Behind Corp Proxy

let’s assume you’re behing a Corp Proxy which enforce TLS Inspection, you don’t have the Proxy Cert and you want to Upgrade your Boxes …

… and of course, you do this in the LAB and for Research only and not your Productiv Environment!

TLS Inspection enabled

apt-get upate
W: Failed to fetch  Certificate verification failed: The certificate is NOT trusted.
The certificate issuer is unknown.  Could not handshake: Error in the certificate verification. [IP: xx.xx.xx.xx yyyy]

Disable TLS Check

touch /etc/apt/apt.conf.d/99verify-peer.conf
echo >>/etc/apt/apt.conf.d/99verify-peer.conf "Acquire { https::Verify-Peer false }"


apt-get update
apt-get upgrade
