linux误删libc-bin出现dpkg: warning: ‘ldconfig’ not found in PATH or not executable

用apt安装任何软件都会报如下错误
Preconfiguring packages …
dpkg: warning: ‘ldconfig’ not found in PATH or not executable
dpkg: error: 1 expected program not found in PATH or not executable
Note: root’s PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin

E: Sub-process /usr/bin/dpkg returned an error code (2)

这是因为找不到/sbin，目录下的ldconfig了。

解决：

sudo apt-get download libc-bin
dpkg -x libc-bin*.deb unpackdir/
sudo cp unpackdir/sbin/ldconfig /sbin/
sudo apt-get install --reinstall libc-bin
sudo apt-get -f install
