我已經安裝了 11.04 和 Gnome 3，一切都工作正常，直到我嘗試執行更新管理器。現在我無法更新我的任何軟體包。一個相似的問題不久前發布過，但沒有提出解決方案

sudo apt-get install [package]安裝每個被阻止的軟體包（通過 ）後，一切似乎都很正常。那為什麼我必須重新安裝一切呢？我假設它與 gnome3 有關，因為每個軟體包都是透過他們的儲存庫安裝的。
答案1
我發現有時套件管理器無法應對特定 PPA 請求更新的變更範圍。
例如，管理器開始處理文件，但放棄聲明錯誤的依賴關係 - 沒有進一步分析 PPA 中的後續套件或多個套件是否會滿足該依賴關係。
在這些情況下，您應該執行以下操作 - 在終端機中運行
sudo apt-get update && sudo apt-get upgrade
這將為您提供無法安裝的軟體包清單。
一項一項地瀏覽清單嘗試安裝它，即
sudo apt-get install <package name>
完成此操作後，重複更新/升級命令並重複其請求的其餘套件/新套件。您可能需要執行幾次此操作，直到安裝完所有軟體包。
