Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
grep : PreDepends: libpcre3 (>= 1:8.35) but 1:8.30-5 is to be installed

在https://packages.debian.org/jessie/amd64/libpcre3/download可以下载 Debian 软件包，然后手动安装
dpkg --install libpcre3_8.35-3.3_amd64.deb
之后的apt-get install grep作品。
