Error with examplePlugin

wordpressuser

cd /usr/local/CyberCP/pluginInstaller && \
python pluginInstaller.py remove --pluginName examplePlugin && \
python pluginInstaller.py install --pluginName examplePlugin

I tried to run this command 6 times and get an error:

and

Also I want to ask is there a way to remove url and view because it's just a background application after deleting the database (or another action).

Fix menu:

Line 81, add: + "\n"
/cyberpanel-stable/pluginInstaller/pluginInstaller.py

writeToFile.writelines('{% trans "' + pluginName + '" %}' + "\n")

And
Line 897, write all li tag in one line
/cyberpanel-stable/baseTemplate/templates/baseTemplate/index.html

    
        {% trans "Installed" %}
    

p/s:
How can I get POST variable from request (ex: preSubmitDBCreation) in file signals.py?
