W: Failed to fetch http://ppa.launchpad.net/chris-lea/node.js/ubuntu/dists/vivid/main/binary-i386/Packages  404  Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

Thanks !

The PPA ppa:chris-lea/node.js doesn't contains Vivid packages. Therefore remove the PPA via the command below to prevent downgrading or uninstalling existing packages

sudo apt-add-repository -r ppa:chris-lea/node.js

Execute

sudo apt-get install ppa-purge
sudo ppa-purge ppa:chris-lea/node.js

to remove the PPA without leaving anything behind.

  • Which message do you mean? – A.B. Oct 14 '15 at 19:30
  • raise PPAException("Error reading %s: %s" % (lp_url, reason), e) softwareproperties.ppa.PPAException: 'Error reading https://launchpad.net/api/1.0/~chris-lea: [Errno -3] Temporary failure in name resolution' – Michel Ortega Oct 14 '15 at 19:43
  • Try it again later. The error says, it's a temporary failure in the name resolution. In other words, a network problem. – A.B. Oct 14 '15 at 19:47
