Not trusted certificate error


Does anyone also got a certificate error while installing Cayenne on RaspberryPi3 ?

Hi @frederic.loreaud, welcome to the Cayenne community.

Can you run the command date and let us know if the date/time is set properly on your Pi?

We don’t see this on our end, though you are now the 2nd person I’ve seen mention it so I’ll investigate a bit. That is the correct server and you should feel safe to download from it. You can bypass the check by adding --no-check-certificate to your wget command, ala:

wget --no-check-certificate


Here is what I got.

It seems just one hour in advance.

I’ll test bypassing certificate checker.

Hi guys,
Having a similar issue on my end.
I tried the certificate bypass trick but now I get stuck at the agent install step. The installation literally freezes at the last line here below.
Any idea of what is going wrong?
