Yes, this is a captive portal situation on up-to-date 17.10. The captive
portal popup fails with a DNS error looking for
securelogin.arubanetworks.com and then hilarity ensues. Manually editing
/etc/resolv.conf to use one of these DNS servers makes it all work. So
the problem is systemd-resolved which is the default resolv.conf:
~$ cat /etc/resolv.conf
# This file is managed by man:systemd-resolved(8). Do not edit.
#
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
nameserver 127.0.0.53
search invitados
It's all NM:
~$ cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:
version: 2
renderer: NetworkManager
Should /etc/resolv.conf be a symlink?
libnss-resolve is not installed.
systemd-resolve --status shows the two local DNS servers, as above.
~$ systemd-resolve --status | cat -
