APT 保留损坏的安装

我正在使用 Debian 9.5，最近卸载了一个软件包 ( mariadb)，现在当我尝试安装新软件包时，我不断收到以下消息：

E: Unable to correct problems, you have held broken packages.

我已经尝试过这些命令但没有结果：

sudo dpkg --configure -a
sudo apt-get install -f
apt-get install --fix-broken

我还运行了此命令来显示损坏的软件包，但它没有显示任何内容：

apt-mark showhold

即使当我尝试运行 sudo 时apt-get upgrade我也会得到这个：

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

然后我能够安装 aptitude 包管理器（不知道如何），并尝试安装新包，sudo aptitude install mysql-server它显示了一些内容：

The following packages have unmet dependencies:
 libdbi-perl : Depends: perlapi-5.24.1 which is a virtual package, provided by:
                        - perl-base (5.24.1-3+deb9u4), but 5.26.2-7 is installed

 libfcgi-perl : Depends: perlapi-5.24.1 which is a virtual package, provided by:
                         - perl-base (5.24.1-3+deb9u4), but 5.26.2-7 is installed

 libterm-readkey-perl : Depends: perlapi-5.24.1 which is a virtual package, provided by:
                                 - perl-base (5.24.1-3+deb9u4), but 5.26.2-7 is installed

 libdbd-mysql-perl : Depends: perlapi-5.24.1 which is a virtual package, provided by:
                              - perl-base (5.24.1-3+deb9u4), but 5.26.2-7 is installed

The following actions will resolve these dependencies:

      Keep the following packages at their current version:         
1)      default-mysql-server [Not Installed]                        
2)      libcgi-fast-perl [Not Installed]                            
3)      libdbd-mysql-perl [Not Installed]                           
4)      libdbi-perl [Not Installed]                                 
5)      libfcgi-perl [Not Installed]                                
6)      libterm-readkey-perl [Not Installed]                        
7)      mariadb-server-10.1 [Not Installed]                         
8)      mysql-server [Not Installed]                                

      Leave the following dependencies unresolved:                  
9)      libcgi-pm-perl recommends libcgi-fast-perl (>= 1:2.01)      
10)     mariadb-client-10.1 recommends libdbd-mysql-perl (>= 1.2202)
11)     mariadb-client-10.1 recommends libdbi-perl                  
12)     mariadb-client-10.1 recommends libterm-readkey-perl

这是的输出apt policy pearl-base：

 perl-base:    
    Installed: 5.26.2-7    
    Candidate: 5.26.2-7    
    Version table:

您的存储库中有测试，优先级为 500，与稳定存储库相同；这实际上意味着您正在运行 Debian 测试，而不是 Debian 9.5。 （感谢您帮助测试 Debian 的下一个版本！）

mysql-server目前在测试中不可用，因此apt install mysql-server（或其变体）尝试在 Debian stable 中安装该版本；但这需要 Perl 的 Debian 稳定版，而不是 Debian 测试版，因此安装无法继续。

为了解决这个问题，我建议恢复到 Debian 稳定版。如果你想继续测试，你必须等待 MySQL 迁移到那里，或者切换到混合测试/不稳定设置。
