Following the workaround from here works, but I feel it's hacky: https://answers.sap.com/questions/13210328/installing-cf-cli-on-ubuntu-20041.html
I can install CF CLI v8 I add --no-check-certificate as below:
wget --no-check-certificate -q -O - https://packages.cloudfoundry.org/debian/cli.cloudfoundry.org.key | sudo apt-key add -

Can you please have a look at the issue anyway?
