I’m trying to install webcam-gspca2 but I keep getting this error?? what should I do?

Have you updated your machine with the latest patches? Do that first and you may have to install the corresponding gspca2 package.
Check the kernel version first:

uname -r

the kernel version is
I use the Updater Applet for system updates and its updated for now. Plus all my repositories are enabled and on auto-refresh.

It looks like you are using an older version of openSUSE and trying to install latest gspca2 driver.

See if you can install (or upgrade to) openSUSE 11.2 and try.

works, thanks
