Spyder fails to start on light mode because of check_updates code

[stonebig]

when launching spyder_light on Python3.4/PyQt5.5.0/Jupyter4/spyder-3.0.0dev, i get this strange error:

Traceback (most recent call last):
  File "python-3.4.3.amd64\lib\site-packages\spyderlib\spyder.py", line 3103, in main
    mainwindow = run_spyder(app, options, args)
  File "python-3.4.3.amd64\lib\site-packages\spyderlib\spyder.py", line 2999, in run_spyder
    main.post_visible_setup()
  File "python-3.4.3.amd64\lib\site-packages\spyderlib\spyder.py", line 1308, in post_visible_setup
    self.check_updates()
  File "python-3.4.3.amd64\lib\site-packages\spyderlib\spyder.py", line 2900, in check_updates
    self.check_updates_action.setDisabled(True)
AttributeError: 'NoneType' object has no attribute 'setDisabled'

on a side-note, I would be happy if the check_update was disabled per default

the problem goes away if I un-clicked the "check for updates" via a Spyder normal session

@goanpeca, please take a look at this one. It should be an easy fix :-)

[goanpeca]

Will do!

@stonebig I understand, but the idea of the check for updates is to drive the community into the newest version possible, we receive a lot of questions from people still in 2.2.x ....

Disabling it by default really does not help in this direction.

@spyder-ide/core-developers?

[ccordoba12]

I agree with @goanpeca, but I also understand @stonebig, given that he is a packager. Let's leave for another issue though.

[goanpeca]

ok

[stonebig]

can you confirm me the line of code that decides the default initial behavior is in main.py the check_updates_on_startup = True ? ok, it is.

I'll change the default initial behaviour to 'False' for my sub-case, as I think it's important.

[goanpeca]

Should be this one
