How could I install it ?

You must first convert the cer file into a crt file.
openssl x509 -inform DER -in <fullfilepath>/certificate.cer -out certificate.crt
Then to install do the following:
sudo mkdir /usr/local/share/ca-certificates/my-custom-ca
sudo cp certificate.crt /usr/local/share/ca-certificates/my-custom-ca
sudo update-ca-certificates
You can find the full installation procedure here.
