I have fresh install Ubuntu 14.04 with all the coding stack that I need. I would like to create and image of this installation for duplicate it in the other computers without the same effort. Is there any way to do that ?

  • What kind of disc image? Full raw copy, which backs up absolutely everything there is? Or file copy? (in the second case you might wait)

You can use fsarchiver, Clonezilla, dd or ddrescue, partimage, remastersys, G4L (Ghost for Linux), ...

Please do some research into these tools and if you get stuck, open a new question.

If you just want to install the same packages on other machines:

Step 1: Store the list of installed packages

Run the following command on the source machine to store the installed packages names in ~/pkglist:

sudo dpkg --get-selections | sed "s/.*deinstall//" | sed "s/install$//g" > ~/pkglist

Step 2: Transfer your config

Use scp or rsync or even a flash drive to transfer your home directory (~/*, ~/.*), the source list (/etc/apt/sources.list) and any other files you customized or installed (like apache config under /etc or software on /opt) from the source machine to the target one.

Step 3: Install packages

On the target machine run the following command in a failsafe terminal session to install your packages:

sudo aptitude update && cat pkglist | xargs sudo aptitude install -y
