无法安装某些软件包。取决于： x 但要安装 x

Question

我使用的是 64 位系统，我怀疑这就是造成此问题的原因。我正在尝试安装各种软件包，其中之一是libssl-dev.

$ sudo apt-get install libssl-dev 
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libssl-dev : Depends: libssl1.0.0 (= 1.0.1f-1ubuntu2) but 1.0.1f-1ubuntu2.8 is to be installed
              Recommends: libssl-doc but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

我尝试sudo apt-get -f install按照网站上类似问题中的建议进行操作。但这就是我得到的：

$ sudo apt-get -f install 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我在网站上进行了更多研究，有人建议手动安装缺少的软件包。所以我也做了同样的事情：

$ sudo apt-get install libssl1.0.0 Reading package lists... Done
Building dependency tree       
Reading state information... Done
libssl1.0.0 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded

在这里您可以看到，该软件包已经安装。

所以我的猜测是我的系统正在尝试安装 64 位版本libssl-dev，但找不到 64 位版本libssl1.0.0。如果手动安装，我的系统显示我libssl1.0.0怀疑是 32 位版本。

我还有更多的软件包需要安装，它们都感染了这个错误。

Answer 1

强制降级libssl1.0.0

sudo apt-get install libssl1.0.0=1.0.1f-1ubuntu2

安装的版本1.0.1f-1ubuntu2.8阻止安装libssl-dev

你应该紧急更新你的机器。当前版本是1.0.1f-1ubuntu2.15

打开Software & Updates并标记trusty-security和trusty-updates

在那之后

sudo apt-get update
sudo apt-get dist-upgrade

不，sudo apt-get dist-upgrade 不安装 Vivid。
