Failed to flush caches: Unit dbus-org.freedesktop.resolve1.service not found using sshuttle about sshuttle

[ret7020]

Kali Linux using systemd-resolved and Network Manager.
You can try to run systemd-resolved.service (systemctl start systemd-resolved.service).
I have the same warning "Failed to flush caches: Unit dbus-org.freedesktop.resolve1.service not found.", but it does not interfere with sshuttle work without problems

sshuttle tries to flush the DNS cache that systemd-resolvd uses. If we fail to do so (maybe because systemd-resolvd isn't used on your system), then sshuttle prints that message and continues running.

If DNS entries are being cached somewhere on your system, then the cache was not flushed and you may experience trouble if a hostname was supposed to resolve differently with sshuttle running: It would resolve to the hostname that it did before sshuttle started running. Besides that, sshuttle should otherwise work.
