It can be started, but it can't be initialized using UI. I didn't test initialization using CLI for this particular case, but most likely the behavior will be the same.
After discussion I reproduced it on ubuntu 16.04 vagrant machine using the following steps:
1) Disable ipv6 in grub configuration in /etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1"
2) sudo update-grub
3) restart the machine
4) install couchbase package
5) try to initialize the node using UI (ipv6 checkbox is unchecked)
6) after pressing "Save and Finish" node doesn't respond
Timofey Barmin: did you test this on a Linux machine by using sysctl to disable the IPv6 stack? Is it the case that the system can't be started on a machine with the IPv6 stack disabled?
