我嘗試安裝琥珀工具。但是當我按照安裝手冊進行操作時，系統告訴我要安裝以下依賴項：
sudo apt-get install csh flex gfortran g++ xorg-dev \
zlib1g-dev libbz2-dev patch python-tk python-matplotlib
這給了我以下錯誤：

我sudo apt-get update在運行這個之前確實運行過，但它沒有改變任何東西。
如何修復這些軟體包並安裝這些依賴項？

其中一些套件存在於 Universe 儲存庫中。由於明顯的原因，不安裝它會導致安裝失敗。您可以透過更新管理器設定或簡單地透過以下方式啟用此功能：
sudo add-apt-repository universe
然後sudo apt-get update再次返回安裝。
