The testing version 1.44.2-3 is broken too.

This is because /usr/libexec/nm-dhcp-helper exists in
1.44.2-3 and 1.44.2-4, but not in 1.44.2-1.

I suspect that nm-dhcp-helper has been added because it is now needed.
But it doesn't work due to the "Permission denied".

I've attached more journalctl output, in case it is needed.
