Some quick fix for Debian to get all the desired functionalities

I am jotting down the issues that I faced with Debian, in case I or any user requires it for future reference.

1. Change grub: Once Debian installs, it updates the grub and makes it the default distro. In case you have Ubuntu/Mint/Windows installed, you may like to have a different default distro. Steps are

• Record the sequence where your default distro is (starts with 0)
• Go to root terminal and type #gedit /etc/default/grub 
• Change the boot option (default=0) and boot timing (default=5), in case you need it
• Close it after saving
• Come back to root terminal and type #update-grub
• Grub will get updated with your preferred booting option

2. Software center would ask for installation CD every time
This is from the installation manual http://www.debian.org/releases/stable/i386/

• Go to root terminal and type #gedit /etc/apt/sources.list 
• Comment out the debian installation iso option at the top
• Come back to root terminal and type #apt-get update

3. Include Mint Debian repository in Debian
I did this to install Firefox but unfortunately it was in Dutch whereas I needed English-US

• Go to root terminal and type #gedit /etc/apt/sources.list 
• Add at the end deb http://packages.linuxmint.com debian import
• Go to root terminal and type 

#apt-get update

#apt-get remove iceweasel 

#apt-get install firefox

• Iceweasel will be removed and Firefox installed.

4. To install Adobe flash player
The default flash player won't play a lot of videos for me. Hence, I installed Adobe flash player 11 directly from Adobe site.

• First uninstall default flash player by #apt-get remove gnash
• Download latest Firefox install_flash_player_11_linux.i386.tar.gz from Adobe site, store it in downloads and exit Firefox or any web browser.
• Hit root terminal and type

#cd ./Downloads
#tar xvf install_flash_player_11_linux.i386.tar.gz
#cp libflashplayer.so /usr/lib/mozilla/plugins/
#cd ./usr/bin
#cp flash-player-properties /usr/local/bin


Now once you restart Firefox, by default it will use the Adobe Flash Player for live streaming or playing flash videos.
