Apt-get: how to check version number before installation?

[M Gutierrez]

Hello, 

i am new to the forum and I am interested to know if it's possible to make a live cd from simply downloading an ubuntu cd? Please, I would like to try Ubuntu and I know it takes a long time to get on from snail mail so I would really like to make a live cd. 

Thanks in advance.

Sincerely,

Mike

apt-cache policy <package>

is better.  It tells you exactly which versions are available at every
repository in your sources.  It also helps explain why you're getting
 the
wrong versions if you use apt pinning! E.G. (bella is my local cache -
created with apt-move; /var/lib/dpkg/status should always be the
 currently
installed version):

$ apt-cache policy firefox
firefox:
  Installed: 2.0.0.11+2nobinonly-0ubuntu0.7.10
  Candidate: 2.0.0.11+2nobinonly-0ubuntu0.7.10
  Version table:
 *** 2.0.0.11+2nobinonly-0ubuntu0.7.10 0
