error when running apt-get update on ubuntu 14

  • 772

I am running ubuntu 14 on one of my servers.

When I run sudo apt-get update, I get the error below. 

W: GPG error: http://cran.rstudio.com trusty/ Release: The following signatures were invalid: KEYEXPIRED 1445181253 KEYEXPIRED 1445181253 KEYEXPIRED 1445181253

Should I modify my ppa repository list or take some other action to fix this issue.

Update: I tried removing R from the server using 

sudo apt-get --purge remove r-base
sudo apt-get --purge remove r-base-core
sudo apt-get --purge remove r-base-recommended

However, I am still seeing the same issue with apt-get update.

ubuntu-14.04

  1. Look at the "Secure APT" part of https://cran.r-project.org/bin/linux/ubuntu/README.html:

    Adding the key with key ID E084DAB9 fixed the problem for me.

    sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

  2. If you don't need R you can just remove the cran line from /etc/apt/sources.list and you should be good to go.

    sudo apt-key del 1445181253 will remove the offending key.

  3. Sorry for the abrupt questions but what has java to do with the 3rd party repository that you have set in your repository?

    Also I see you are capable to change your repository but not able to read the output of an error.

    You can add the missing key for the 3rd party repo:

  4. In case your firewall blocks port 11371, a more general solution is to force using port 80 when retrieving the new key:

    gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys E084DAB9
gpg -a --export E084DAB9 | sudo apt-key add -
