Login screen does not open on Ubuntu 14.04

[Luke_M_1]

Hello,

Problem
I cannot get to the login page after I open Intel XDK. There is a loading wheel that just spins forever until an error message comesup  with the error 'Attempt to contact authentication server is taking a long time. You can wait, or check your network connection and try again.'. My network connection is not modified in anyway, literally just a computer connected to a switch which is connected to a fibre-optic router. There are no proxy settings in the way.

What I did from the beginning until I noticed the problem
I noticed an issue when I attempted to download the application from https://software.intel.com/en-us/intel-xdk on my Ubuntu machine. The download just stalled at 'initialising' until an error message popped up (which I have since forgotten but was something to the effect of it is taking too long to start the download). I went to a windows computer and the download worked as expected. I then copied the install file onto a USB and installed it on my Ubuntu machine. After installing, I clicked 'Sign up' on the in-app prompt. This opened as expected and I was able to create an account. However, after the dialogue closed, the translucent black overlay remained and I was unable to do anything on the application. There were no loading indicators. I restarted XDK and attempted to login (this was when I noticed the problem). To make sure that the sign up process actually went okay, I attempted to login using a browser. I got a certificate error for sfederation.intel.com (server's certificate violates name constraints). After proceeding by clicking continue in the more info section, I was able to login. 

System Config
Ubuntu 14.04 (64-bit)
Chrome 46.0.2490.86 (64-bit)

Here is a log of a startup incase it is useful:

Hi Luke, there is some maintenance work going on for Enterprise login servers which could have affected your login, I'll check with that team to see what's going on. Meanwhile could you try few things and let me know:

1) You mentioned you were not able to download the XDK on your Ubuntu machine. Are you able to download now without any trouble?

2) The login problem could be temporary, try again and see if it works. Try to login at signin.intel.com using your credentials (from Ubuntu as well as Windows machine) and let me know if that works and what's the difference.

3) Please double check your network setting, make sure you have no system wide proxy set.

4) If you are able to login at signin.intel.com then uninstall the XDK completely and re-install 

[Luke_M_1]

Thank you for your response.

I attempted to download XDK from my Ubuntu machine and was unable to do so

I have to click on trust certificate If I am to login to the intel site

My Network settings are definitely at their default setting

I have just reinstalled XDK to no avail

Hi Luke,

Please run this command and send me the output.

openssl s_client -showcerts -connect sfederation.intel.com:443 

To come out of openssl press Ctr-C.

Note
Before I opened this support ticket, I thought that (because Chrome was complaining about certificates and refusing connections) there may have been a system wide certificate issue and the XDK was failing silently because of that. I attempted to install a system wide certificate allowing sfederation.intel.com, but that did not help, so I uninstalled it. Also, I have told Chrome to allow sfederation.intel.com

Hello Luke,

Could you check one more thing? Please load the site https://sfederation.intel.com/ in chrome browser, click on the  lock icon or page icon. Under the connections tab there is "Certificate Information" link. Please click on that and send me the screenshot.

Note, the invalid certificate being spoken of is the one created when you click 'Proceed to website.com' in Google Chrome

Hi Luke,

Can you run this command and let me know the output?

sudo dpkg -s libnss3 | grep Version

There was a libnss bug that could cause this issue. If your version isn’t 2:3.17-0ubuntu0.14.04.1 or later then run “sudo apt-get update ; sudo apt-get upgrade” command to upgrade the necessary packages.

Hello, I was running an old version of libnss3. Running the apt-get command did not update my version (Anyone reading this in the future, do not manually install the latest version of libnss3, as I did. You'll find you no longer have internet when package dependencies fail!). I did however install Ubuntu 15.10, and I am now able to login. I can't however open my project (created on OS X El Capitan)
