無法在 Ubuntu 16.10 Yakkety 上安裝軟體包
在我的 Ubuntu 系統中安裝
gawk軟體包時，我在命令行中收到此錯誤Reading package lists... Done Building dependency tree Reading state information... Done Package gawk is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'gawk' has no installation candidate此外，通過安裝任何其他軟體包
sudo apt-get install會導致類似的錯誤。我用Google搜尋了解決方案，但似乎沒有一個工作。我的 /etc/apt/sources.list 有以下內容：
