I don't know what is causing the error on your side. Hope this helps:

These are my settings for RODBC 1.3-10 to connect to MSSQL Server 2012. I am also on ubuntu and this works for me. I think I installed the RODBC package from the Ubuntu repos:

apt-cache policy r-cran-rodbc
r-cran-rodbc:
  Installed: 1.3-10-1
  Candidate: 1.3-10-1
  Version table:
 *** 1.3-10-1 0
