Is there any way to disable ipv6 on Debian 10 without breaking networking service ? I added net.ipv6.conf.all.disable_ipv6=1 net.ipv6.conf.default.disable_ipv6=1 net.ipv6.conf.lo.disable_ipv6=1 in /etc/sysctl.conf and is working but networking service failed to activate. I also tried to modify in grub but i get same error networking service failed to start.
