I changed it to
NoNewPrivileges=No
That's the only thing I can imagine that would be causing that parsing error. Testing now

> torproject's stretch repository [1] does not contain tor_0.3.1.5 yet.

Once TPOs stretch repo contains the latest, this workaround will no longer be needed, correct?

Two things work:

  1. Changing obfs4 execution permission in system_tor apparmor profile

(abstractions/tor) from PUx to ix.

  1. Keeping PUx but removing "NoNewPrivileges" from tor@default

systemd service (/lib/systemd/system)

JasonJAyalaP added a comment to T676: fix obfs4proxy AppArmor issue in Whonix 14.

I commented out the lines in local/system_tor about obfsproxy. This caused obfsproxy to fail. Changing obfsproxy to rix didn't work. But I'm confused at what I'm seeing, and so I'm still looking at it.

Yes. Because the other solution "not use AppArmor for Tor" is not a great one. It worked in Whonix 13, just needs to be fixed for Whonix 14.

To be clear:
Tor ships a broken apparmor profile (for the last 5 years? Suggested nuke of the profile 3 years ago), and we're trying to unbreak obfs4, correct?

Tor's own app armor profile breaks needed features (obs4). The ticket is 4 years old with no progress. Even they complained about needed to resolve or remove it (years ago).

I was trying obfs4proxy in whonix-gateway. I editted the torrc to UseBridges 1 and added the Client Transport line (note, torrc.examples says to add "managed" at the end; https://github.com/Yawning/obfs4 does not). I then added bridges from tpo (bridge obfs4 ip ... ).
Whonixcheck reports WARNING can't connect to bridge REASON=PT_MISSING
PT_Missing is an error from stem: "no pluggable transport was available"
