Just a follow up here. Turns out the default configuration (shown
above) is limited to a 30 minute timeout, which isn't enough to get
all the dependencies installed and QGIS built, let alone leaving time
for debugging ;)

After some discussion with Travis staff (who have been fantastic, I've
got to say!), there's a workaround. By changing "quiet": true to
"quiet": false, the interactive session is subject to the normal 90(+)
minute timeout. The side effect is that all the commands entered are
visible to anyone looking at the Travis log, so be careful not to do
this with any sensitive information.

The command is full is:

#! /usr/bin/env bash
  curl -s -X POST \
   -H "Content-Type: application/json" \
   -H "Accept: application/json" \
   -H "Travis-API-Version: 3" \
   -H "Authorization: token <TOKEN>" \
   -d '{ "quiet": false }' \
