Solution to Nope!

Each of the images represents either an architecture (Greek letters) or a Linux error message (Roman letters). In combination, these represent an error code. For example, EDOTDOT_sparc represents 88: http://www.kneuro.net/cgi-bin/lxr/http/source/include/asm-sparc/errno.h?a=sparc#L93

Solving each expression gives a number from 65 to 90, which in turn can be interpreted as ASCII. Doing so gives the phrase PREFIX FOR TIME KILL AND HEAD, which uniquely describes OVER, the answer.
