I purchased world of goo from the Ubuntu Software Center about a month back and it works fine. Recently though when I perform a sudo apt-get update I get the following output.
W: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/world-of-goo/ubuntu/dists/precise/main/binary-amd64/Packages The requested URL returned error: 401 W: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/world-of-goo/ubuntu/dists/precise/main/binary-i386/Packages The requested URL returned error: 401 E: Some index files failed to download. They have been ignored, or old ones used instead.
Can someone explain what all this means and what I can do to have it properly updated?
Edit: I ran the following at the bash command line
/etc/apt/sources.list.d/*.list | grep ppa
Which yielded the following output relevant to world of goo:
deb https://private-ppa.launchpad.net/commercial-ppa-uploaders/world-of-goo/ubuntu precise main #Added by software-center; credentials stored in /etc/apt/auth.conf
Edit 2: I have submitted a bug report to software-center on launchpad and written to the publisher.
