Q:

Cannot access PPA ppa:langdalepl/gvfs-mtp on Ubuntu 14.04

I followed the recommendations in the following Q&A to get my phone to work with Ubuntu: 
How to connect Nokia Lumia 520 to Ubuntu 12.04 
Unfortunately the installation failed for me.  When updating I get the following error:
W: Failed to fetch http://ppa.launchpad.net/langdalepl/gvfs-mtp/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/langdalepl/gvfs-mtp/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

E: Some index files failed to download.  They have been ignored, or old ones used instead. 

How can I get this PPA to work?  Is there any other method to access the files and folders on my phone? 

A:

"13.10 (Saucy) and newer versions of Ubuntu contain all of these changes, so you don't need to use this ppa any more. 
 More info: https://launchpad.net/~langdalepl/+archive/ubuntu/gvfs-mtp"
Run these commands in an open terminal to fix the problem. 
sudo rm langdalepl-gvfs-mtp-trusty.list
sudo apt-get update

Plug the phone in and reboot.  This method also works to mount USB connected devices as well as SD cards.
