按照catcaid的说明文档进行安装, 出现下面错误.
首先采用的是“hash sum mismatch” error when doing update 的方法进行list删除的操作, 但是依然会出现问题

user@ubuntu:~$ 后面在一个csdn的博客
Ubuntu apt-get update Hash Sum mismatch解决方法看到关于网络设备的缓存的解决方法.
尝试将/etc/apt/sources.list.d/pgdg.list文件中的"deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main"改为了https的连接
deb https://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main重新更新结果,正常了.

后面按照http://www.catmaid.org/的手册执行
sudo apt-get install python postgresql-10 imagemagick
完全正常
