How can I check the version before installing a package using 'apt-get'?

I'm thinking to install hylafax+ version 5.5.4 which was released last month on my Debian PC.

I checked dpkg -l | grep "hylafax" and found out that the current version is 5.5.3. Then I checked apt-cache search hylafax and saw the packages are available, but I can't see any version number.

How can I find the version of packages available in the apt-get?

Solution

  • OK, I found it.

    apt-cache policy <package name> will show the version details.

    It also shows which version is currently installed and which versions are available to install.

    For example, apt-cache policy hylafax+
