Hmm yeah, now it's complaining about libm.so.5 missing...
That should be part of libc 5.3, which would be hell to install side-by-side whichever version you currently have. Not a rabbit-hole to go down lightly. Maybe an old (2011-ish) Linux distro in a VM would be the way to go. If you want the effort. (I obviously don't feel like pursuing it myself).
The few files I have are on a dir on my desktop, the superuser password is passw0rd. Thanks!
