Removing PPA causing GPG error

  • 772

When I run 

sudo apt-get update

I get the following error:

W: GPG error: http://download.opensuse.org ./ Release: The following signatures were invalid: KEYEXPIRED 1436387333

How can I locate and remove the PPA which is causing this error?

    The command

    grep -r 'download.opensuse.org' /etc/apt

    shows where the repository is configured, e.g.:

    /etc/apt/sources.list.save:deb http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list.save:# deb-src http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list:deb http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./ 
/etc/apt/sources.list:# deb-src http://download.opensuse.org/repositories/home:/sarimkhan/xUbuntu_14.04/ ./

    In your case it is in

    /etc/apt/sources.list

    With this knowledge you can remove the entry with the help of sed

    sudo sed -i '/download.opensuse.org/d' /etc/apt/sources.list

    and to avoid confusion in the future you also should remove the entry in your backup file

    sudo sed -i '/download.opensuse.org/d' /etc/apt/sources.list.save

    Now update the package information

    sudo apt-get update

    and the problem is gone.
