bash on windows可以升級為16.04嗎?

02-05

我升級失敗了
$ sudo do-release-upgrade [screen is terminating]

這個問題我Google了半天，終於成功升級。

查證中發現，下面這樣用 Ubuntu 的自動升級在 Bash on Windows 會失敗的：

sudo aptitude install update-manager-core sudo do-release-upgrade

因此需要用類似Debian的升級方法，我主要參考的是 Upgrade Ubuntu on Windows from 14.04 to 16.04 : windowsinsiders

下面我整理一下各個步驟：

1. 獲取全局root許可權

$ sudo -s # 然後輸入密碼

2. 把所有包升級至 14.04 (trusty) 的最新版

$ aptitude update $ aptitude full-upgrade -y

3. 更改更新源為 16.04 (xenial)

# 方法一：修改初始的更新源文件 # 備份初始的源文件為sources.list.ORIG，將sources.list里的"trusty"全替換為"xenial"。 $ sed -i.ORIG s/trusty/xenial/g /etc/apt/sources.list

# 方法二（推薦）：把更新源直接改為國內的阿里雲Ubuntu(xenial)鏡像，這樣會很快 # 編輯更新源文件 $ vim /etc/apt/sources.list # 清空文件後粘貼如以下代碼： deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse # :wq 保存退出

4. 備份並新建空文件夾 /etc/apt/sources.list.d/

註：bash剛裝好時這個文件夾是空的，若如此可跳過這一步

$ mv /etc/apt/sources.list.d/ /etc/apt/sources.list.d.ORIG/ $ mkdir /etc/apt/sources.list.d/

5. 升級至 16.04 (xenial)

$ aptitude update $ aptitude safe-upgrade -y # 注1：升級過程中會提示你重啟服務（restart services），選yes # 注2：還會出現文件衝突，保留當前版本（current version）即可，輸入N

6. 把所有包升級至 16.04 (xenial) 的最新版，並重裝丟失的aptitude包，最後清理無用包

$ apt-get dist-upgrade $ apt-get install aptitude $ apt-get autoremove

7. 至此已經順利升級至 16.04 (xenial) 了，但你會發現像原來那樣使用sudo命令會報錯：

# 重啟Bash，在非root許可權下測試 $ sudo apt-get update sudo: no tty present and no askpass program specified

# 此後用sudo只能這麼用： $ sudo -S apt-get update

如果你裝錯了，或者想退回 Ubuntu 14.04 (trusty)，把Linux子系統卸載重裝即可：

&> lxrun /uninstall /full /y &> lxrun /install

最後，引用一句話：

So when will the newer Ubuntu 16.04 LTS release be available? In a recent comment, Microsoft』s Rich Turner explained: 「We have to add some additional capabilities to make it work well, but we are looking at 16.04 support for a future release.」

微軟自認為這個 Bash on Ubuntu on Windows 還不夠穩定，所以暫不支持官方升級，這樣強行升級會有什麼後果，那就不好說了，大家湊合用吧。

現在別急著亂動，MS官方已經確認，明年年初的Win10RS2將會讓WSL內置的Ubuntu升級到16.04LTS

Build 14936


For general Windows information on build 14936 visit the Windows Blog.

To track or report an issue visit our Github page.

Note: WSL will install Ubuntu version 16.04 (Xenial) instead of Ubuntu 14.04 (Trusty) in an upcoming release. This change will apply to Insiders installing new instances (lxrun.exe /install or first run of bash.exe). Existing instances with Trusty will not be upgraded automatically. Users can upgrade their Trusty image to Xenial using the do-release-upgrade command.

Bash on Ubuntu on Windows

Windows10 1703版本已經可以通過

sudo do-release-upgrade

進行升級了.升級的過程也比較簡單.

發現一個神器 GitHub - RoliSoft/WSL-Distribution-Switcher: Scripts to replace the distribution behind Windows Subsystem for Linux with any other Linux distribution published on Docker Hub.

打開zsh後遇到和上一個方法相同的問題(作死重新試過以後發現沒有問題了)

Ok, so heres the final state of things on my end. From a brand new install of Bash on build 14379, ran the following: sudo su apt‐get update apt‐get upgrade apt‐get dist‐upgrade apt‐get autoremove sudo do‐release‐upgrade ‐f DistUpgradeViewNonInteractive ‐d As noted, it still gets stuck at a Y/N prompt. Pressed Ctrl+C and ran: echo yourpasswordhere | sudo ‐S dpkg ‐‐configure ‐a apt‐get update apt‐get upgrade apt‐get dist‐upgrade apt‐get autoremove

--------失敗了------------

# Upgrade all the packages to the latest versions aptitude update aptitude full-upgrade -y


# Update our sources, save the original as /etc/apt/sources.list.ORIG

# This step is REQUIRED, otherwise the instructions below will not upgrade a

# single package.

sed -i.ORIG s/trusty/xenial/g /etc/apt/sources.list
# Backup the /etc/apt/sources.list.d/ folder and create an empty one.

# This will disable all Third Party/Launchpad PPA repositories.

# These repositories can be re-enabled after a successful upgrade.

mv /etc/apt/sources.list.d/ /etc/apt/sources.list.d.ORIG/

mkdir /etc/apt/sources.list.d/
# Upgrade your box--the easy part.

aptitude update

aptitude safe-upgrade -y

# Now for the scary one--see below. apt-get dist-upgrade

Windows 10 Preview Build 14936 以後的的版本已經內置16.04，我上個月自動升級後發現內核升級了。

還是有不少包有兼容性問題，我果斷還是開hyper v裝了個ubuntu server1604來測試部署環境
