Using Dotdeb is very simple:

1. Add the main repository to your sources.list

Depending on your distribution (Wheezy or Squeeze), add these two lines to your /etc/apt/sources.list file (you can also choose a mirror near you) :

deb wheezy all
deb-src wheezy all


deb squeeze all
deb-src squeeze all

2. Options

If you want to install :

  • PHP 5.6 on Debian 7 “Wheezy”, add these two lines too :
    deb wheezy-php56 all
    deb-src wheezy-php56 all
  • PHP 5.5 on Debian 7 “Wheezy”, add these two lines too :
    deb wheezy-php55 all
    deb-src wheezy-php55 all
  • PHP 5.4 on Debian 6 “Squeeze”, add these two lines too :
    deb squeeze-php54 all
    deb-src squeeze-php54 all

3. Fetch and install the GnuPG key

sudo apt-key add dotdeb.gpg

4. Enjoy

Run apt-get update. You should now be able to install the Dotdeb packages you want with apt-get (or dselect, or aptitude as well…)
