如何解决 Windows 10 Spring Creators Update 上 Ubuntu 中的运行级别错误？

Question

当apt-get dist-upgrade在 Windows 10 Spring Creators Update (RS4) 上运行 Ubuntu 18.04 时，我收到此错误：

Preparing to unpack .../ebtables_2.0.10.4-3.5ubuntu2.18.04.1_amd64.deb ...
invoke-rc.d: could not determine current runlevel
 * Error: insufficient privileges to access the ebtables rulesets.
invoke-rc.d: initscript ebtables, action "stop" failed.
dpkg: warning: old ebtables package pre-removal script subprocess returned error exit status 1
dpkg: trying script from the new package instead ...
invoke-rc.d: could not determine current runlevel
 * Error: insufficient privileges to access the ebtables rulesets.
invoke-rc.d: initscript ebtables, action "stop" failed.
dpkg: error processing archive /var/cache/apt/archives/ebtables_2.0.10.4-3.5ubuntu2.18.04.1_amd64.deb (--unpack):
 new ebtables package pre-removal script subprocess returned error exit status 1
update-rc.d: warning: start and stop actions are no longer supported; falling back to defaults
invoke-rc.d: could not determine current runlevel
Errors were encountered while processing:
 /var/cache/apt/archives/ebtables_2.0.10.4-3.5ubuntu2.18.04.1_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

我并不真正关心 ebtables （它似乎是一个默认/内置包），但我不想筛选每个更新的输出以找出除此之外是否还有新错误。

事实证明，WSL 不\xe2\x80\x99t 支持 init/runlevels（这是有道理的，因为它实际上没有正常的 Linux 启动过程），如下所述：\n https://github.com/Microsoft /WSL/issues/1761#issuecomment-393154803

好消息是 Ubuntu Cosmic 中进行了修复，该修复已过滤到 Bionic (18.04) 和 Xenial (16.04)：\n https://github.com/Microsoft/WSL/issues/1761#issuecomment-393652849

如果您以前遇到过此问题，那么现在应该已得到解决。
