Basic Tethys Installation Problems

[Norm Jones]

Hey folks. I had to reinstall Ubuntu so I am now re-installing Tethys. Getting some errors so I am curious if any of you have any suggestions or recommendations.

First of all, I got an error message on Step 1. 

E: Failed to fetch http://us.archive.ubuntu.com/ubuntu/pool/main/p/python-defaults/python-all-dev_2.7.11-1_amd64.deb  400  Bad Request [IP: 91.189.91.23 80]

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I redid the install command with "--fix-missing" and didn't give any error messages that time, so I am hoping that issue is resolved.

Second, I got and error message on Step 2. I issued this command:

$ source /etc/bash_completion.d/docker

And it said there was no such file. I pathed down into the directory and there is nothing there docker related. I reinstalled the docker.io package and didn't get any error messages. Is this just an outdated command or something?

More problems. Did the docker initialization. Then I tried to start the dockers. Got the following error messages. Related to earlier problem? Dead in the water at this point.

(tethys) njones@ubuvm:~$ tethys docker start

Looks like Christian had the same problem:

I have installed Ubuntu 16.04. I will downgrade to 14.04 and try again.

Sorry for the late response on this. As you have pointed out, the confusion is occurring because the current release of Ubuntu is 16.04 and the main download button will give you this version. You need to use the Alternative Downloads page to get version 14.04. I will point out that 14.04 is still in long term support status (LTS) meaning they will continue to issue security updates making it safe to use for web. I have added a warning to the documentation that provides a link to the Alternative Downloads page.

FYI. I have posted installation instructions for Ubuntu 16.04 on the development documentation. These instructions will only work for the dev branch (1.4) because of issues with the newer version of Docker. These issues have been resolved in dev, but will cause you grief with 1.3.0 or lower.

Note: I've also added Alan's tip of setting an alias for activating the virtual environment to both sets of installation docs.
