    After Upgrade to v16.04 - Install Software Disappeared?

    On two machines, upgraded to UbuntuStudio v16.04 and Xubuntu v16.04 and Software Center disappeared. Since the Upgrade REMOVED Office and other Apps such as PulseAudio, How do we get back ability to INSTALL Software?

    Thanks!

    Found this - "Ubuntu Software Centre has been replaced by Gnome Software (re-branded Ubuntu software) and its software catalogue is still under construction. And we do need the partner repositories enabled."
    Here; https://ubuntuforums.org/showthread....ware+installer

    But we don't have this either.

    Package software-center is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or

    Well the only thing I can offer right now is
    Do not forget about synaptic.
    Code:
    sudo apt install synaptic gdebi
    I was under the impression that the package manager was fixed..but I guess not.

    I am sure you have updated...lets see what your repo list is like
    Code:
    mousepad /etc/apt/sources.list
    Or use the native text editor

    Also changed in Repository from "trusty" to "xenial", but it did not fully work. See above output in Post #4.

    Have a look at the Software and Updates application, and check that the relevant repositories are selected.
