我是Ubuntu的长期用户，但我没有关注社区的最后几个版本。我刚刚完成了Oneiric的默认默认最小amd64安装，并且为特定应用程序需要32位JRE。我上次在10.10上执行了此操作，因此我对多体系结构的东西并不熟悉。我没有安装ia32-libs，而是阅读了一下并尝试：
aptitude install default-jre-headless:i386
但这只是让我明白了：
The following NEW packages will be installed:
default-jre-headless{b} openjdk-6-jre-headless{ab}
The following packages are RECOMMENDED but will NOT be installed:
icedtea-6-jre-cacao icedtea-6-jre-jamvm
0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded.
Need to get 27.3 MB of archives. After unpacking 82.1 MB will be used.
The following packages have unmet dependencies:
default-jre-headless: Depends: java-common which is a virtual package.
openjdk-6-jre-headless: Depends: openjdk-6-jre-lib (>= 6b23~pre10-0ubuntu5) which is a virtual package.
Depends: ca-certificates-java which is a virtual package.
Depends: tzdata-java which is a virtual package.
Depends: java-common (>= 0.28) which is a virtual package.
Depends: libcups2 but it is not going to be installed.
Depends: liblcms1 but it is not going to be installed.
Depends: libjpeg62 but it is not going to be installed.
Depends: libnss3-1d (>= 3.12.9+ckbi-1.82-0ubuntu4) but it is not going to be installed.
Depends: libc6 (>= 2.11) but it is not going to be installed.
Depends: libfreetype6 (>= 2.2.1) but it is not going to be installed.
Depends: libgcc1 (>= 1:4.1.1) but it is not going to be installed.
Depends: libstdc++6 (>= 4.1.1) but it is not going to be installed.
Depends: zlib1g (>= 1:1.1.4) but it is not going to be installed.
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) default-jre-headless [Not Installed]
2) openjdk-6-jre-headless [Not Installed]

aptitude是否未安装依赖项的32位版本？什么是正确的方法？如果可能的话，我可能会希望同时使用64位和32位JRE。
多体系结构支持仍处于早期阶段。在11.10中，有足够多的多体系结构用于Flash和Skype。在12.04版中，它将介绍ia32-libs所做的所有工作，但不包括其他所有内容。这将花费数年，尽管最受欢迎的部分可能会排在第一位。
