Debian dpkg 패키지 버전 번호 이해

이것을 입력하면 dpkg -l | grep xserver-xorg설치된 패키지와 해당 버전 목록이 표시됩니다.

답변1

이것데비안의 버전 번호다음과 같은 형태를 가지고 있습니다

[epoch:]upstream_version[-debian_revision]

어디

  • epoch이전 버전의 패키지에 대한 버전 번호의 오류를 허용하기 위해 포함된 (일반적으로 작은) 부호 없는 정수입니다. 생략하면 epoch0으로 간주됩니다.

  • upstream_version 일반적으로 .deb 파일이 생성된 원본 소스 패키지의 버전 번호입니다. 일반적으로 업스트림 소스에서 사용되는 것과 동일한 형식으로 유지됩니다.

  • debian_revision업스트림 버전을 기반으로 Debian 패키지의 버전을 지정합니다. 이는 선택 사항이며 소프트웨어가 Debian 패키지용으로 특별히 작성된 경우 생략됩니다.

보다 포괄적으로,man deb-version:

[epoch:]upstream-version[-debian-revision]

epoch

This is a single (generally small) unsigned integer.  It may be omitted,  in  which
case  zero  is assumed.  If it is omitted then the upstream-version may not contain
any colons.

It is provided to allow mistakes in the version numbers  of  older  versions  of  a
package,  and  also  a  package's  previous  version  numbering schemes, to be left
behind.

upstream-version

This is the main part of the version number.  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.

The comparison behavior of the  package  management  system  with  respect  to  the
upstream-version  is  described  below. The upstream-version portion of the version
number is mandatory.

The  upstream-version  may  contain  only  alphanumerics  ("A-Za-z0-9")   and   the
characters  . + - : ~ (full stop, plus, hyphen, colon, tilde) and should start with
a digit.  If there is no debian-revision then hyphens are not allowed; if there  is
no epoch then colons are not allowed.

debian-revision

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.   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.

It  is  conventional  to  restart  the  debian-revision  at  '1' each time time the
upstream-version is increased.

Dpkg will break the version number apart at the last hyphen in the string (if there
is  one)  to  determine  the upstream-version and debian-revision. The absence of a
debian-revision compares earlier than the  presence  of  one  (but  note  that  the
debian-revision is the least significant part of the version number).
