R SIG Debian - Aug 2015 - Server certificate verification failed

Hi all, I have the following in my apt sources.list file: deb https://
/bin/linux/ubuntu trusty/

I issued the following command to obtain the public key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9


I am receiving the following error message though after updating the
Synaptic package manager:
Failed to fetch
https://cran.revolutionanalytics.com/bin/linux/ubuntu/trusty/Packages
server certificate verification failed. CAfile:
/etc/ssl/certs/ca-certificates.crt CRLfile: none


Any assistance that you can provide will be helpful.

Thank you.

Irucka Embry

Irucka,

I just ran the "apt-key" command provided and it worked just fine.  I
am
able to find the key on keyserver.ubuntu.com by searching for "Michael 
Rutter".  You can download the key and add it with "sudo apt-key add 
key.txt".  There are alternate directions at 
https://cran.r-project.org/bin/linux/ubuntu/ as well.

Hope this helps,
Michael

is there any reason you want to use https rather than http?

this should go away if you use unencrypted http.

Kind regards,
