任何人都可以帮助我在运行捆绑更新后将兼容的版本错误升级到Rails 4.2到Rails 5.1.4

Bundler找不到与gem“ actionpack”兼容的版本：在Gemfile中：active_link_to（〜> 1.0.0）已解析为1.0.5，具体取决于actionpack

active_model_serializers (~> 0.10.6) was resolved to 0.10.7, which depends on
  actionpack (< 6, >= 4.1)

hamlit-rails (~> 0.2.0) was resolved to 0.2.0, which depends on
  actionpack (>= 4.0.1)

meta-tags (~> 2.4.1) was resolved to 2.4.1, which depends on
  actionpack (< 5.2, >= 3.2.0)

rails (~> 5.1.4) was resolved to 5.1.4, which depends on
  actionpack (= 5.1.4)

ransack (~> 1.6.6) was resolved to 1.6.6, which depends on
  actionpack (>= 3.0)

rspec-rails (~> 3.4.2) was resolved …

有人请帮助我

运行此命令 sudo ufw allowed 'Nginx Full' 后，我无法连接我的服务器。

在 aws 中是否有任何选项可以撤消此更改或其他任何操作
