Why a KeyboardInterrupt is raised when simulating a linksys firmware?

[cloud0606]

I didn't do anything, but I got KeyboardInterrupt

$ sudo ./run.sh -c linksys ./FW_WRT32X_1.0.180404.58.img
[*] FirmAE_dataset/linksys_latest/FW_WRT32X_1.0.180404.58.img emulation start!!!

KeyboardInterrupt

During handling of the above exception, another exception occurred:

I can use binwalk alone to extract firmware

$ binwalk -e  ./FW_WRT32X_1.0.180404.58.img

I don't know which step went wrong, Is it my problem with binwalk installation?

Thank you for your issue!

The old version binwalk cannot correctly extract files in FW_WRT32X_1.0.180404.58.img firmware.

I missed pulling the latest binwalk when executing install.sh.

Now, install.sh script will install latest binwalk (53701af3615d0caa015e41ed2d5804edee7ff3c7), and extractor.py will extract filesystem correctly from FW_WRT32X_1.0.180404.58.img firmware.

Thank you!
