It looks like Sage installed via conda-forge, and
ImportError: /home/sage/.conda/envs/sage/lib/python3.6/site-packages/sage/matrix/../../../../libgd.so.3: undefined symbol: libiconv seems to indicate that libiconv is missing in the environment. I don't know much about conda, but it seems that you need to run something like conda install -c conda-forge libiconv and try running sage again...
