Question 1)

Open a Terminal from the menu Applications->Accessories->Terminal

Tip: right click with mouse on the terminal title caption and select the item "Always on Top" doing this you will force the terminal window to stay on top of the other windows and you will find very easy to copy single row from this web page into the terminal...
Something more about using the terminal https://help.ubuntu.com/community/UsingTheTerminal

Then type or better copy and paste a row a time then press enter:
(Tip: select the single row to copy then right click into the terminal and to quick paste click with middle button of mouse )

sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update

give your user password when requested, you don't see nothing when you type it, then press enter.

Please do this procedure then for the other questions please split them into single question

Hope this helps

most likely our indian software server is faulty it is not having the updates...I changed it manually to netherlands / Singapore because that was giving very good speed and alll the updates are there. So change the server in synaptic so that all the updates you get either from main server or any other but not from India
Install VLC Player as it has built in codec support by default so you will be able to play all popular formatsa
Updates will come automatically when you change the server.
That should solve your problem

Can you help with this problem?
