  How can smb1 be installed? libsmbclient.so.0 can work using different versions of SMB protocol depending on it's version (but it's API and ABI are stable). It chooses protocol version by itself. SMB2 and SMB3 currently cannot be discovered via NetBIOS by samba, because only smb1 supports netbios discovery, but samba developers have some plans to send DCERPC over smb2/smb3 connections (I don;t know what is DCERPC, but that's what samba developer told me).
  
  Before samba 4.7, NT1 (smb1) the maximum protocol in libsmbclient, if I'm not mistaken; then they made it possible to connect to smb3 servers without manually rising client max protocol, this and/or badlock fixes broke network discovery via smb://, for now, the only way is to manually force NT1 whaen needed, it's what this patch does.
