Note you will need the prereqs (that you already probably have) – openssl & debconf: Most like this command will do to install your root certs: To get the latest list of CA-CERTS, Download the latest ca-certificates file and install it.īut first get root access (or run every command with “sudo” perfix): its truely a bad certificate – you can workaround it with above workarounds (at your own security risk) it should have a good certificate but you dont have the latest ca root certs installed on your box – so follow method below to fix thatĢ. ![]() If a site has a bad certificate it comes down to 1 of 2 things.ġ. # optionally you can put that export in a ~/.bashrc Workaround for git, curl & wget: # wget and curl no check cert Details:Įrror:14090086:SSL routines:SS元_GET_SERVER_CERTIFICATE:certificate verify failed while accessing ĮRROR: The certificate of `is not trusted.ĮRROR: The certificate of `hasn't got a known issuer.
