Problem in setting bolt python library

this error is coming on the very first command in setting bolt python library in vmware i.e. sudo apt-get -y update
kindly help…

Hi @sur.sharma0197,

To resolve this problem from terminal you must remove/comment this CD-ROM repository source directly from /etc/apt/sources.list

sudo nano /etc/apt/sources.list

and comment or remove lines that include cdrom . eg:

deb cdrom:[Ubuntu-Server 16.04 LTS _Xenial Xerus_ - Release amd64 (20160420.3)]/ xenial main restricted

Do let me know in case you need any other information.
