Comment 12 for bug 1685900

How does that service changed between these versions?

$ git diff v232..v233 src/resolve/ | diffstat
36 files changed, 950 insertions(+), 284 deletions(-)

And that's just resolved specific code, but there are a lot more changes in shared code.

You have not provided any system logs, error messages from the daemon, or steps to reproduce the problem.

If you are not going to share systemd-journal logs of the failing systemd-resolved.service there is nothing I can do to fix the problem you have encountered.

Are you sure you are using systemd-resolved now? Is the service running and does resolv.conf point at it?
