Description

I’m running into an issue on GitHub Actions where jobs using Ubuntu 22.04 fail to load the dynamic library librive_native.so, even after running dart run rive_native:setup --verbose --clean --platform linux.

Ubuntu 24.04 does not appear to have this issue, and the tests pass there without any problems.

The failure was first identified on my company’s self-hosted custom runners, which are based on Ubuntu 22.04. Since those runners cannot be upgraded for now, this issue is currently blocking us.

I’m aware that there is also a --build option, although I haven’t tested it yet. Since it requires additional system packages and tooling to be installed, I would prefer to avoid that route unless it is strictly necessary. Using the existing prebuilt binaries would be preferable.

I’ve attached screenshots from the runs available in my public repo, which I created specifically to reproduce the issue.
