apt-get configuration

[Sergey Lukin <lukin.s.v@gmail.com>]

Dear All,

System has around 20 software modules.
Each module is a Debian package.
If the module is not present in the system dummy functionality will be called.
All modules are retrieved from the local Debian repository and installed using APT 

The problem is that if somebody types 
$apt-get upgrade or
$apt-get install moduleX
This will automatically upgrade the system to the latest version. But this is not what is really wanted.

Is there a way to forbid using only module name without version number ?

Say if somebody types 
$apt-get install moduleX -- APT shows an error message
$apt-get install moduleX-001 -- APT installs it.

Kind regards,

Sergey Lukin
