Thanks for this! I was using the launchpad ppa with 10.04, but now I am on Linux Mint 13 I need to update.
The first line seemd to go through fine, but the second one returns:
gpg –export –armor 1F9ADD375CA44993 | sudo apt-key add -
usage: gpg [options] [filename]
gpg: no valid OpenPGP data found.
Do you have any suggestions?
Thanks!
