合併列表問題
當你在終端中運行更新命令時，你可能會碰到這個錯誤“合併列表錯誤”，就像下面這樣：
E:Encountered a section with no Package: header,
E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.comubuntudistspreciseuniversebinary-i386Packages,
E:The package lists or status file could not be parsed or opened.’
可以使用以下命令來修復該錯誤：
sudo rm -r /var/lib/apt/lists/*
sudo apt-get clean && sudo apt-get update
下載倉庫信息失敗 -1
實際上，有兩種類型的下載倉庫信息失敗錯誤。如果你的錯誤是這樣的：
W:Failed to fetch bzip2:/var/lib/apt/lists/partial/in.archive.ubuntu.comubuntudistsoneiricrestrictedbinary-i386Packages Hash Sum mismatch,
W:Failed to fetch bzip2:/var/lib/apt/lists/partial/in.archive.ubuntu.comubuntudistsoneiricmultiversebinary-i386Packages Hash Sum mismatch,
E:Some index files failed to download. They have been ignored, or old ones used instead
那麼，你可以用以下命令修復：
sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update
