Is certificate expired?

Serg

I tried to install Raspberry Pi runtime that ways:

Add REXYGEN public key:
wget -nc https://download.rexcontrols.com/files/key/rex-debian-key.pub
sudo apt-key add rex-debian-key.pub
For plain Raspberry Pi, run the following commands:
wget -nc https://download.rexcontrols.com/scripts/rex-install-rpi.sh
chmod +x rex-install-rpi.sh
sudo ./rex-install-rpi.sh.

In both case result is:

Resolving download.rexcontrols.com (download.rexcontrols.com)... 217.xxx.xxx.xxx
Connecting to download.rexcontrols.com (download.rexcontrols.com)|217.xxx.xxx.xxx|:xxx... connected.
ERROR: The certificate of ‘download.rexcontrols.com’ is not trusted.
ERROR: The certificate of ‘download.rexcontrols.com’ has expired.

What happend with certificate? What to do?
Thanks for your help.

Hi Serg,

It's possible that the issue you're encountering with the certificate is related to your system being outdated. Have you tried updating your system, set current date and time and then attempting to install the Raspberry Pi runtime again?

Cheers,

I tried to install the missing key in the system manually. He just doesn't exist. Epic fail:
