 There might be some other problem in your setup. That ENV-ERROR comes from
 [https://gitweb.torproject.org/pluggable-
 transports/goptlib.git/tree/pt.go?h=0.7#n368 pt.MakeStateDir]. But
 snowflake-client doesn't call pt.MakeStateDir; only snowflake-server does.
 Are you use you copied the client to /usr/bin, and not the server? (Your
 comment:3 refers to /usr/bin/snowflake, but the ticket description refers
 to /usr/bin/snowflake-client.)

 snowflake-server wants access to $TOR_PT_STATE_LOCATION because that's
 where it caches its TLS certificates and keys.

 In any case, the problem is not that the executable was blocked from
 launching, because the error message comes from code inside the pluggable
 transport, not from tor.
