This bug was fixed in the package systemd - 237-3ubuntu10.2
---------------
systemd (237-3ubuntu10.2) bionic; urgency=medium
* logind: backport v238/v239 fixes for handling DRM devices.
These changes introduce all the fixes that correct handling of open fd's
related to the DRM devices, as used by for example NVIDIA GPUs. This
backport
includes some refactoring, corrections, and comment updates. This to insure
that correct history is preserved, code comments match reality, and to ease
backporting logind fixes in the future SRUs. (LP: #1777099)
* Disable dh_installinit generation of tmpfiles for the systemd package.
Replace with a manual safe call to systemd-tmpfiles which will process any
updates to the tmpfiles shipped by systemd package, taking into account any
overrides shipped by other packages, sysadmin, or specified in the runtime
directories. (LP: #1748147)

[ Dimitri John Ledkov ]
* hwdb: Fix wlan/rfkill keycode on Dell systems. (LP: #1762385)
* Cherrypick upstream fix for corrected detection of Virtualbox & Xen.
(LP: #1768104)
* Further improve captive portal workarounds.
Retry any NXDOMAIN results with lower feature levels, instead of just those
with 'secure' in the domain name. (LP: #1766969)
[ Michael Biebl ]
* Add dependencies of libsystemd-shared to Pre-Depends.
This is necessary so systemctl is functional at all times during a
dist-upgrade. (Closes: #897986) (LP: #1771791)
[ Mario Limonciello ]
* Fix hibernate disk offsets.
Configure resume offset via sysfs, to enable resume from a swapfile.

Bug description:
[Impact]
* More captive portals have been discovered that do not handle DNS requests
with D0 set.
* Thus extend previous aruba-networks fix from
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1727237 by retrying all
NXDOMAIN results with lower feature levels just in case.
[Test Case]
* systemd-resolved something-nonexistant.ubuntu.com
* monitor the logs, and check that the transaction has been downgraded
multiple times and tried at least once at a feature level below D0. There
should be a downgrade message in the log.
* Note, it will be cached, thus one may need to call $ systemd-resolved
--flush-caches
[Regression Potential]
* Legitimate NXDOMAIN queries will now take longer, as they will be
retried multiple times with different features sets until an answer is
found. At that point the query will be cached and will return quickly.
This is needed to work-around bad captive portals that do not support
dns queries with D0. Post-captive portal, the feature level can
usually be cranked back up and it does after a grace period.
[Other Info]
* Original bug report
I was asked to create a new bug for this in
https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1727237 as it
seems to be a different issue.
I have installed the nightly image of Kubuntu Bionic from 25th of
April.
There systemd is in version 237-3ubuntu10.
When connecting to the wifi hotspot in my hotel (Quality Hotel
Augsburg) I cannot open the hotspot landing page that should give me
access to the WIFI. With Windows and on an Iphone it's working.
For the following distributions I can confirm it not working:
Kubuntu 17.10
Kubuntu 18.04 (nightly image 25th of April 2018)
The logs were taken on 18.04.
Workaround:
sudo systemctl disable systemd-resolved.service
sudo service systemd-resolved stop
sudo rm /etc/resolv.conf
sudo nano /etc/NetworkManager/NetworkManager.conf
  >> add "dns=default" under [main]
sudo service network-manager restart
Then I can connect to the WIFI and I see the login page in Firefox.
To capture some data I did the following:
 - connect to Hotspot
 - enter golem.de
Case 1: Fresh default Kubuntu install
With a default Kubuntu install it does not work. I can connect to the WIFI
and get IP and DNS from DHCP but I cannot resolve any hostname. When trying to
open the router ip directly in the browser it forwards to hotsplots.de which
cannot be resolved.
Case 2: With aforementioned Workaround
I connect to the wifi, I open firefox and the login page shows up (if I
havent been connected yet. In the capture I already was able to connect to the
hotspot which allows immediately to connect to the webpage)
PS: I'll be in this hotel till Friday 27th if more information are
required.
