What example, what options? src/snes/examples/tutorials/ex19.c in fact almost all examples should run fine on one process without MPI. It looks like what you are running has hardwired in it something that requires more than 1 process which is very rare for PETSc examples. We need to see all the error output (not just one tiny fragment) to see what is wrong; too much information is always better than too little in debugging.
