コロンの前の数字、つまりコロンの中の数字が何を意味するのか知りたいです。2:1.12.4-6
答え1
これDebian のバージョン番号次の形をしています
[epoch:]upstream_version[-debian_revision]
どこ
epoch
以前のバージョンのパッケージのバージョン番号のエラーを許可するために含まれる(通常は小さい)符号なし整数。省略するとepoch
ゼロとみなされます。upstream_version
通常、.debファイルが生成されたソースソースパッケージのバージョン番号。通常、アップストリームソースで使用されているのと同じ形式で保持されます。debian_revision
アップストリームバージョンに基づいてDebianパッケージのバージョンを指定します。これはオプションで、ソフトウェアがDebianパッケージ用に特別に作成されている場合は省略されます。

はい連帯。
より包括的に、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).
