Error: SVN unable to connect to 0AD repository

[KKaslana]

Greetings!

 

I would like to download the latest development version of 0AD from its SVN repository. Unfortunately, after I typed in this command

svn co https://svn.wildfiregames.com/public/ps/trunk/ 0ad

as instructed, these errors were displayed and the process terminated.

svn: E170013: Unable to connect to a repository at URL 'https://svn.wildfiregames.com/public/ps/trunk'
svn: E000101: Error running context: Network is unreachable

 

Initially, I suspected that there is a fault with my ISP, so I tried some pings. Given that I could access all websites through my Google Chrome browser, I am confused by these ping results:

ping www.youtube.com

However, even more surprisingly, I was able to ping the German Google server, even though I am currently located in England:

ping www.google.co.de

Moreover, Git clone does work as usual:

Operating System: Arch Linux x86_64

I would appreciate any help or advice that the community can offer, and I can't thank the developers enough for creating such an amazing game for free!

Hey there,

Indeed it's strange. There have been some issues with Spanish ISP in the past months which was a bit strange. They decided to block all wildfiregames.com websites.

Can you try to use the Google dns see if the link works ? If that's the case it means your ISP if not we'll see if we can diagnose it.

IMHO you have a problem with IPv6 addresses.

Try:

ping -4 svn.wildfiregames.com

If it ping work, try:

sudo sysctl -w net.ipv6.conf.all.disable_ipv6=1
sudo sysctl -w net.ipv6.conf.default.disable_ipv6=1

 These two lines did the trick for me:
