问题
I want to open spyder(Python IDE) in ubuntu.
Normally I would write "spyder" in the shell, and it would open the spyder IDE.
Now when I write spyder in the shell, it just new lines, and nothing happens(similar to pressing 'enter').
--- How do I get my spyder back?
EDIT - I get no errors, it just skips to the next line.

If typing "spyder" doesn't work, you might want to try typing "spyder3" in case you installed the spyder3 version. Below is what worked for me in my Ubuntu system.
To install spyder via pip (my python version is 3.6.2), I used:
pip install spyder
Then, I had to install another package:
pip install PyQtWebEngine
Finally, to open the Spyder window, I typed into my terminal:
spyder3

You may simply have to update spyder.
If you are NOT using anaconda:
pip install --update spyder
Or, if you are in anaconda:
conda update spyder
I had the same issue as yours, with also a message in the command line saying:
Spyder is already running. If you want to open a new
instance, please pass to it the --new-instance option
The above update allowed me to open spyder from the command line.

I had this problem as well, and found this post on it in an askubuntu forum. It suggested using sudo apt-get purge spyder to delete any faulty configuration files and then reinstall with sudo apt-get install spyder. I found it worked, and spyder reopened with my previous files on the text editor.
