Identifying golang deadlock. 5 philosophers problem

I am getting fatal error: all goroutines are asleep - deadlock! on the line wg.Wait() It happens for about ~30% of the runs, the rest are finished with no error. I guess I am not using WaitGroup the wrong way, but not sure what am I doing wrong. Maybe someone can help me identify my bug? Thanks!

package main

import (
    "fmt"
    "math/rand"
    "sync"
    "time"

const (
    numOfPhilosophers = 5
    numOfMeals = 3
    maxEaters = 2
)

var doOnce sync.Once

func main() {
    chopsticks := make([]sync.Mutex, 5)
    permissionChannel := make(chan bool)
    finishEating := make(chan bool)
    go permissionFromHost(permissionChannel,finishEating)
    var wg sync.WaitGroup
    wg.Add(numOfPhilosophers)
    for i:=1 ; i<=numOfPhilosophers ; i++ {
        go eat(i, chopsticks[i-1], chopsticks[i%numOfPhilosophers], &wg, permissionChannel, finishEating)
    }
    wg.Wait()
}

func eat(philosopherId int, left sync.Mutex, right sync.Mutex, wg *sync.WaitGroup, permissionChannel <-chan bool, finishEatingChannel chan<- bool) {
    defer wg.Done()
    for i:=1 ; i<=numOfMeals ; i++ {
        //lock chopsticks in random order
        if RandBool() {
            left.Lock()
