a meteor app. I'm trying without much success at this point to add node 0.10.40 to Ubuntu 14.04. What I have managed to do is add a bunch of non existing repositories.
How do I get rid of them? These are the repositories I would like to get rid of:
Err https://deb.nodesource.com trusty/main amd64 Packages
HttpError404
Err https://deb.nodesource.com trusty/main i386 Packages
HttpError404
Ign https://deb.nodesource.com trusty/main Translation-en
W: Failed to fetch https://deb.nodesource.com/v0.10.40/dists/trusty/main/binary-amd64/Packages HttpError404
W: Failed to fetch https://deb.nodesource.com/v0.10.40/dists/trusty/main/binary-i386/Packages HttpError404
Where did I add these repositories to? They are not in /etc/apt/sources.list.d. In that folder I do see a repository added via the command add-apt-repository ppa:chris-lea/node.js
grep -r --include '*.list' 'deb.nodesource.com' /etc/apt
to find out in which file the lines are.
