我正在使用 ubuntu 14.04 我不知道不知何故我在螢幕上看到了紅色符號，如下所示：
當我嘗試使用sudo apt-get upgrade它進行升級時，它會拋出錯誤：
$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
click : Depends: python3-click-package (= 0.4.45.1+16.10.20160916-0~619~ubuntu14.04.1)
E: Unmet dependencies. Try using -f.
當我輸入時，sudo apt-get -f install它會拋出另一個錯誤：
$ sudo apt-get -f install

我嘗試安裝在谷歌上找到的每個命令，但是唉:(
請指導我如何解決這個錯誤
答案1
您無意中嘗試在 Ubuntu 14.04 上安裝包含與您安裝的版本不相容的程式庫的軟體包。您必須刪除有問題的並安裝適合您的 Ubuntu 版本的軟體包。
您的錯誤表明您的click包裹python3-click-package至少需要0.4.45.1+16.10.20160916-0~619~ubuntu14.04.1。python3-click-packageUbuntu 16.04的版本是0.4.43+16.04.20170613-0ubuntu1。這低於0.4.45您失敗的click安裝需求。
順便說一下python3-click-package版本0.4.45.1+16.10.20160916-0~619~ubuntu14.04.1是 Ubuntu 17.04 儲存庫的一部分。
您可以透過以下步驟修復庫不符的問題：
執行以下步驟來解決您的問題。在此過程中您會收到警告和錯誤。您將不得不多次循環執行這些步驟。每個循環將執行一些後續清理並提供有關如何繼續的資訊。
開始：
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade
如果您看到autoremove指令執行：
$ sudo apt-get autoremove
現在檢查是否需要重新啟動。運行這個：
$ [[ -f /var/run/reboot-required ]] && echo "Reboot Now"
如果需要重新啟動，請先重新啟動，然後再繼續。
現在修復有問題的應用程式：
$ sudo apt remove click --purge
$ sudo apt remove python3-click-package --purge
$ sudo apt autoremove
$ sudo apt install click
$ sudo apt remove python3-click-package
$ sudo apt autoremove
當允許系統自動執行更新和升級時，這些手動命令在正常操作期間是無縫的。在進行手動維護時，有些則顯得非常多餘。它們是必要的。
