debian package version epoch
The version string of a Debian package, as displayed by the dpkg -l
command, follows this format: [epoch:]upstream_version[-debian_revision]
. Only the upstream_version
part is required, and the other parts are optional.
See the description of the debian-package-version inspector for more information.
The inspector debian package version epoch
returns the epoch
part of the string or an empty string, if that part is absent. The epoch is an unsigned integer, typically a small number. The epoch allows the package provider to create a fresh start with version numbering schemes.
The name structure of Debian package versions is documented here.
