Package ia32-libs-gtk is a virtual package provided by:
ia32-libs 2.2ubuntu11
You should explicitly select one to install.


装32位库时出现的。虚拟包?这是什么东东???
全部情况是这样的:

sudo apt-get install ia32-libs ia32-libs-gtk linux32 lib32asound2
Reading package lists... Done
Building dependency tree
Reading state information... Done
ia32-libs is already the newest version.
Package ia32-libs-gtk is a virtual package provided by:
ia32-libs 2.2ubuntu11
You should explicitly select one to install.
E: Package ia32-libs-gtk has no installation candidate

引用:
6.8 What's a Virtual Package?

A virtual package is a generic name that applies to any one of a group of packages, all of which provide similar basic functionality. For example, both the tin and trn programs are both news readers, and should therefore satisfy any dependency of a program that required a news reader on a system in order to work. They are therefore both said to provide the "virtual package" called news reader.

Similary, smail and sendmail both provide the functionality of a mail transport agent. They are therefore said to provide the virtual package, "mail transport agent". If either one is installed, then any program depending on the installation of a mail transport agent will be satisfied by the existence of this virtual package.

Debian provides a mechanism so that, if more than one package which provide the same virtual package is installed on a system, then system administrators can set one as the preferred package. The relevant command is update-alternatives, and is described further in the section on diversions.
