安装 odbcins1debian2，Ubuntu 20.04 LTS 上的依赖关系已损坏

我正在尝试在 Ubuntu 20.04 上安装 odbcinst1debian2，但似乎缺少依赖项“multiarch-support”：

$ sudo apt-get install odbcinst1debian2
Reading package lists... Done

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 odbcinst1debian2 : PreDepends: multiarch-support but it is not installable
E: Unable to correct problems, you have held broken packages.

之后运行sudo apt-get install -f并不能解决问题。

$ sudo apt-get install -f

由于这个软件包需要多架构支持，我尝试直接安装它，但这也无济于事：

$ sudo apt-get install multiarch-support

Package multiarch-support is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'multiarch-support' has no installation candidate

该包和依赖于它的unixodbc-dev该如何安装？

$ sudo apt-get install unixodbc-dev

任何帮助都将不胜感激，谢谢。

我已经运行了apt-get update，这是我在新安装上运行的第一件事。

$ sudo apt-get install odbcinst1debian2

答案1

sudo apt-get update这个问题看起来好像你在安装前忘记运行了odbcinst1debian2。焦点这个包不依赖在multiarch-support。

顺便一提multiarch-support可以手动安装：

cd ~/Downloads
wget http://archive.ubuntu.com/ubuntu/pool/main/g/glibc/multiarch-support_2.27-3ubuntu1.4_amd64.deb
sudo apt-get install ./multiarch-support_2.27-3ubuntu1.4_amd64.deb

答案2

我不得不sudo apt-get install unixodbc 前添加微软的源列表，这里。

答案3

正如评论和其他答案所解释的那样，该问题源于微软宣传该软件包的较新版本。

但是，您可以保留 Microsoft 存储库并在以下位置为其设置优先级较低的策略/etc/apt/preferences ：

Package: *
Pin: origin "packages.microsoft.com"
Pin-Priority: 1

然后使用apt-get update并重试升级。
