无法将 Ubuntu 16.04 升级到较新的版本

我有一台 HP EliteBook 2540p。我想将我的 Ubuntu 16.04 升级到较新的版本。我发现我需要先升级到 18.04，然后才能升级到 20.04。

我尝试了推荐的程序，使用以下命令更新系统并升级软件和软件包：

sudo apt update && sudo apt upgrade

我想我无法获得我需要的所有更新和升级，而且我不知道问题是什么。

之后我尝试了这个命令来检查可用的版本：

$ sudo do-release-upgrade -c
Checking for a new Ubuntu release
New release '18.04.6 LTS' available.
Run 'do-release-upgrade' to upgrade to it.

它看起来好像正在工作，但是当我尝试升级命令时，它不起作用：

$ sudo do-release-upgrade
Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.

我不知道问题是什么。

答案1

简而言之，您等待的时间太长了，无法轻松有效地完成此事。

16.04 已经超出标准支持范围，这意味着除非您处于扩展安全维护状态，否则不再有更新（静电放电）。您需要先执行更新，然后才能升级到下一个版本，而如果没有 ESM，您就无法做到这一点。因此才出现问题。

您可以注册 ESM，执行系统维护，理论上应该能够顺利升级到 18.04。

但是既然你想使用 20.04，那么版本升级实际上没有任何意义。升级时你不能轻易跳过版本，而且升级总是有可能失败，这取决于你的硬件和系统上已经安装的内容，特别是如果你有任何不是来自 Ubuntu 存储库的软件。版本升级也需要很长时间才能完成。

此时，最好全新安装 20.04。 请记住，LTS 版本附带 5 年的标准支持，如果您不想将来陷入这种困境，请确保及时升级。在新的 LTS 版本不再受支持之前，您有整整三年的时间可以升级到下一个 LTS。

您还可以注册 ubuntu-announce 邮件列表以获取有关新版本和 EOL 公告的电子邮件：

答案2

我尝试从 14.04 进行更新时遇到了很大困难，正当我准备放弃时，我看到了@N0rbert 的评论，这激励我再次尝试。

最终对我有用的步骤是（可能可以优化）

  • sudo apt 更新 && sudo apt 升级
  • sudo apt dist-upgrade
  • sudo 立即重启
  • dpkg --get-selections | awk'$2 ==“deinstall”{print $1}'| xargs sudo apt-get purge -y
  • sudo apt 更新 && sudo apt 升级
  • sudo apt 安装更新管理器核心
  • sudo do-release-升级

我现在成功运行了 16.04.07 LTS。这是个好消息，因为我想要保留的所有重要服务器自定义都完好无损并且正在运行！

** 编辑 **

我意识到我是从 14.04 开始的，它甚至更加破旧，但我的策略也适用于 16.04+

答案3

如果之后

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt autoremove

仍然

Please install all available updates for your release before upgrading.

做

sudo apt list --upgradable

sudo apt remove <listed packages of command above>

例如

sudo apt remove chrome-remote-desktop google-chrome-stable

如果还是不行，尝试：

sudo ua enable esm-infra

如果输出是

To use 'esm-infra' you need an Ubuntu Pro subscription Personal and community subscriptions are available at no charge See https://ubuntu.com/pro

然后注册成为专业人士https://ubuntu.com/pro/dashboard 然后从那里

sudo pro attach <pro token>

现在你可以

sudo apt dist-upgrade

使用新的库。之后

sudo do-release-upgrade

将会做这件事。
