CyberPanel Project Bug Report

Hello.
I got this error at the end of the upgarde. Should we worry about this?

Hi,

You must have a process using the virtualenv already so the copy of the python executable is ‘in use’ (technically it’s mmap()'ed into memory whilst it’s executing).

The solution is to kill that process.
To check if service is running use this command
ps -ef | grep python

Use “ps a” to get the PID of your process then kill that process using "kill -9 " command where is the process id.

Then start with the upgrade process again and you shall not face this issue again :slight_smile:
