软件更新程序错误

Question

我在 Ubuntu 16.04 中设置以太网连接时遇到了严重问题，因此我想进行软件更新，并这样做了。它中途停止了，出现了这个黑屏：https://i.stack.imgur.com/F0R0z.png

perl: warning: setting locale failed. 
perl: warning: Please check that your locale settings: 
        LANGUAGE = (unset), 
        LC ALL = (unset), 
        LANG = "en IN.ISO8859-1"
    are supported and installed on your system. 
perl: warning: Falling back to the standard locale ("C").

编辑 1：我遵循了 Ken Sharp 在评论部分所说的话：现在看起来这样对吗？
