The ID address had no effect. As I said, Files seemed to think that there is a problem with the smb protocol itself, because as soon as I typed smb:, the text became red.
Anyway, I clicked one of your links and found that it was using “gvfs-smb”. I checked it and it was not installed. I installed it and restarted Files; no change. I rebooted the system, and then smb worked. In short, I think this is all caused by the absence of “gvfs-smb” in the “minimal version”. I wish Files were a little bit smarter and told the user to install it (or automatically install it) instead of only turning the address red, when it could not use smb.
