windows10 更新Ubuntu20.04 LTS的方法步骤

2020年4月23日，今天Windows 上的 Ubuntu 20.04 允许使用 Ubuntu Terminal 并运行 Ubuntu 命令行实用程序，包括 bash、ssh、git、apt 等。它要求 Windows 10 版本 16215.0 或更高版本，支持 ARM64 和 x64 体系结构。要注意的是，该程序在 Windows 10 S 上不受支持。

升级方法：

我这里只针对已有ubuntu的用户

打开ubuntu 或 Windows Terminal，运行命令do-release-upgrade。

frank@LAPTOP-0OCJTGJR:~$ do-release-upgrade
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS develoment release
set Prompt=normal in /etc/update-manager/release-upgrades.

可能会出现上面的报错信息。

打开文件sudo vi /etc/update-manager/release-upgrades

# Default behavior for the release upgrader.

[DEFAULT]
# Default prompting behavior, valid options:
#
# never - Never check for, or allow upgrading to, a new release.
# normal - Check to see if a new release is available. If more than one new
#      release is found, the release upgrader will attempt to upgrade to
#      the supported release that immediately succeeds the
#      currently-running release.
# lts  - Check to see if a new LTS release is available. The upgrader
#      will attempt to upgrade to the first LTS release available after
#      the currently-running one. Note that if this option is used and
#      the currently-running release is not itself an LTS release the
#      upgrader will assume prompt was meant to be normal.
#Prompt=lts
Prompt=normal

默认设置时Prompt=lts，将其改为Prompt=normal.，重新执行命令do-release-upgrade
