(1) Go to terminal (via Accessories. It is better to have a shortcut placed
in your desktop)
(2) Type *sudo gedit /etc/apt/sources.list*
(3) Comment out all the lines by prefixing a *#* for each line. (or you can
press Cntrl+A and then delete to remove all the lines which is not
recommended)
(4) Add the following lines at the end,

*deb ftp://ftp.iitm.ac.in/ubuntu oneiric main restricted multiverse universe
**deb ftp://ftp.iitm.ac.in/ubuntu oneiric-updates main restricted
multiverse universe*
*deb ftp://ftp.iitm.ac.in/ubuntu oneiric-security main restricted
multiverse universe*
*deb ftp://ftp.iitm.ac.in/ubuntu oneiric-proposed main restricted
multiverse universe*
*deb ftp://ftp.iitm.ac.in/ubuntu oneiric-backports main restricted
multiverse universe*

(5) Save by clicking Cntrl+S
(6) Close the gedit window
(7) Open Synaptic Package Manager by giving *sudo synaptic* in the terminal
(8) Click reload
(9) After the index is updated, click "mark all upgrades"
(10) Click "Apply"
(11) Wait till the updates are downloaded and installed, occasionally
during installation you will have to stop some programs which the update
program will prompt you.



I hope this solves all your issues.
