How to generate new Ubuntu ISO image using PinguyBuilder

Make sure all the necessary tools and packages mentioned in the list are installed.

Go to Applications→PinguyBuilder.

Unmount all the share drives in your environment using the Linux command 'umount <drive_path>'.
Go to Settings and update the ISO filename and the working directory for ISO generation. Nevertheless, you can rename the ISO after it is created too.

Go to Actions and choose 'Dist' option to make a distributable iso.

Click 'OK' to start ISO generation process. The process will take a while. Initially it will cleanup the temporary files and any unwanted libraries. Then it starts copying the filesystem.

Incase you want to add or delete any libraries during this process, you can edit the PinguyBuilder script located at /usr/bin/PinguyBuilder

Pinguy Builder version 4.3.8 seems to remove g++ packages when creating ISO so make sure to comment out below line in the Pinguy Script located at /usr/bin/PinguyBuilder if you want to include this package in the custom ISO

dpkg -l 'linux-' | sed '/^ii/!d;/'"$(uname -r | sed "s/(.)-([^0-9]+)/\1/")"'/d;s/^[^ ] [^ ] ([^ ])./\1/;/[0-9]/!d' | xargs apt-get -y purge

The generated ISO file is placed in working directory mentioned in Settings. By default, it is placed at /home/PinguyBuilder/PinguyBuilder.
Another way to create the ISO is , choose 'Distcdfs' first. The PinguyBuilder will generate the filesystem for the ISO. Now, you can add files to the filesystem if you want any. Then click 'Distiso' to generate the ISO.
