I want to use TensorFlow on Ubuntu 16.04, which requires CUDA 9.0, not the latest 9.1. However, I previously had CUDA 9.1 installed. After running
sudo apt-get remove --purge cuda* && sudo apt-get autoremove
I confirmed that /usr/local contained no cuda folders. Then,
I followed the nvidia instructions to install CUDA 9.0 using the .deb. However, when I sudo apt-get install cuda, the confirmation message begins with:
The following NEW packages will be installed:
cuda cuda-9-1 ...
and other references to CUDA 9.1.
Question: Why is this 9.1 version being installed? Where is this being linked from?
Here is the output from apt-key list, if helpful:

sudo apt-get install cuda-9.0. However, your suggestions do not answer my question: how do I find which repository is trying to install the unwanted package?
