我的 texlive 安装似乎无法正常工作，但方式很奇怪。以下是从日志生成的。我正在从 安装install-tl-20170413到 Ubuntu 16.04。我运行的具体命令是sudo ./install-tl。
Can't exec "kpsewhich": No such file or directory at /usr/local/texlive/2016/bin/x86_64-linux/updmap line 22.

它抱怨找不到的第一部分kpsewhich有点可疑，因为该文件存在：
$ ls -l /usr/local/texlive/2016/bin/x86_64-linux/kpsewhich
-rwxr-xr-x 1 root root 83424 Apr 7 2016 /usr/local/texlive/2016/bin/x86_64-linux/kpsewhich
有办法恢复安装吗？我刚刚升级了我的 Ubuntu，因为今天早些时候的尝试提到了“共享库问题”。该消息已经消失了。
