Spyder fails to launch because of errors in spyder.ini

Description of your problem

What steps will reproduce the problem?

My spyder was working fine, I did an update on my linux and now it does not run at all. I installed it again and it does not run yet.

What is the expected output? What do you see instead?
I get this traceback:

Versions and main components

• Python Version: 3.5
• Operating system:Linux 15.10

Try spyder --reset. You'll lose your spyder config but it should fix your problem.

Gives me same error:

Actually, I installed anaconda again and still getting the same error! iPython works though!

Then please do

rm -Rf ~/.spyder2-py3

and try again

@ccordoba12 I have a similar problem. When I run spyder in command line, I got this message.

My Error is UnicodeDecodeError related to 'ascii'. I tried your suggestion.
But I can not fix it.
Could you tell me how to fix it, if you have another solution?

@eunsoo, your problem is different. Please open a new issue about it and include the output of running

printenv

in a terminal (i.e. in bash or zsh :-)
