Description: After updating to systemd233.75, I get an error when I try to use systemd-resolved. I ran into the issue trying to start openvpn, but I found that basically any command using systemd-resolve gives an error. Here are a few commands I ran:

20:19 ~ $ systemd-resolve status
status: resolve call failed: Unit dbus-org.freedesktop.resolve1.service not found.
20:20 ~ $ systemd-resolve yahoo.com
yahoo.com: resolve call failed: Unit dbus-org.freedesktop.resolve1.service not found.

Jul 10 20:20:10 leaf dbus[406]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.resolve1.service': Unit dbus-org.freedesktop.resolve1.service not found.


This happens on both my laptop and desktop running Arch. I downgraded both systems and then systemd-resolve started to work as expected on both systems.

I noticed that in the package systemd 233.75-3, the directory /etc/systemd/system/ is empty.
In the systemd 233-7 package, /etc/systemd/system/ contains several files ending in .service, including dbus-org.freedesktop.resolve1.service. I'm guessing that empty directory is the issue.


Additional info:
* package version(s)
233.75-3 - bad
233-7 - no issue
* config and/or log files etc.


Steps to reproduce:
Update systemd to 233.75-3. Run "systemd-resolve --status".
This task depends upon

I think I have figured out how to fix this issue. On an affected machine, I copied dbus-org.freedesktop.resolve1.service from an older version of the systemd package into /etc/systemd/system/. Then systemd-resolve started to work as expected.

Update: maybe that should actually be a symlink that goes in /etc/systemd/system/ instead of an actual file. Running this command just fixed it on my desktop after updating systemd to 233.75-3:


/etc/systemd/system $
/etc/systemd/system $ sudo ln -s /usr/lib/systemd/system/systemd-resolved.service dbus-org.freedesktop.resolve1.service
/etc/systemd/system $

In /usr/lib/systemd/system I found the following symlinks:

dbus-org.freedesktop.hostname1.service -> systemd-hostnamed.service
dbus-org.freedesktop.import1.service -> systemd-importd.service
dbus-org.freedesktop.locale1.service -> systemd-localed.service
dbus-org.freedesktop.login1.service -> systemd-logind.service
dbus-org.freedesktop.machine1.service -> systemd-machined.service
dbus-org.freedesktop.network1.service -> systemd-networkd.service
dbus-org.freedesktop.timedate1.service -> systemd-timedated.service

So apart from resolve1 being missing, it seems to me that the symlink should not be added to /etc/systemd/system as described above, but rather /usr/lib/systemd/system.

I ran pacman -Fs dbus-org.freedesktop.network1.service before syncing the file database with the following result:
core/systemd 233-7
usr/lib/systemd/system/dbus-org.freedesktop.network1.service

However, after running pacman -Fy I get no result anymore.
In systemd 234.11-1 (testing), the file is still missing.

This means that somewhere between systemd 233-7 and 233.75-3 the file went missing.

Upstream moved the file from /usr to /etc, we remove it when building the package.
This file is supposed to be linked by systemctl when systemd-resolved.service is enabled. Package systemd 233.75-3 has code in install script to reenable systemd-resolved.service (and hence recreate the symlink) when required.
