Create Ubuntu Live DVD using Pinguy Builder

Remastersys was one of the best tool for live DVD creation. Remastersys project seized and not available now. Now Pinguy Builder available for this purpose. Pinguy Builder developed from Remastersys source code. So Pinguy Builder is very easy to use tool for live dvd creation.

I tried to build Live DVD from Ubuntu MATE Linux. MATE Desktop available with this Ubuntu distro. MATE desktop gives classic look, not like Unity.

1. Download and install Ubuntu MATE version either 14.04 or 16.04.

2. Download Pinguy Builder package. Choose appropriate version. Read the instructions in the download page first. Pinguy Builder Version 4 works with Ubuntu 16.04 and select version 3 for Ubuntu 14.04.

3. Install Pinguy Builder.

Open terminal and install the package.

sudo su

dpkg -i pinguybuilder*

The package required dependancy files. The command execution will end with error messages. Try to install dependency files,

apt-get install -f

Pinguy Builder can find in System > Administration after installation.

4. Prepare system for Live DVD creation (Add and remove applications).

5. Build Live DVD using backup/Dist option.

Duct Tape Flowers

Duct Tape flowers are an easy craft that only require a pair of scissors, at least one roll of duct tape, and a pencil to start with. I sincerely recommend you do this as I spent 4 and ½ hours with my friends making these, my friends learned how to make them in about 5 minutes, and then we made them for the rest of our sleepover. We found them very, very addicting to make. We also found that after a hour or so, the motions become automatic. You should try this if you want a easy, fun craft to do!
