I'm getting this error
"E: Package 'whosthere' has no installation candidate" "E: Unable to locate package telepathy-whosthere"
any ideas how to fix this please ?
Edit the file with your favorite text editor (with root) :
gksudo gedit /etc/apt/sources.list.d/m-gehre-ppa-raring.list
Change "raring" to "quantal" as following :
deb http://ppa.launchpad.net/m-gehre/ppa/ubuntu quantal main
Then install whosthere
sudo apt-get update sudo apt-get install whosthere
Please note that the package development is discontinued.
Looks like it's not in your repositories.
Try to refresh (apt-get update), then, if still no success, add a new repo, which does contain this package.
