Module 3 milestone 1. Can't change conf file

Failed to save ‘vsftpd_v1.conf’: Unable to write file (NoPermissions (FileSystemError): Error: EACCES: permission denied, open ‘/home/crio-user/workspace/QBox/vsftpd_v1.conf’)

I am getting this error. chmod +rwx isn’t working to give permission to the file. Can anybody help?

try changing the ownership of the file

You can use a terminal editor to open the file and change it.
