Every time I run a Kivy app I see OSError (see it in last line of my given example). Even though my app runs successfully. What could be the cause of this error?
Exception in thread Thread-1:

This error is not important, it just means that kivy checked the possible input providers in your OS and found that this one is forbidden.

I am attempting to run the bcc tool's "profile.py", and ran into the following error:

The linux headers are found under the normal location of /lib/modules. This is running under kernel version 4.19.88.
Any pointer will be appreciated.
I am trying to get LetsEncrypt SSL certificates installed on a Centos 6 server using Cerbot-Auto, however no matter what I try, it just hangs on:
Apache version is 2.2.15
Command
./certbot-auto -v
When I press CTRL + C to exit the program, it takes about 15 seconds and then exits with a stack trace:

Please see the logfiles in /var/log/letsencrypt for more details.
I thought it may be a python version issue but when checked, the server is running Python 2.6.6, which, according to the Certbot System Requirements is acceptable.
Letsencrypt.log
When I checked the log, it is exactly the same stacktrace as was reported by the script previously.
Any ideas?
I installed python version 3.5.2, selenium version 3.0.1 and firefox version 49.0.2.
After all of that and in my shell scripting I typed
>>> from selenium import webdriver
>>> browser = webdriver.Firefox()
and got error as this below:
Could someone guide me on what is wrong here.
I appreciate it. I am just starting out on python. Thanks

I am using HDP 2.4.2 and I had previously installed the zeppelin server. It was working fine but today when i restarted the cluster ( AWS nodes were restarted), Ambari shows that Zeppelin server is not running and fails to start the server with the following error:

But for some reason, the zeppelin port is listening and despite these errors, the zeppelin server is running fine and executing all the queries. Please advice on how to correct the issue in Ambari and start the service without error from ambari.
The problem is with the PID file for the zeppelin service. It's either owned by the wrong user or has the wrong permissions. Manually stop the zeppelin service then delete the pid file locate at: /var/run/zeppelin-notebook/zeppelin-zeppelin-ip-10-0-0-11.eu-west-1.compute.internal.pid. Double check the owner/permissions on the /var/run/zeppelin-notebook folder as well. You should then be able to restart the service in the Ambari UI.
I'm trying to run bokeh-server with supervisor with redis as a backend and I get this error message on startup:

Note that I can run the server with supervisor if I use memory as the backend, and I can run bokeh-server manually with redis as a backend just fine. Does anyone know where the permissions I should change lie?
Turns out it was trying to access the pidfile in the root directory...
I solved this by changing the directory in the supervisor config file:
[program:bokeh]
...
directory=/usr/share/nginx/test-status
...
