Hi Casey,

Looks like recent ubuntu does not include the `at` command by default. You can install it using: 

`sudo apt-get install at`

Alternatively you can use the 'background' execution mode, which should work on most systems (it's the default). Not sure how panda has set up it's configuration, but in psom it looks something like:

`opt.mode = 'background';`

You may want to get in touch with the PANDA developers on their dedicated forum:

Best,

Pierre
