well that screenshot doesn't show you using adriane shell or opensh. Before running the commands you can check if you have enough capabilities in your shell with:

RM696-21-3_PR_001:~# accli -I |grep tcb-sign
aegis-enabler::tcb-sign
RM696-21-3_PR_001:~#

If grep doesn't return that line, then you need to devel-su into opensh, or gain privileges with adriane sh.
