I'm having this error with curl:

curl -v

* error setting certificate verify locations:
  CAfile: /etc/ssl/certs/ca-certificates.crt

Ignore the network is unreachable... it happens with every https:// url, even if the network is reachable.

I won't install manually the certificates, cause it should get them automatically... ideas?

Fix. I don't know what the problem was, but it was related to the certificates (ca-certificates) package.

It was fixed by adding ca-certificates and run update-ca-certificates

The distro I was using is Alpine LInux, so the commands are:

apk add ca-certificates

In debian alike it should be:

apt-get install ca-certificates
