Hi thanks for your help. Unfortunately I get this error:
ERROR: cannot verify letsencrypt.org's certificate, issued by `/C=US/O=IdenTrust/OU=TrustID Server/CN=TrustID Server CA A52':
Unable to locally verify the issuer's authority.
To connect to letsencrypt.org insecurely, use `--no-check-certificate'.
So I used command: wget --no-check-certificate letsencryptauthorityx1.pem https://letsencrypt.org/certs/letsencry … rityx1.pem
That worked. Then I used your command: ln -s letsencryptauthorityx1.pem "$(openssl x509 -hash -noout -in letsencryptauthorityx1.pem).0"
That resulted in following error:
-hash -noout -in letsencryptauthorityx1.pem).0"
unable to load certificate

What is wrong / an be a solution?
