E: 部分索引文件下载失败。如果忽略它们，那将转而使用旧的索引文件。二、错误原因及解决办法
错误原因：
- 导致原因应该是在安装gnutls的时候报错：Libnettle 3.1 was not found，所以安装 了nettle，之后出现的。
- 问题应该是在安装 nettle 的时候，安装到了
/usr/lib64/lib目录下了。update 默认会到系统目录下/usr/lib下寻找依赖关系，软件按系统依赖查找的原因造成。
解决方法：
- 查看 nettle 的路径： find /usr -name 'libnettle*'
$ find /usr -name 'libnettle*'
/usr/lib/x86_64-linux-gnu/libnettle.so.7.0
/usr/lib/x86_64-linux-gnu/libnettle.so.7
/usr/lib64/libnettle.a
/usr/lib64/libnettle.so.6.0
/usr/lib64/libnettle.so.6.4
/usr/lib64/libnettle.so
/usr/lib64/libnettle.so.6
/usr/share/doc/libnettle7- 给 /usr/lib64/libnettle.so.6 建立一个的链接到 /usr/lib/libnettle.so.6
$ sudo ln -s /usr/lib64/libnettle.so.6 /usr/lib/libnettle.so.6- 查看 nettle 的路径： find /usr -name 'libnettle*' ，多了 /usr/lib/libnettle.so.6
$ find /usr -name 'libnettle*'
/usr/lib/x86_64-linux-gnu/libnettle.so.7.0
/usr/lib/x86_64-linux-gnu/libnettle.so.7
/usr/lib/libnettle.so.6
/usr/lib64/libnettle.a
/usr/lib64/libnettle.so.6.0
/usr/lib64/libnettle.so.6.4
/usr/lib64/libnettle.so
/usr/lib64/libnettle.so.6
/usr/share/doc/libnettle7
- 试下 sudo apt-get update 现在报错的提示 libhogweed.so.4 动态链接库错误
