Hi mrbmcg,
Why on earth would you move from a stable 14.04 to this crap? :-(
That canonical Ubuntu moved the LTS support from 14.04 → 16.04 - notice the “LTS” on: “Ubuntu 16.04.1 LTS (Xenial Xerus)” per: http://releases.ubuntu.com/16.04/
You can find particular libraries by using the “apt-file search XYZ.so” command to see which debian package you need to install and if it exists on this 16.04 version of Ubuntu (sometimes the packages are just “re-named” from previous ubuntu versions like 14.04). You could also troll through the ubuntu web-ui for packages (obviously for xenial instead of trusty):
http://packages.ubuntu.com/trusty/glade-gtk2
or check on Launchpad etc to see if the package was renamed or grab the sources:
https://launchpad.net/ubuntu/xenial/+source/glade
And if it isn’t available on 16.04 (this is a ubuntu thing not an NVIDIA issue) you can either download a previous version and install it, or you can download the sources and build from it. But in no cases is this a bug from NVIDIA SW.
Hope this helps.
Thanks
