无法使用终端卸载php-memcache

我使用命令从计算机上卸载了php5

sudo apt-get -y purge php.*

运行此命令将在终端显示此消息：

Errors were encountered while processing: php5-memcache php5-memcached

所以我尝试卸载memcache：

sudo apt-get remove php-memcache

它向我显示了一条消息，它找不到memcache软件包：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package php-memcache

然后进行memcached：

apt-get remove php5-memcached

它向我抛出有关php中缺少依赖项的信息：

The following packages have unmet dependencies.
php5-memcache : Depends: php5-common (>= 4.3.11) but it is not going to be installed  
      Depends: php-pear (>= 1.4.0~b1) but it is not going to be installed
      Depends: phpapi-20121212
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

跑步

apt-get -f install

再次抛出有关删除内存缓存的错误。

据我正确理解，我犯了一个错误，我没有在卸载php5之前删除memcache？我现在能做什么？我需要再次安装php吗？当我尝试安装缺少的依赖项时，我收到有关另一个缺少的软件包的消息。使用“ apt-get”时，是否应该缺少自动添加/删除的软件包？

通过谷歌搜索我发现，问题可能出在使用不适合我的系统的错误存储库。如何检测哪些存储库适合我的系统安装/卸载用于卸载Memcache的适当软件包？谢谢你的帮助

我已经将这样的php存储库添加到我的系统中：http : //ppa.launchpad.net/ondrej/php5/ubuntu http://ppa.launchpad.net/ondrej/php5/ubuntu http://ppa.launchpad.net/ ondrej / php-7.0 / ubuntu http://ppa.launchpad.net/ondrej/php-7.0/ubuntu

我尝试根据@oerdnj用dpkg删除memcache，但仍然出现一些错误：

tomas@Toshiba ~ $ sudo dpkg --purge php5-memcache
(Reading database ... 275094 files and directories currently   installed.)
Removing php5-memcache (3.0.8-4build1) ...

dpkg: error processing package php5-memcache (--purge):

我还尝试了线程解决方案如何删除/安装未完全安装的软件包？但它向我显示了相同的错误：

tomas@Toshiba ~ $ sudo apt-get install --reinstall dpkg

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies.
php5-memcache : Depends: php5-common (>= 4.3.11) but it is not going      to be installed
Depends: php-pear (>= 1.4.0~b1) but it is not going to be installed
             Depends: phpapi-20121212
php5-memcached : Depends: libmemcached10 but it is not going to be installed
              Depends: php5-common (>= 5.2.0) but it is not going to be installed
              Depends: php5-common (< 6.0.0) but it is not going to be installed
              Depends: php-pear (>= 1.4.0~b1) but it is not going to be installed
