APT 保留損壞的安裝

我正在使用 Debian 9.5，最近卸載了一個軟體包 ( mariadb)，現在當我嘗試安裝新軟體包時，我不斷收到以下訊息：

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

我已經嘗試過這些命令但沒有結果：

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

我還運行了此命令來顯示損壞的包，但它沒有顯示任何內容：

apt-mark showhold

即使當我嘗試運行 sudo 時apt-get upgrade我也會得到這個：

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

然後我能夠安裝 aptitude 套件管理器（不知道如何），並嘗試安裝新套件，sudo aptitude install mysql-server它顯示了一些內容：

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

這是的輸出apt policy pearl-base：

 perl-base:    
    Installed: 5.26.2-7    
    Candidate: 5.26.2-7    
    Version table:    
 *** 5.26.2-7 500

您的儲存庫中有測試，優先權為 500，與穩定儲存庫相同；這實際上意味著您正在運行 Debian 測試，而不是 Debian 9.5。 （感謝您幫助測試 Debian 的下一個版本！）

mysql-server目前在測試中不可用，因此apt install mysql-server（或其變體）嘗試在 Debian stable 中安裝該版本；但這需要 Perl 的 Debian 穩定版，而不是 Debian 測試版，因此安裝無法繼續。

為了解決這個問題，我建議恢復到 Debian 穩定版。如果你想繼續測試，你必須等待 MySQL 遷移到那裡，或切換到混合測試/不穩定設定.
