Export list of installed programs and install them on another computer (Ubuntu)

March 23, 2017 - Linux

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 softwares 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 apt-get install aptitude
sudo aptitude update && cat pkglist | xargs sudo aptitude install -y
