I'm trying to emulate a MIPS binary on my Ubuntu 16.04 x86 system, but I'm not able to. I chroot into the squashfs-root filesystem that I got from binwalking the firmware image.

My system info:

Any idea on how to resolve this? All the resources that I was able to find online have something to do with .so files causing the error.
