Thanks in advance.


The top few lines of
apt-cache showpkg <package name>
give version information.


That works well & provides required dependencies etc. However if you
just want a short, simple output I just use the '-s' option to simulate
an install. For example:

$ sudo apt-get install -s atomix
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following extra packages will be installed:
atomix-data
The following NEW packages will be installed:
atomix atomix-data
0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Inst atomix-data (2.14.0-1 Ubuntu:8.04/hardy)
Inst atomix (2.14.0-1 Ubuntu:8.04/hardy)
Conf atomix-data (2.14.0-1 Ubuntu:8.04/hardy)
Conf atomix (2.14.0-1 Ubuntu:8.04/hardy)

Note that the above doesn't actually install anything, intead it just
simulates the install.

And using apt-cache showpkg:

$ apt-cache showpkg atomix
Package: atomix
