GPG Error solution.
The distribution that I'm using here is pc-os-open64wstation and this is based on Xubuntu 9.04 jaunty jackalope. For other distributions the commands given for the solution might need to be modified – but I'm not sure (it might work as is).
Initially after establishing an ethernet broadband connection you would launch the Synaptic Package Manager and reload the list of packages. Until you do so the system may not become aware of hardware drivers such as the NVIDIA graphic driver:
PC/OS > System > Synaptic Package Manager
Enter the password.
Click the Reload button.
Mostly it works but in the open64 distro you get this:
An error occurred:
W: GPG error:
http://packages.medibuntu.org.jaunty Release: The
following signatures couldn't be verified because the public key is not
available: NO_PUBKEY 2EBC26B60C5A2783
Click the Close button here.
You would tend to continue at this point by clicking the 'Mark all upgrades' button and download all these (366MB or so). Then close Synaptic Package Manager.
Open a terminal and enter the following commands (easier said than done – not the terminal again):
PC/OS > Accessories > ROXTerm
wget -q
http://packages.medibuntu.org/medibuntu-key.gpg -O- | sudo apt-key add - && sudo apt-get update
* The above is one line and for best effect copy and paste it into the terminal (easier said than done). Although copying it should be easy enough, to paste it you need to select Edit > Paste at the top of the ROXTerm window.
It will then ask for your password, so give it.
It then does lots of stuff and says done.
Close the ROXTerm window.
If you now check on Software Sources:
PC/OS > System > Software Sources, Third-Party Software tab.
You should now see (ticked) Medibuntu – Ubuntu 9.04 “jaunty jackalope” free non-free, is present. Hopefully if your distribution is different the line will reflect the different distribution. It will also be listed in the Authentication tab.
