What does the version number in Debian mean?
This part of the version number specifies the version of the Debian package based on the upstream version. It may contain only alphanumerics and the characters + . ~ (plus, full stop, tilde) and is compared in the same way as the upstream-version is. It is optional; if it isn’t present then the upstream-version may not contain a hyphen.
How to check the package name in Debian?
Checking the package name associated with a particular Debian archive file (.deb file) can be done in one of these ways: inspect the “Packages” file in the directory where it was stored at a Debian FTP archive site. This file contains a stanza describing each package; the first field in each stanza is the formal package name.
Which is the version number of the deb file?
It is usually the version number of the original (“upstream”) package from which the .deb file has been made, if this is applicable. Usually this will be in the same format as that specified by the upstream author (s); however, it may need to be reformatted to fit into the package management system’s format and comparison scheme.
Which is a frontend for the Debian package system?
(The program apt-get can be used as a frontend for dpkg-source .) Installation of software by the package system uses “dependencies” which are carefully designed by the package maintainers. These dependencies are documented in the control file associated with each package.
How does the package management system ( dpkg ) work?
If a user attempts to install gcc without having first installed binutils, the package management system (dpkg) will send an error message that it also needs binutils, and stop installing gcc. (However, this facility can be overridden by the insistent user, see dpkg(8) .)

What’s the difference between native and non-native versions of Debian?
Native package (Debian package = Upstream software): 123 Package version = Upstream version. Non-native package: 123-3 123 = Upstream software version. 3 = Debian revision, increments if only the packaging has changed between two package releases.
Do you need a hyphen for a Debian version?
It is optional; if it isn’t present then the upstream-version may not contain a hyphen. This format represents the case where a piece of software was written specifically to be turned into a Debian package, and so there is only one “debianisation” of it and therefore no revision indication is required.
