我首先尝试安装httping，以便可以 ping 网站。我收到此错误：
ERROR: File not found: //usr/local/lib/ipkg/lists/whiterussian
You probably want to run `ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/non-free

/bin/ipkg: line 1184: can't open /jffs//usr/local/lib/ipkg/status: no such file
因此，我尝试运行ipkg update。它花费了不到四分之一秒的时间完成（这令人惊讶），然后我ipkg install httping再次运行，但出现同样的问题。然后，我决定运行ipkg list，结果如下：
ERROR: File not found: //usr/local/lib/ipkg/lists/whiterussian
You probably want to run `ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/non-free
You probably want to run `ipkg update'
ERROR: File not found: //usr/local/lib/ipkg/lists/backports
You probably want to run `ipkg update'
那么，我该如何解决这个问题？
注意：我有一台 Netgear WNDR4300。
更新：我尝试运行bash和/bin/bash，结果得到-sh: /bin/bash: not found。这里发生了一些非常奇怪的事情。
