I am trying to install the driver for my Epson WP-4530 printer. I have just installed Ubuntu 12.04 LTS. My printer is connected to my home network router. The Printer install utility is able to detect the printer and find the driver for it. It recommends to instal the Epson Inkjet printer driver for Linux (Version 1.0.2). However, when I select the driver and click the activate button I receive the following error
SystemError: failed to call gpg: [Errno 2] No such file or directory
There is no help. I don't know what this error means and I haven't found any useful help using google searches.
