Installing Veyon on Raspian Failed



  • https://veyon.nodebb.com/topic/841/installing-veyon-on-rpi-with-raspian

    I followed this guide here.

    Getting the following error.

    sudo add-apt-repository ppa:veyon/stable
    Traceback (most recent call last):
    File "/usr/bin/add-apt-repository", line 95, in <module>
    sp = SoftwareProperties(options=options)

  • On raspian, you should add the PPA to your APT configuration (sources.list). For stretch you should add

    deb http://ppa.launchpad.net/veyon/stable/ubuntu xenial main
