It can be confusing...

$ bash --version
GNU bash, version 4.0.33(1)-release (i486-pc-linux-gnu)

$ apt-cache policy bash
bash:
  Installed: 4.0-5ubuntu2
  Candidate: 4.0-5ubuntu2
  Version table:
 *** 4.0-5ubuntu2 0
        500 http://archive.ubuntu.com karmic/main Packages
        100 /var/lib/dpkg/status

As you can see, it's _not_ 4.0.5, it's actually 4.0.33 (in Ubuntu
language: 4.0-5ubuntu2).

@Peng Yu: for your search, use:
http://packages.ubuntu.com/search?suite=all&searchon=names&keywords=bash
and you'll see 'Package bash' and the versions for all from dapper to lucid.
