Yep. Since there isn't any .travis.yml in xud-docker project, it's better to track this issue on bot side.

Ok, closed ExchangeUnion/xud-docker#598

The above fix is not working. One failed Travis build raw log

No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself.

I found the timeout is actually related to tools/push command python helper.py push "$@". So I changed tools/push for debugging (the following script could prevent ARM 10m error).

#!/bin/bash

set -m
set -euo pipefail
set -x

function print_running() {
  while true; do
    echo ">>> RUNNING <<<"
    sleep 3
  done
}

print_running &

cd "$(dirname "$0")" || exit 1
python helper.py push "$@"

Required commands that will prevent 10m error

1. set -x
2. sleep 3 (60 not working)
3. print_running &

Todos:

• [ ] See if I can print_running inside helper.py
• [ ] See why -x is required
