如何以 Debian 方式取得已發佈軟體包的 .dsc 檔案？ 
DSCURL="$(wget -qO- "https://packages.debian.org/${SUITE}/${PKG}" \
    | grep -o 'http.*\.dsc">\[' | cut -d'"' -f1)"
[ -z "$DSCURL" ] && die 2 "no .dsc"
dget ${ALLOW_UNAUTH} -x "$DSCURL" 2> "$TEMP"

我正在尋找從 jessie 獲取源代碼包的 Debain 方式，以便通過dget -x $DSCURL.那是為了向後移植所以apt-get source這不是一個解決方案，它會幹擾 apt 系統的喘息。我現在正在透過解析 Debian 網頁來做到這一點。我找不到合適的Debian API。

apt-get source -t jessie dpkg 是一種方式去：

引用線上說明頁面中的相關部分

       Source packages are tracked separately from binary packages via
       deb-src lines in the sources.list(5) file. This means that you will
       need to add such a line for each repository you want to get sources
       from; otherwise you will probably get either the wrong (too old/too
       new) source versions or none at all.

並且：

   -t, --target-release, --default-release
       This option controls the default input to the policy engine; it
       creates a default pin at priority 990 using the specified release
       string. This overrides the general settings in
       /etc/apt/preferences. Specifically pinned packages are not affected
       by the value of this option. In short, this option lets you have
       simple control over which distribution packages will be retrieved
       from. Some common examples might be -t '2.1*', -t unstable or -t
       sid. Configuration Item: APT::Default-Release; see also the
       apt_preferences(5) manual page.

另一個選擇是使用debootstrap並創建一個完整的 chroot。

不要忘記使用類似的東西pbuilder擁有可靠的軟體包建置。
