I'm not sure if there may be other issues here too, but did you update-grub before rebooting? If not, does /etc/hosts currently contain localhost ::1 ? If so, it seems ipv6 is still disabled while localhost is associated with an ipv6 address, which may have some bearing according to these [not entirely pertinent] sources: https://stackoverflow.com/questions/67173756/socket-address-family-not-supported-by-protocol https://unix.stackexchange.com/questions/407663/ipv6-socket-creation-failed-address-family-not-supported-by-protocol https://github.com/netdata/netdata/issues/1282 Hope that helps.
