Hello,

I am currently trying to install Hail on a VM running Ubuntu, and I’m running into some problems.

I successfully installed everything in the Linux installation tutorial except libopenblas (All it says is that it is unable to locate it), but I instead downloaded libblas3 (I have literally no idea what BLAS is, so I’m just using guesswork here; the problem might be in this step tbh).

Then, I went on to use pip3 to install hail, and this is what happened:

```
csf@csf-vm:~$ sudo pip3 install --no-cache-dir hail

```

So, it seems like pip is receiving a different hash than is needed and, for security reasons, doesn’t let Hail download. Can someone help me through this?

Hey @vrizzari,

I’m sorry about the libopenblas package, there is a bug in our install documentation. You need to install `libopenblas-base`.

This error usually means you have a bad cache, though you’re using `--no-cache-dir`. It could also mean someone is manipulating your internet connection. I’m able to install the hail package on a fresh copy of Ubuntu:18.04. The first thing I think you should try is upgrading pip: `pip3 install -U pip`.

Hey @vrizzari,

Did you happen to resolve this issue? I’d be curious to know the outcome.

Can you also share more detail on your set up? I think there must be something unusual happening. A few questions to get started:

- What kind of VM software are you using: Docker, VirtualBox, a cloud VM, something else?
- Laptop or a remote machine?
- What is the host operating system: Windows, Linux, or Mac?
- How is this machine connected to the internet: wifi or wired? And is it a corporate, academic, cloud, or home network?
- Are you able to install other packages? For example, `pip install aiohttp`, does that give any error?
- How did you install python3: `apt-get`, `pyenv`, or `conda`?
- Are you using `virtualenv` / `venv`?
