If you see the following error when trying to log in using connectd_installer:
The login security certificate is not valid. This can be caused
by your system date being incorrect. Your system date is:
Fri Nov 8 23:48:36 CET 2019
most likely you do not have the ca-certificates package installed on your device.
You can either install the ca-certificates package (recommended) or, to skip certificate checking, edit
and change the line:
CURL_OPTS="-s -S -X"
CURL_OPTS="-k -s -S -X"
