    Wink DownGrading php 5.3 to php 5.2

    Ok guys!

    I made this thread for solving out previous cases, for all common ubuntu users who have already installed their php 5.3.

    I assume that you all in these condition:

    1) Your Repository is still default
    2) You have LAMP already installed
    3) You have Internet Access
    4) You have root privileges




    OK. Let's start!

    1) Ensuring that you do have php 5.3.x installed
    How to check that we have php installed?
    simple. Execute this command;

    Code:
    $> dpkg -l | grep php
    You'll get the output pretty similar with this;

    ii libapache2-mod-php5 5.3.2-1ubuntu4.2 server-side, HTML-embedded scripting languag
    ii php5-common 5.3.2-1ubuntu4.2 Common files for packages built from the php
    ii php5-curl 5.3.2-1ubuntu4.2 CURL module for php5
    ii php5-gd 5.3.2-1ubuntu4.2 GD module for php5
    ii php5-imap 5.3.2-0ubuntu2 IMAP module for php5
    ii php5-mysql 5.3.2-1ubuntu4.2 MySQL module for php5
    OK. Now it means you are in a OK' condition. Continuing next step.

    2) Downgrading Php 5.3 to 5.2

    Once you're already sure that you do have php 5.3 installed. Then now,
    What you will do now is copy and paste this source code below
    save it within a file named downGradeNRemove.sh
    Just save it anywhere you wanted.

    Code:
    php_installed=`dpkg -l | grep php| awk '{print $2}' |tr "\n" " "`
    
    # remove all php packge
    sudo aptitude purge $php_installed
    
    # use karmic for php pakage
    # pin-params:  a (archive), c (components), v (version), o (origin) and l (label).
    echo -e "Package: php5\nPin: release a=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 a=karmic\nPin-Priority: 991\n"}'|sudo tee -a /etc/apt/preferences.d/php > /dev/null
    apt-cache search -n libapache2-mod-php5 |awk '{print "Package:", $1,"\nPin: release a=karmic\nPin-Priority: 991\n"}'| sudo tee -a /etc/apt/preferences.d/php > /dev/null
    echo -e "Package: php-pear\nPin: release a=karmic\nPin-Priority: 991\n"  | sudo tee -a /etc/apt/preferences.d/php > /dev/null
    
    # add karmic to source list
    egrep '(main restricted|universe|multiverse)' /etc/apt/sources.list|grep -v "#"| sed s/lucid/karmic/g | sudo tee /etc/apt/sources.list.d/karmic.list > /dev/null
    
    # update package database (use apt-get if aptitude crash)
    sudo apt-get update
    
    # install php
    sudo apt-get install $php_installed
    # or sudo aptitude install -t karmic php5-cli php5-cgi //for fcgi
    # or  sudo apt-get install -t karmic  libapache2-mod-php5 //for apache module
    
    sudo aptitude hold `dpkg -l | grep php5| awk '{print $2}' |tr "\n" " "`
    #done
    And now, please use Sudo or any root privilege enabled, and execute this file.
    How to execute this file anyway?
    Pretty funny.
    To execute the file, You just need to change the mode of this file to be executable.
    Here is the command;

    Code:
    $> chmod u+rx downGradeNRemove.sh
    Then, execute it!
    Code:
    $> ./downGradeNRemove.sh
    Ok!
    Now, let's ensuring that you do now have php 5.2,
    execute the previous command;

    Code:
    $> dpkg -l | grep php
    You'll obviously got output saying the php. 5.2. I'm sure.

    Ok! done!
    Now just restart your apache2 by executing this command

    Code:
    $> /etc/init.d/apache2 restart

    Boing! Done.

    If you ask me which resource I got?

    From russian article;
    From english article;

    Re: DownGrading php 5.3 to php 5.2

    Thanks for scripting the creation of aptitude settings for a PHP5 package downgrade.

    I made a change to the first line in your script so that it doesn't include packages like "phpmyadmin" or "webmin-phpini" that I have installed. Here's the ammended first line:

    Code:
    php_installed=`dpkg -l | grep php5 | awk '{print $2}' |tr "\n" " "`

    This also works for Maverick if you edit the script and replace,

    lucid -> maverick

    Just had to do a downgrade on a system and this script made it easy.

    Thanks!

    Re: DownGrading php 5.3 to php 5.2

    Some additional notes on the process:

    *Note: apt-cache will display currently installed packages AS WELL AS the packages available in the repository. If a package won't go away, it's probably installed locally.

    o Double-check that new installations default to installing from the original repository. We're not sure of the order in which the various repositories are checked. If the order is not correct, try putting both .list files in the same directory, along with a numbered prefix.

    o To install a package from a specific repository, run apt-get or synaptic with the "-t" parameter along with the release's token that was set in the repository above. If a dependency is already installed but from the wrong repository, APT/DPKG will differentiate and fail. All dependencies that will be installed alongside the desired package will come from the same repository.

    o If the older dependencies are in place and you move to install a package that has both old and new versions without specifying a repository, the old dependencies will be officially replaced (using Apt's atomic replace feature) with the new versions.

    Question Re: DownGrading php 5.3 to php 5.2

    This no longer works as the Karmic archives no longer exist at archive.ubuntu.com

    Does anyone have an idea or suggestion to get this downgrade to PHP 5.2.x working?
