ubuntu 上无法安装 mysql？

我尝试了几种方法，从终端，现在从软件中心，但出现此错误：

mysql-client-5.6: Depends: libwrap0 (>= 7.6-4~) but 7.6.q-25 is to be installed
                  Depends: zlib1g (>= 1:1.2.0) but 1:1.2.8.dfsg-1ubuntu1 is to be installed

如何修复此问题？发生了什么？

尝试过这个：

您的系统出现故障，有一些未升级的软件包。

sudo apt-get install -f
sudo apt-get update
sudo apt-get dist-upgrade

现在重新安装perl-base：

sudo apt-get install --reinstall perl-base

但现在的问题是：

Reading package lists ... Done
Building dependency tree
Reading state information ... Done
Reinstallation of the perl-base is not possible, it can not be retrieved.
0 upgrade, 0 newly installed, 0 to remove and 0 not upgraded.

非常有趣，现在我们尝试这样做：

apt-get download perl-base

哦不！

E: Can't find a source to download version '5.20.1-1' of 'perl-base:amd64'

非常非常...好的，下次再试：

wget http://mirrors.kernel.org/ubuntu/pool/main/p/perl/perl-base_5.18.2-2ubuntu1_amd6%E2%80%8C%E2%80%8B4.deb

和哦哦...

好的，最后一次尝试，打开http://packages.ubuntu.com/trusty/amd64/perl-base/download使用浏览器并安装：

sudo dpkg -i perl-base_5.18.2-2ubuntu1_amd64.deb

现在我们突然遇到了混合分布的问题/etc/apt/sources.list。apt-cache policy …显示 Trusty 并lsb_release -a给出信息：

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 14.10
Release: 14.10
Codename: utopic

执行：

sudo sed -i 's/trusty/utopic/' /etc/apt/sources.list

或者删除该文件并使用 创建一个新文件Software & Updates。之后执行：

sudo apt-get update
sudo apt-get install -f
sudo apt-get dist-upgrade

最后...

sudo apt-get install mysql-client

对于未来的读者以下是聊天内容。

在接下来的几天内，将您的系统升级到 Wily。Utopic 不再受支持。
