Hi,

Your GPG error can probably be fixed by the solutions in this blog post (http://cortman.wordpress.com/2012/02/27/how-to-fix-gpg-errors-in-ubuntu/).
The cdrom repositories can probably be safely deleted, unless you have a complete set of software CDs and are installing from them. Do this by editing your sources.list file:


gksu gedit /etc/apt/sources.list

Find the lines that refer to cdrom:, delete them and save. Then run


sudo apt-get update

Good luck!

open update manager -> settings -> in the first tab uncheck the CD-ROM check box .

&
open your terminal and type this


sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update

and let us know what you got .
All the best .

still got that error at the end but no more red triangle in my status bar so yay for that!!
this whole thing started because i was trying to get java to work on this machine...was working fine until i upgraded from 11.04 to 11.10...i still dont know what to do to make it work...tried JDK and JRE and any other acronym you can think of if anyone has any advice as far as that goes please let me know.

Thanks...ToAsT

c/p fixed it for me

sudo gpg --export --armor 2EA8F35793D8809A | sudo apt-key add -

took the referance from

http://amazing-development.com/archives/2006/02/24/fixing-gpg-errors-with-apt-get-for-dummies-like-me/

have a good day all.

- 36minutes later same error one diffrent pc.
Solution is c/p your key instead of the 2EA8 ect.

sudo gpg --export --armor "your key here" | sudo apt-key add -
