When you tested the two ppa were you "uninstalling" something before installing the second one? Or, can you just download and install over the top? When there are apt-get package managers involved are there other special considerations for "doing this right"?
You do not need to uninstall old drivers.PPA just adds an extra repository to /etc/apt/source.list. To achieve this run
- Code: Select all
sudo add-apt-repository ppa: launchpad_user_name/repo_name e.g: oibaf/graphics-drivers
sudo apt-get update
If an older versions of the software is already installed (e.g. graphic-drivers), just run
- Code: Select all
apt-get dist-upgrade
in case of new software (e.g. makehuman) run
- Code: Select all
apt-get install makehuman
In case of graphics drivers you need to restart at least the X-server, log out or better reboot. General hint: every ppa shows the information you need to install it.
to remove a ppa use ppa-purge (needs to be installed first!)
- Code: Select all
ppa-purge ppa:launchpad_user_name/repo_name
then apt-get uninstall --purge packagename or in case you want to downgrade (e.g. drivers) apt-get update + dist-upgrade
How would I go about rolling back to the Ubuntu 16.04 upgrade that existed when I first upgraded from 14.04, because I'm thinking MH was rendering fine until a "mesa upgrade". If you know Docs worthy of reading I'm game to check them out!
I don't now a way back. You can use a live media to test. It is also possible to install software in live mode. Get a 16.04 iso, since 16.04.1 is already an updated version from July. I have recently checked a 16.04 Kubuntu, too, with the same result (hint: I wasn't able to resolve and install all dependencies for MakeHuman on Ubuntu so I had to switch to Kubuntu, probably the problem was on my testing setup). Here is a US-server
