I got this when trying to clone a repo from github and an IPv6 only host:
[minfrin@bob openwrt]$ git clone https://github.com/openwrt/packages.git Cloning into 'packages'... fatal: unable to access 'https://github.com/openwrt/packages.git/': Couldn't connect to server
caused by this:
[minfrin@bob openwrt]$ host -t AAAA github.com github.com has no AAAA record
When will github make itself available on the IPv6 internet?
