Failed to upgrade v2.0



I am trying to upgrade from v2 but the request to get the releases seems to be failing. Below is the full stack trace, but it seems to be a connection error. Any thoughts on why this would be?

Traceback (most recent call last):
File “bin/upgrade”, line 251, in

release = get_release(channel)
File “bin/upgrade”, line 95, in get_release

First, you should try:

curl -D - -s -o /dev/null ""

The response would be like the following if there are no problems.

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Date: Sat, 17 Nov 2018 04:52:19 GMT
ETag: W/"d42-h+2wW93sHAJU5IlOKRk4Cw"
X-Powered-By: Express
Content-Length: 3394
Connection: keep-alive

Otherwise, you should check you can access outgoing from your host.

If you were able to get the response with 200 OK, how about running the following command?

python -c "import requests; print requests.get('')"
