Recently I have install the PHP, Apache, MySQL, phpMyAdmin, python in my Ubuntu Desktop 12.04.3 LTS to use it as a LAMP server. The commands I used to install these are given below:

1: sudo passwd

2: su

3: apt-get install php5

4: apt-get install apache2

5: apt-get install mysql-server mysql-client

6: apt-get install phpmyadmin

7: apt-get install python

8: apt-get install python-mysqldb

9: ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf.d/phpmyadmin.conf

10: /etc/init.d/apache2 restart

Then everything works fine. The LAMP server runs great. Then i thought to upgrade the whole LAMP server I mean the PHP, Apahce, MySQL, phpMyAdmin etc. Then I searched in google and get some ppa which got the latest versions of these softwares. Then I added those ppa. The ppa links:

1. https://launchpad.net/~tuxpoldo/+archive/phpmyadmin

2. https://launchpad.net/~ondrej/+archive/mysql-5.6

3. https://launchpad.net/~ondrej/+archive/apache2

4. https://launchpad.net/~ondrej/+archive/php5

Then is used these ppa and firstly upgraded the phpmyadmin then MySQL server then Apache and then PHP.
After upgradation of phpmyadmin and mysql server the whole LAMP server runs well with the updated mysql server and phpmyadmin. But after the upgradation of Apache and PHP the phpmyadmin is not showing up. When I try:

http://127.0.0.1/phpmyadmin

it says "Not Found".

How can I sove this problem with the phpmyadmin?? Please help me as fast as you can. I am in great trouble for this.

Thanks in advance.
