尝试使用 下载 SWI-Prologsudo apt-get install swi-prolog时，出现一系列错误：
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:
libpython3-dev : Depends: libpython3.5-dev (>= 3.5.1-2~) but it is not installable
python3.5-dev : Depends: python3.5 (= 3.5.2-2ubuntu0~16.04.4) but 3.5.2-2ubuntu0~16.04.3 is to be
installed

Depends: libpython3.5 (= 3.5.2-2ubuntu0~16.04.4) but 3.5.2-2ubuntu0~16.04.3 is to be

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我确实尝试apt-get -f install过，这引发了错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done

sudo apt-get update使用or进行完整更新时，我也遇到了同样的问题upgrade。我该如何解决这些错误？
