+```
+No usable sandbox! Update your kernel or see https://chromium.googlesource.com/chromium/src/+/main/docs/linux/suid_sandbox_development.md for more information on developing with the SUID sandbox. If you want to live dangerously and need an immediate workaround, you can try using --no-sandbox.
+```
+
+You can work around this using `--chrome-args`:
+```bash
+wormhole-cli --chrome-args="--no-sandbox" <your file>
