mysql-common無法卸載

我試圖完全卸載mysql以便稍後重新安裝它，在卸載所有與mysql相關的軟體包後，mysql-common似乎仍處於損壞狀態。

$ sudo dpkg -l | grep mysql
pc  mysql-common                                  5.6.28-0ubuntu0.15.10.1                      all          MySQL database common files, e.g. /etc/mysql/my.cnf

但是運行 apt-get remove

$ sudo apt-get remove mysql-common

或使用 --purge

另外，我已經刪除了所有 mysql 相關的目錄和檔案。

我怎麼才能擺脫這個揮之不去的破損包裹？

如果某些依賴項消失，或者某些設定檔因某種原因被刪除，則某些軟體包無法卸載。您最終會得到一個未完全安裝或未完全卸載的軟體包。

在這種情況下，解決方案就是sudo apt-get install封裝。如果需要，請執行sudo apt-get install --reinstall [package].缺少的檔案將被加入到系統中，並且任何缺少的依賴項都會即時安裝。然後可以按照通常的方式完全卸載該軟體包：sudo apt-get remove [package]。

如果apt-get因為其他（依賴）問題而拒絕重新安裝該軟體包，則只能使用apt-get下載軟體包並dpkg直接使用來安裝：

apt-get download mysql-common
sudo dpkg -i mysql-common_*.deb
sudo apt-get install -f

有時您可以跳過下載，因為 Apt 傾向於保留先前下載和安裝的軟體包的存檔，/var/cache/apt/archives/以便您可以直接從第二步開始：

sudo dpkg -i /var/cache/apt/archives/mysql-common_*.deb
