ERROR: cannot verify dl.google.com's certificate, issued by

Question

I want to install google Chrome in Ubuntu 18.04. I tried:

sudo wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb

But I get an error:

Connecting to dl.google.com (dl.google.com)|216.58.201.46|:443... connected. ERROR: cannot verify dl.google.com's certificate, issued by ‘CN=Google Internet Authority G3,O=Google Trust Services,C=US’:
Unable to locally verify the issuer's authority. To connect to dl.google.com insecurely, use `--no-check-certificate'.

I searched on posts about similar issue. Some of the suggestions:

apt-get install ca-certificates
apt-get install ssl-cert

But did not help.

How to solve the issue and install Chrome safely without ignore the certificate as I want secure installation.
