fet 5.39.0-2 (amd64 binary) in ubuntu eoan

 FET is a program for automatically generating the timetable of a school,
 high-school or university.
 .
 Usually, FET is able to solve a complicated timetable in maximum 5-20 minutes.
 For simpler timetables, it may take a shorter time, under 5 minutes (in some
 cases, a matter of seconds). For extremely difficult timetables, it may take
 a longer time, a matter of hours.
