Invalid cert warnings with Chrome 64 on Ubuntu 16.04.03 with Burp version 1.7.32

I regenerated the Burp certificate, extracted it (cacert.der) from the above-mentioned chrome using "http://burp/cert", copied the cert to /usr/share/ca-certificates/extra, used openssl to translate the DER form to PEM form to file cacert.crt. Then ran dpkg-reconfigure ca-certificates to import the new certificate. When bringing up a secure site in the browser through the command line to set the proxy, I still get the certificate warnings, showing that it has the portswigger certificate. Additionally, chrome complains to standard error out "ERROR:cert_verify_proc_nss.cc(922) CERT_PKIXVerifyCert for translate.googleapis.com failed err=8172". I also went so far as to install the cacert.pm in /etc/ssl/certs with the same result. There must be something that i am missing.

Have you tried opening Chrome settings > searching for "Certificate" > using the Import function?

I am thinking that this is a Chrome issue, as I was able to get the proxy to work properly with Firefox 58.

We've tested this version of Chrome with our certificate and haven't encountered the same issue.
