如果我正在运行 Beta 版,如何升级到发布版本 16.04?

如果我正在运行 Beta 版,如何升级到发布版本 16.04?

操作系统:Ubuntu Xenial Xerus(开发分支)(GNU/Linux 4.4.0-18-generic x86_64)

您好,我已安装并配置了 16.04 的最终测试版,我看到它显示(development branch)。正式版发布后,当我运行以下任一程序时,它会自动更新到生产发布版本吗?

  • apt-get upgrade
  • do-release-upgrade
  • apt-get dist-upgrade

我是否需要修改某些内容才能开始从产品/发布版本中提取分支什么时候正式发布?

该盒子稳定且运行良好。我是否可以保留当前配置,还是需要完全重新安装?

答案1

一旦 16.04 发布,请运行:

sudo apt-get update
sudo apt-get dist-upgrade

可以解决问题,不需要do-release-upgrade(这实际上不会产生任何效果,因为您已经在使用 16.04,因此没有地方可以升级)。应该不需要更改任何其他内容,任何需要更改的内容都应该会自动为您完成。

顺便提一下,sudo apt-get dist-upgrade除了上述所有sudo apt-get upgrade功能外,还会升级很多东西,因此不需要同时运行两者,该dist-upgrade选项涵盖了它们,如手册页中所述(man apt-get):

dist-upgrade in addition to performing the function of upgrade,
           also intelligently handles changing dependencies with new versions
           of packages; apt-get has a "smart" conflict resolution system, and
           it will attempt to upgrade the most important packages at the
           expense of less important ones if necessary. The dist-upgrade
           command may therefore remove some packages. The
           /etc/apt/sources.list file contains a list of locations from which
           to retrieve desired package files. See also apt_preferences(5) for
           a mechanism for overriding the general settings for individual
           packages.
