我在執行時遇到錯誤apt-get update：
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
perl : Depends: perl-modules (>= 5.18.2-2ubuntu1.1) but 5.18.2-2ubuntu1 is installed
E: Unmet dependencies. Try using -f.
所以我手動下載perl_5.18.2-2ubuntu1.1.debian.tar.gz了https://launchpad.net/ubuntu/+source/perl/5.18.2-2ubuntu1.1。當我解壓縮該tar.gz檔案時，它會提供一個包含一些檔案的 debian 資料夾。
現在我要怎麼消除這個錯誤呢？
輸出apt-cache policy：

對此不太確定，但看起來您已經破壞了依賴關係。從選單打開終端機並使用以下命令啟動：
sudo aptitude update && sudo aptitude install gtkorphan
如果第一個命令成功運行，則使用 && 運行第二個命令。
繼續運行：
sudo aptitude update && sudo aptitude upgrade
這用於仔細檢查您是否擁有所有更新。
若要清除損壞的包，請使用以下命令：
sudo aptitude -f
它提供了一個漂亮的介面來搜尋、導航、安裝、更新和以其他方式管理套件。
請注意互換使用 aptitude 和 apt-get 是不好的做法，因為它們分別記錄使用者所做的更改
