Thanks for this step by step guide! I've noticed the same errors updating to 2.7.2. The icu build matched the version of the error, however, still generated similar error messages. Upon reinstalling (fingers crossed) I no longer see those errors, and my DNS lookup feature that was previously broken, now works! Thank you again!
