无法在 Jammy 上安装 libc6:i386

Question

最新的amd64Jammy 安装。

% cat /etc/issue
Ubuntu 22.04.1 LTS \n \l

% dpkg --print-foreign-architectures
i386

% dpkg -l libc6
Desired=Unknown/Install/Remove/Purge/Hold

||/ Name           Version         Architecture Description

ii  libc6:amd64    2.35-0ubuntu3.1 amd64        GNU C Library: Shared libraries
in  libc6:i386     <none>          i386         (no description available)
               

据我所知，以下内容阻止libc6:i386安装：

% sudo dpkg -i libc6_2.35-0ubuntu3.1_i386.deb
...
(Reading database ... 228990 files and directories currently installed.)
Preparing to unpack libc6_2.35-0ubuntu3.1_i386.deb ...
Unpacking libc6:i386 (2.35-0ubuntu3.1) ...
dpkg: error processing archive libc6_2.35-0ubuntu3.1_i386.deb (--install):
 trying to overwrite shared '/usr/share/doc/libc6/NEWS.Debian.gz', which is different from other instances of package libc6:i386
Processing triggers for libc-bin (2.35-0ubuntu3.1) ...
Errors were encountered while processing:
 libc6_2.35-0ubuntu3.1_i386.deb

两个问题：

1. 如何恢复indpkg 中 i386 软件包的状态？软件包安装了一半，让系统看起来很乱，这是很可悲的；
2. 以上是 Ubuntu 打包中的临时错误吗？我要向 Canonical 提交错误吗？我不想尝试手动删除有问题的NEWS.Debian文件，因为我不想冒系统稳定性的风险，谁知道还有哪些进一步的冲突......

作为 PS，运行ubuntu-bug libc6最终会产生相当“有趣”的输出：

% ubuntu-bug libc6

The problem cannot be reported:

This does not seem to be an official Ubuntu package.

Answer 1

事实证明，由于某种原因，我的部分sources.list丢失了（它同时具有和部分）。jammy-updatesjammyjammy-security

我添加后

deb http://mirror/ubuntu/ jammy-updates main restricted

和类似的条目universe/multiverse，我能够libc6:i386通过基本apt-get update/install方式安装。
