# OK, here's how to do the Apt magic to get PHP packages from the karmic repositories:

echo "Am I root?  "
if [ "$(whoami &2>/dev/null)" != "root" ] && [ "$(id -un &2>/dev/null)" != "root" ] ; then
  echo "  NO!

Error: You must be root to run this script.
Enter
sudo su
"
  exit 1
fi
echo "  OK";


#install aptitude before, if you don`t have it:
apt-get install aptitude
# or if you prefer apt-get use:
# alias aptitude='apt-get'

# finish all apt-problems:
aptitude update
aptitude -f install
#apt-get -f install

# remove all your existing PHP packages. You can list them with dpkg -l| grep php
PHPLIST=$(for i in $(dpkg -l | grep php|awk '{ print $2 }' ); do echo $i; done)
echo these pachets will be removed: $PHPLIST 
# you need not to purge, if you have upgraded from karmic:
aptitude remove $PHPLIST
# on a fresh install, you need purge:
# aptitude remove --purge $PHPLIST


#Create a file each in /etc/apt/preferences.d like this (call it for example /etc/apt/preferences.d/php5_2);
#
#Package: php5
#Pin: release a=karmic
#Pin-Priority: 991
#
#The big problem is that wildcards don't work, so you will need one such stanza for each PHP package you want to pull from karmic:

echo ''>/etc/apt/preferences.d/php5_2
for i in $PHPLIST ; do echo "Package: $i
Pin: release a=karmic
Pin-Priority: 991
">>/etc/apt/preferences.d/php5_2; done

# duplicate your existing sources.list replacing lucid with karmic and save it in sources.list.d:
#sed s/lucid/karmic/g /etc/apt/sources.list | sudo tee /etc/apt/sources.list.d/karmic.list

# better exactly only the needed sources, cause otherwise you can get a cachsize problem:
echo "# needed sources vor php5.2:

aptitude update

apache2ctl restart

echo install new from karmic:
aptitude -t karmic install $PHPLIST

aptitude -t karmic install libapache2-mod-php5

apache2ctl restart

Debian

Op debian kun je ook de ubuntu packages gebruiken. Dit staat hier omschreven:

Remove the PHP 5.3 packages from your system:
sudo aptitude purge `dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`
Clean the cache just to be sure:
rm -f /var/cache/apt/archives/php5*
Use Karmiс for PHP packages:
echo -e "Package: php5\nPin: release v=karmic\nPin-Priority: 991\n" | sudo tee /etc/apt/preferences.d/php > /dev/null
apt-cache search php5-|grep php5-|awk '{print "Package:", $1,"\nPin: release v=karmic\nPin-Priority: 991\n"}'|sudo tee /etc/apt/preferences.d/php > /dev/null
Add Ubuntu Karmic to source list:
cd /etc/apt/sources.list.d
sudo wget -O karmic.list "http://pastebin.com/download.php?i=wrgw4kTc"
Update the package database:
sudo apt-get update
If the command above produces this error:
W: GPG error: http://security.ubuntu.com karmic-security Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5
W: GPG error: http://archive.ubuntu.com karmic Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5
W: GPG error: http://archive.ubuntu.com karmic-updates Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5
Then import the required keys and add them to your list of trusted keys:
gpg --keyserver hkp://subkeys.pgp.net --recv-keys 40976EAF437D05B5
gpg --export --armor 437D05B5 | sudo apt-key add -

gpg --keyserver hkp://subkeys.pgp.net --recv-keys 40976EAF437D05B5
gpg --export --armor 40976EAF437D05B5 | sudo apt-key add -

gpg --keyserver hkp://subkeys.pgp.net --recv-keys 40976EAF437D05B5
gpg --export --armor 40976EAF437D05B5 | sudo apt-key add -
Finally, install PHP 5.2:
sudo apt-get install -t karmic php5-cli php5-cgi libapache2-mod-php5
UPDATE: Using the Ubuntu sources to download old packages works on Debian. So far, it works on my system, but you may need to use the Debian sources just in case.
