I read the article on your website titled “How To Customize The GRUB Boot Loader Using BURG [Ubuntu]” and was trying installing BURG on Ubuntu 11.04.
After running the second step, which says to enter “sudo apt-get update && sudo apt-get install burg” in the command line, the Terminal starts downloading, however, gives the following message because of which I am unable to proceed. please help. Thanks!
