我試圖將 PHP 降級回 5.4（升級後我的網站變得非常慢）。我按照本指南的第一步進行操作：如何在 Ubuntu 14.04 中將 PHP 從 5.5.9 降級到 5.4（使用 LAMP 安裝）
現在我無法再安裝 PHP5

dpkg: error processing package phpmyadmin (--remove):

Errors were encountered while processing:

我該如何解決這個問題？
我試圖完成安裝，apt-get -f install但得到了：
Reading package lists... Done

試著重啟，情況還是一樣

Apt 資料庫已鎖定。其他人只是想安裝其他東西。也許您在另一個終端機中，或者您正在運行 Synaptic 套件管理器。嘗試透過 grep 您的進程來找到它：
ps -ef | grep apt
或者
ps -ef | grep synaptic
只需嘗試退出或使用kill -15 終止此應用程序，然後嘗試再次安裝。
