I recently migrated from Ubuntu 12.04LTS to 14.04 LTS .I had issues with my 12.04 so I did a factory restore and then upgraded to 14.04.My system is upgraded to 14.04 with no issues but The first thing I see is after restarting a pop up comes system problem detected.If I cancel it I don't see any issues,however the real problem is when I try to install nodejs using the below link---
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
then I see some weird erros---------

E: Some index files failed to download. They have been ignored, or old ones used instead.
I did try with below solution
sudo rm -vf /var/lib/apt/lists/*
but it again gives this error
rm: cannot remove ‘/var/lib/apt/lists/partial’: Is a directory
Please help me on this as I am struggling with this.
