Thanks Johan and Bas. I will stick to same version for ubuntugis also.
As you all know 6S was not included because of having no license.
What will be a possible options that allows to have this activated in OTB?
Could we package it as new libsixs package or something ?
Here the problem is again with license
Note that we are using a generated C source of original 6S code which was in fortran. I can check which tool has been used in past for generating c source from fortran by OTB.
As we are unable to provide an mail exchange from 6S authors regarding its usage in OTB and now developers tried contacting the authors again. Still there is zero response. We might be able to produce an exception or may be never.
