Most of the photo imaging software for Ubuntu are front ends for
gPhoto2, and its not listed as a compatible camera on that program's
website at:

and on it says the

"For the protocol, there are 2 USB standardized protocols that digital
camera uses: USB Mass Storage and PTP (aka Still Image Device). If a
camera doesn't use one of these two protocols, it surely uses a
proprietary protocol, and this is were things get uneasy: most
manufacturers don't disclose these protocols for various reasons."

I would guess that its not on the list (while other Pentax Optio
cameras are) because its not a Mass Storage Device, by which I mean it
doesn't meet with the protocol for Mass Storage Devices, and the driver
hasn't been back engineered as yet.

The camera does have a removable memory card and I suggest you get
yourself a card reader to plug into your usb port or hub which can read
your card, as others have suggested.
