I wonder why skeiron.org gives an error; really I've tried it many times and it works well except for in the logs to have a minor line saying about bzip but it updates fine and apps install fine too...

If it isn't working for you then you have somehow managed to mangle your gpg key or not added the repo correctly...


In worst-case scenario like its been mentioned multiple times just go and navigate using a web browser to the URL to get whatever packages/dependencies required...
