You just need to close ipv6 in windows10

i try disable windows ipv6. but i don't know how to disable lo ipv6

@kdwycz - I could not sure this is a solution but... http://www.techunboxed.com/2014/10/how-to-disable-ipv6-in-windows-10.html describes how to disable ipv6 in windows 10.

UPDATE: I found an article Disable IPv6 on Ubuntu Linux and Windows 10.

QUOTE:
To disable IPv6 only for apt-get:

sudoedit /etc/apt/apt.conf.d/99force-ipv4

Put the following contents in it:

Acquire::ForceIPv4 "true";

kdwycz · 2017-05-22T13:14:17Z

@sunjoong thank you, but can't effective

@justid don't work >_<

i start to download recovery Image file to initial my computer

Why should I use Surface instead Mac to coding? Maybe I should wait a year

ycecube · 2017-05-22T15:27:42Z

Check the other issue, maybe you have a similar as I had: #2120 (comment)

kdwycz · 2017-05-23T00:37:15Z

@ycecube Thank you for providing the idea, not applicable for me. But help me find the final answer

Finally, I found a huorong antivirus software, After the uninstall the computer repair

---------------Update--------------
I am giving feedback on this issue in a Chinese forum

justid · 2017-05-23T07:14:40Z

@kdwycz
Please close this issues if everything works fine.

@599281224 uninstall huorong antivirus software

noahzark · 2017-08-09T18:27:36Z

I solved the same problem by Disabling VMware virtual network adapters, and didn't turn off IPV6. Don't know if it would be helpful

evvil · 2017-09-09T07:20:03Z

i found where the problem is. it was caused by the third party softwares such as tencent network manager，antivirus software.
to solve the problem, you need to reset the network in the windows And in my windows 10 build 16278, you can find the reset network button in the setting panel

freeman42x · 2017-11-03T22:51:25Z

@noahzark Disabling VMware virtual network adapters is also what worked for me.

Hello,

Disabling IPV6 or prefer IPV4 on Windows 10 (and restore): https://support.microsoft.com/en-us/help/929852/how-to-disable-ipv6-or-its-components-in-windows

Taken from: https://mobilefish.de/disable-ipv6-ubuntu-linux-and-windows-10 which personal solution did not work for me however.

Microsoft Windows' wizard Prefer IPv4 over IPv6 in prefix policies from the first link worked for me pushing git commits to BitBucket from my Ubuntu Bash console on Windows 10 (https://www.howtogeek.com/249966/how-to-install-and-use-the-linux-bash-shell-on-windows-10/)

Hope this helps.

therealkenc · 2017-11-23T23:17:55Z

Duping down to #508. Thanks for the good info @smilearric

qysnn · 2017-11-27T06:23:41Z

I have tried all the suggested solutions above and nothing works.
But I accidentally find the solution that works for me.

Delete the host file in C:\Windows\System32\drivers\etc.
Repeatedly run the command that caused this error.

For example, I encountered this error when trying to run sudo -H pip install xxxx. After I deleted host file, I run this command 5 times and finally the error is gone and my installation succeeded.
By the way, my Windows version is Windows 10 1709 OS Build 16299.64 and I installed WSL from Microsoft Store.

therealkenc · 2017-11-27T06:55:31Z

Unfortunately "trying all the suggested solutions" is difficult because there are so many dupes for IN6_IS_ADDR_V4MAPPED. For example one suggestion is re-imaging Windows, which will work, but I don't suggest it. It works because it isolates the external factor that is causing the problem.

The TDI filter bypass changes made it into 17046, per #1554 (message). Please give that a try and see if it fixes your case.

Diluka · 2017-12-26T06:30:57Z

I disabled windows firewall and system proxy and this issue still remain.

kingaj12 · 2018-04-06T00:59:33Z

I ran into this issue trying to do conda install. When I switched to sudo /root/anaconda3/bin/conda install the problem went away. No idea why.

xizero00 · 2018-04-06T07:42:25Z

I find the following solution is effective.
I add the following line to the /etc/ssh/sshd_config to force sshd to listen on the ipv4 address.

ListenAddress 0.0.0.0

then restart the sshd service
sudo service ssh restart

kingaj12 · 2018-04-10T01:02:52Z

I had this problem running apt-get. I found this solution to be helpful.
