例如，当我输入时apt-get install tor我得到：
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libpcap0.8-dev : Depends: libpcap0.8 (= 1.3.0-1) but 1.6.2-2 is to be installed
libsqlite3-dev : Depends: libsqlite3-0 (= 3.7.16.2-1~bpo70+1) but 3.8.7.1-1+deb8u1 is to be installed
tor : Depends: libseccomp2 (>= 0.0.0~20120605) but it is not going to be installed
Recommends: tor-geoipdb but it is not going to be installed
Recommends: torsocks but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
即使当我输入时apt-get -f install tor我也会得到同样的错误！
