[BobbyRaduloff]

can confirm I get the same error

[Michae1Weiss]

Same error on Debian 12.

This helped:

git submodule update --remote --merge

See: #84 (comment)

[SamuraiDestroy]

It worked

Side mention, that's just a testing side-piece, the binary still builds prior to the tests so you can just grab it from daemon/owl provided you're in the build directory as mentioned in the setup docs.
