• Your Windows build number: 10.0.16299.214

• What you're doing and what's happening:

root@PC-MING:~/WinLinks/M/tmp/sshdiag# strace -ff -v -o sshdiag -r service ssh --full-restart
 * Stopping OpenBSD Secure Shell server sshd                                                                              [ OK ]

• What's wrong / what should be happening instead: sshd service could not be started.

• Strace of the failing command, if applicable:

This also happens to other packages such as apt while downloading a new package, or apache2 while starting the service.

I've already read issues such as #2142 but with no luck, and I can also rule out the impact from antivirus software or IPv6 since the IPv6/Anti-Virus was enabled and the whole system was running without any problem before this issue happens.

Here's a copy of my ifconfig:

#508 has been the de-facto landing zone for Error IN6_IS_ADDR_V4MAPPED, but it is closed. The remaining open one (by pure chance) is #2734. Duping there.
