I was checking put and get command for subsequent versions of vsftpd. For every version it's giving the same error even for vsftpd_v1. Please help

check out for permissions .
you dont have desired permissions

Use this as a reference

@snehil7497 also, check your current lcd.
change your lcd by :
lcd /home/crio-user/ftp_client

Give permissions to all versions of vsftpd.

Change the permission of the directory in which you are uploading the file. You don’t have the permission to write on that directory.
