PeterJ's questions

I have installed a fresh copy of Ubuntu 18.04 on my PC with an AMD HD7900 Graphics Card. I believe the code name is 'Tahiti'

First thing I did was install the Oibaf PPA

https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

Then I did a sudo apt-get update && sudo apt-get upgrade && sudo apt install mesa-vulkan-drivers

When I type vulkaninfo, I get the following message.

VULKAN INFO
===========

Vulkan Instance Version: 1.1.70

/build/vulkan-Kbdbga/vulkan-1.1.70+dfsg1/demos/vulkaninfo.c:2700: failed with VK_ERROR_INITIALIZATION_FAILED

I find the Vulkan guidance very confusing so would appreciate any help. I'm hoping to play the new Tomb Raider game.

Thanks

I'm trying to do an installation of OpenStack DevStack on a clean installation of Ubuntu 16.04 Desktop.

The Setup stops when it comes to the following error:

+inc/python:pip_install:359                env http_proxy= https_proxy= no_proxy= PIP_FIND_LINKS= SETUPTOOLS_SYS_PATH_TECHNIQUE=rewrite /opt/stack/requirements/.venv/bin/pip install -c /opt/stack/requirements/upper-constraints.txt -U pbr
env: ‘/opt/stack/requirements/.venv/bin/pip’: No such file or directory

I also see lots of warnings about Python versions:

Requirement already satisfied: systemd-python===234 in /usr/local/lib/python2.7/dist-packages (from -c /opt/stack/requirements/upper-constraints.txt (line 401))
You are using pip version 9.0.3, however version 10.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm running Python 2.7.12 and 3.5.1-3

I setup the user with sudo useradd -d /bin/bash -d /opt/stack -m stack

Thanks
