Question

我试图使用以下指令将我的windows ubuntu子系统升级到18.10

但在升级过程中，我得到了以下错误：

 Your system is unable to reach the snap store, please make sure you're connected to the Internet and update any   │
 │ firewall or proxy settings as needed so that you can reach the snap store.                                        │
 │                                                                                                                   │
 │ You can manually check for connectivity by running "snap info lxd"                                                │
 │                                                                                                                   │
 │ Aborting will cause the upgrade to fail and will require it to be re-attempted once snapd is functional on the    │
 │ system.                                                                                                           │
 │                                                                                                                   │
 │ Unable to reach the snap store

我的防火墙是禁用的，我看不出有什么理由，为什么这不会起作用。

我也试图运行snap info lxd，但是

Interacting with snapd is not yet supported on Windows Subsystem for Linux.
This command has been left available for documentation purposes only.

在尝试运行更新时，下面是命令行中的完整消息：

知道吗，我怎么能解决这个问题？子系统有互联网连接，所以我不确定为什么它不能连接到snap商店

Answer 1

这个微软WSL发行完全让它对我有用。从本质上讲，它归结为：

1. 中止do-release-upgrade脚本
2. 重新启动Ubuntu
3. 用：sudo dpkg --force depends -P lxd; sudo dpkg --force depends -P lxd-client删除lxd
4. 用sudo apt upgrade完成

Answer 2

面对同样的问题，我发现了这个问题。

So远，唯一的答案是中止 do-release-upgrade script。我不想要这个

以下是解决办法：

当出现来自lxd的错误消息时，您将得到三个选项，其中一个选项是skip。

在选择跳过之后，出现了以下消息：

Skipping is not allowed when LXD has been initialized                                                                                                                  
LXD appears to have been configured on this system.
Please stop LXD and remove local data in /var/lib/lxd/ if  
you would like to skip installing the LXD snap and migrating the local data.                                    

因此，首先，我打开了另一个Ubuntu窗口并输入：sudo /etc/init.d/lxd stop响应为Stopping Container hypervisor based on LXC: (not running).

然后第二个，我删除了消息中给出的目录：sudo rm -rf /var/lib/lxd

最后一个，我返回到第一个Ubuntu窗口并按返回。再次选择了skip。这一次，安装继续进行。

JBCP方法对我非常有用。差别很小:在运行do-release升级之前，我停止了lxd，并删除了/var/lib/lxd。现在，当系统发展到那个程度时，我就可以跳过了。没有额外的窗户或台阶。非常感谢，不过我不会发现的。
