# newrole not working properly

I'm having some issues with the newrole utility (fom the package policycoreutils-newrole Fedora 27), when I'm trying to switch roles, it's not working no matter what role I choose (even tried with user_r that doesn't require any privileges whatsoever), here are some examples:

➜  ~  seinfo -r

Roles: 14
guest_r
nx_server_r
object_r
staff_r
system_r
unconfined_r
user_r
