这里为什么libpango有两个？

一个是libpango-1.0-0:amd64，另一个是吗libpango1.0-0:amd64？

答案1

libpango1.0-0只是一个过渡包。过渡包的存在只是为了让升级顺利进行，如果某些包仍然依赖于这些包，这样它们就不会以未满足的依赖关系而告终。这些包通常是在原始包在某处重命名时创建的。如果没有包依赖于此包，则可以毫无问题地将其删除。

apt-cache show libpango-1.0-0 libpango1.0-0
Package: libpango-1.0-0
Description-en: Layout and rendering of internationalized text
 Pango is a library for layout and rendering of text, with an emphasis
 on internationalization. Pango can be used anywhere that text layout is
 needed. however, most of the work on Pango-1.0 was done using the GTK+
 widget toolkit as a test platform. Pango forms the core of text and
 font handling for GTK+-2.0.
 .
 Pango is designed to be modular; the core Pango layout can be used with
 four different font backends:
  - Core X windowing system fonts
  - Client-side fonts on X using the Xft library
  - Direct rendering of scalable fonts using the FreeType library
  - Native fonts on Microsoft backends
 .
 This package contains the shared libraries.

 This is a transitional package.

它们实际上是两个不同的包（虽然相当令人困惑）

实际上，libpango1.0-0 依赖于 libpango-1.0-0

快速 dpkg -L 显示
