About the key error in http://ftp.iitm.ac.in/cran/bin/linux/ubuntu, you have explanation in the site:


Announcement: Due to sever issues, the Ubuntu CRAN packages have been signed with a new pgp key. See SECURE APT below

So you will have to add the new key in the way addressed in the web:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

Lucid has now lost its support so you will need to update to a newer ubuntu version, I'm afraid.

Forget about the duplicate sources; you will not be able to easily update any more. I suggest 12.04 as the best option for you, and if you don't want or like unity try Xubuntu 12.04 instead. Xubuntu has a more conventional DE and you will probably find that it is very like ubuntu Lucid in many ways.

+1 to ajgreeny.
Your issue is not what it says it is. Its that Lucid is dead, no more updates. You have to install 12.04.

thank you.. Does it mean no more ubuntu 10.04.?:confused:

[ngchandrasekhar]

thank you all .. But I still want to know if there is any other alternative solution rather upgrading to 12.04. Please help me thank you..Thank you again

[fantab]

Why do you want an "alternative solution rather upgrading to 12.04"? With all support for 10.04 has stopped there is no alterantive but to upgrade. Is there any special reason why you don't want to upgrade?

[claracc]

You can find more information in this link: http://askubuntu.com/questions/101479/are-existing-updates-available-after-end-of-support

Doing what this link indicates you can install software through synaptic or software center but you won't receive any update.

[p-dh]

Another solution is to try Y-PPA Manager (https://launchpad.net/~webupd8team/+archive/y-ppa-manager?field.series_filter=lucid) and let it fix the issue. 10.04 desktop has been sunsetted - 10.04 server still has two years. So, certain archives are and will be still available.
A quick addition is that I have updated all my 10.04 PCs to 12.04 - including a vastly underpowered netbook. They all run 12.04 at least as well as 10.04 with the added advantage of having desktop support through 2017.

Peace,
Paul :cool:

[ngchandrasekhar]

Thank you all for all the suggestion. The reason of retaining 10.04 was only because once I tried to upgrade to 11. 04 but it didnt goes well.. Now I have upgraded to 12.04. Thanks to all your suggestion.. but I have a small query. I found the upgrade versiono to be 32bit. As my processor is 64 bit. I want to know whether its alright or shall I download the 64 bit. Help me to know the differences between the two. Thank you again.

[fantab]

If your processor is 64bit then install 64bit Ubuntu, it will perform better than 32bit. 32bit is old technology while 64bit is newer.

[ubu_dynamite]

32bit will work just fine to 64bit consumes more ram so if your low on that stick with 32bit.

[p-dh]

If you had 32-bit 10.04 and did an in-place upgrade, you would receive the 32-bit 12.04. You cannot simply upgrade from 32-bit to 64-bit, you must do a reinstall.
For more info on the difference between 32-bit and 64-bit, here (https://help.ubuntu.com/community/32bit_and_64bit) is a good place to start. The original issues associated with running 64-bit have disappeared (I simply haven't seen any) and it's worth considering if you are doing a new install or setting up a new PC.

Peace,
Paul :cool:
