I had installed KDE Connect on Ubuntu 16.04, but for some reasons I wanted to reinstall it.
So I purged the packages I had and now I'm unable to install it either via Software Center or via CLI.
I've tried http://www.omgubuntu.co.uk/2017/01/kde-connect-indicator-ubuntu and How to install KDE connect in ubuntu 17.04?, but they don't seem to work and I always get these errors:
Err:1 http://ppa.launchpad.net/varlesh-l/indicator-kdeconnect/ubuntu xenial/main amd64 kdeconnect amd64 1.0.3ubuntu16.04
