How to Check Version of Updated Package in Ubuntu

aptpackage-managementupgrade

I'm running apt-get upgrade and see list of available packages which could be upgraded. Some of them without any version, how can I figure out what package version apt want to install here?

For example I see the next picture: 

 base-files .. redmine redmine-mysql redmine-sqlite ...

How to know what to what version redmine will be upgraded ? And from what repository apt going to take it?

To see the versions of a package you could use:

apt-cache show redmine | grep -i version

Output is:

Version: 1.3.2+dfsg1-1ubuntu1

To see the versions and the repository you could use:

apt-cache policy redmine

Output is:

redmine:
  Installiert: (keine)
  Kandidat:    1.3.2+dfsg1-1ubuntu1

     1.3.2+dfsg1-1ubuntu1 0
