Question

and E:Some index files failed to download,they have been ignored,or old ones used instead. what i am doing with that code "apt-get update"?

Answer 1

first you need to remove the Repository(URLS) that is not able to fetch from /etc/apt/sources.list

Then you run: 1:
aptitude clean (cleans all .deb "package stock" in /var/cache/apt/archives) (cleans all .deb "package stock" in /var/cache/apt/archives)

2

aptitude update

3

 aptitude full-upgrade

Good luck!
