Ideally yes, but, we don't know that it's an SMB1 problem. When SMB1 is
disabled libsmbc isn't allowed to talk SMB1 with the remote. A remote that only
speaks SMB1 isn't really distinguishable from a remote that has a HTTP server
run on that port for example, they both speak gibberish from libsmbc's POV.
Windows 10 has fundamentally the same problem. 
The best we could do is make the error more descriptive. Patches welcome ;) I
expect we'll also need an entire wiki page or docs page somewhere explaining
the entire mess though. Telling people that this may be because their device
only supports SMB1 isn't that useful without explaining what can be done about
it.

You'll want to talk to your distribution. We haven't changed anything there,
and in fact it's always been libsmbclient's defaults that decided whether or
not SMB1 is supported (it has been off by default for years now though).
