Because I tried to install Python 2.7.10, my entire python is completely f**ed. Thus I am not able to run the other commands. I wrote a question on the issue on http:https://askubuntu.com/questions/648424/moun-is-gone-after-change-of-python-issues-after-python-2-7-10-installation-on but it seems nobody really cares :.-( (or knows anything). |

Ok, the reporting is fine by me. Thank you very much! I am happy to learn this, since it seems to me, this is something worth knowing (how dpkg and and linux internals work and how to fix them if they don't). Since it is already the second time this year that I broke my system because of coursera-dl (last time I reinstalled) I am not so keen of reinstalling again. ;-) Since the notebook in question is my private machine and my business notebook is unaffected, I can "get my work done" without interference. Also, I downloaded the coursera courses the docker-way - so that worked. As soon as I am at my private machine I will try out the other ssl command. I have skype and jitsi. I am waiting for your list of commands I have to use to provide you with information at askubuntu, right? Btw.: I wrote an email to [email protected] |

I'm having this same issue (also Ubuntu 14.04). Once Python 3.4 is installed, but not set as default, how would you run coursera-dl? The default is still Python 2.7.6, but I don't want to change that in order to avoid breaking the entire system (as highlighted above). |
|
@rbrito I haven't gotten any answer/questions from you... |
|
You may find the discussion in issue #330 useful. The underlying problem is Ubuntu 14.04 includes Python 2.7.6, which has some SSL compatibility problems. The simple Ubuntu-friendly option is to install python3 and pip3 via Ubuntu's apt package manager, then do |

@NelsonMinar Thanks for your comment. However, this will not do anymore. Not regarding the state of my System. Its python is completely damaged. See http:https://unix.stackexchange.com/questions/218911/help-me-repair-my-python-i-think-dpkg-has-to-be-reset-very-tricky-issue Edit: It got solved! I might try your solution later. |

@Make42 Python 2.7 pip didn't work for me in both Mac and Ubuntu systems. The following steps worked for me: Mac OSX (Yosemite): Ubuntu 14.04 LTS Usage Example Hope it helps. |

@rbrito You are too late to save my machine ;-). I was able to get the issue solved (see the edit above). Also (I just tried it out) works for me indeed. Maybe this could be put into the README.md... ?! I forked the repo added the changed and made a pull request (it's my first time on github - I thought it might be something small to try this out in the wild.) |

Hi. I'm putting the text that I sent before via e-mail, since github thought that it was just a quote and made an ellipsis out of it. These are some diagnostics that I would appreciate if anybody could run (especially those that experienced the issue, solved/worked-around-it, but still can reproduce it), so that we can better understand the issue. (Oh, improvements to this text are highly welcome; Yes, contributing to our project (especially with documentation) is easy and it's never too late to get started!).

@haisum, first of all, thank you so very much for both your willingness to help and your detailed response. I have other questions (and these are valid for every other poster/subscriber of this bug report---the more answers that we get, the more likely that I am to see the pattern---hopefully): 1 - What is the version of Python 3 that you are using? You can find it via the following command: 2 - Do the problems that you describe persist if you use a virtual environment with your default Python 2 interpreter? 3 - Can you run the tests that I wrote about in #377 (comment) with your Python 2 interpreter outside of any virtual environment? I would really love to know what may be happening and where the issues may lie. 4 - Are you willing to compile a short module for your Python 2 interpreter inside a virtualenv? If yes (and that would help a lot), then I would love it if you, first, installed (regularly, outside of a virtualenv) the following packages in your Ubuntu: Then, create new a virtual environment with Python 2 (as usual), enter it, install everything as you would (e.g., inside the virtual environment type Some of the packages above may be already installed (they were likely installed when you run I have some more questions that I would like to have answered, but let's take those one at a time. :) Thanks a lot, Rogério. |

@rbrito, I installed Ubuntu 14.04 on a virtual machine and followed your instruction about installing new modules: Fortunately, It worked and the error never appeared again. I also test it on windows with Python 2.7.6 already installed and got the same result by only installing |

I was able to solve issue with stock python by upgrading ndg-httpsclient module by using following command: sudo pip install --upgrade ndg-httpsclient This fixes the issue on default python without upgrading it.

Scrub my suggestion above that problem could conceivably be specific to ..."the Data Science Specialization at Coursera. Conceivably course staff rather than coursera doing something new?" I now assume it was just coincidence that my report was from same series of monthly repeated courses as the original report at top of thread. I previously thought it was not occurring for me with several other coursera courses I was still downloading. But they may have been completed with no actual file downloads but just successfully checking the index pages. Just encounted the same problem with unrelated coursera course and it only happens AFTER index page successfully obtained, at first actual file download: Downloading class: valuation-001 PS Have not done and now cannot do any testing due to sudden family emergency. |

Hello, I still get the same errors as a couple of months ago:
I still have Python 2.7.6 on Ubuntu 14.4. I know it would be better to have Python 2.7.10 but this will not change anytime soon, since this is just the Python version that is in Ubuntu 14.4 has. PLEASE, can this be fixed, so that it works with python 2.7.6 ?
(As a matter of fact I even tried installing Python 2.7.10, and even though
