My image CentOS on Docker not working when it starts the install FreeIPA:
[root@freeipa ~]# ipa-server-install ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR IPv6 stack is enabled in the kernel but there is no interface that has ::1 address assigned. Add ::1 address resolution to 'lo' interface. You might need to enable IPv6 on the interface 'lo' in sysctl.conf. ipa.ipapython.install.cli.install_tool(CompatServerMasterInstall): ERROR The ipa-server-install command failed. See /var/log/ipaserver-install.log for more information [root@freeipa ~]#
I have no idea how to resolve this, please help me.
