I'm unable to add kakreuger/openstreetmap

I get the following:

sudo add-apt-repository -y ppa:kakrueger/openstreetmap
Cannot add PPA: 'ppa:kakrueger/openstreetmap'.
Please check that the PPA name or format is correct.

look through /etc/apt/sources.list and change "vivid" to "trusty"
/etc/apt/sources.list.d/kakrueger-ubuntu-openstreetmap-vivid.list
