我的 Windows 10 机器上运行着 Ubuntu。我正在尝试将 openssl 更新到最新版本。（具体来说，我需要安装 1.1.1m）
这是我迄今为止尝试过的：
admin@mymachine:/mnt/c/Users/me$ sudo apt update && sudo apt install openssl
[sudo] password for admin:

但正如您所看到的，它只是再次设置了 1.1.1f。

这是我的 Ubuntu 版本：
admin@mymachine:/mnt/c/Users/me$ cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.4 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.4 LTS"
VERSION_ID="20.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=focal
UBUNTU_CODENAME=focal
我找到了这篇文章：https://code.luasoftware.com/tutorials/linux/upgrade-openssl-on-ubuntu-20/
但在深入研究之前，我想知道是否还有其他方法可以做到这一点/这是否是适用于 Windows 子系统的方法。
请，谢谢。

与此问题相关的是如何更新 Ubuntu 本身？
我尝试过这个：
admin@mymachine:/mnt/c/Users/me$ 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 development release
set Prompt=normal in /etc/update-manager/release-upgrades.
但我不清楚开发版本和非 LTS 开发版本之间有什么区别。谷歌搜索，但如果您对这种方法有任何建议，请随时发表评论。
谢谢！
