We have an open ticket about that[*]; basically, the official NUT documentation needs to be a bit more explicit that the paths are what you would get with a vanilla source install, and that distributions will most likely be different.

If it's the same "coyote" machine from 2010, the archives indicate that you installed from source at one point. The Ubuntu packages shouldn't have written to /usr/local.

Yes, but the paths in those files are from the source install. I forget what Ubuntu did with the 10.04 packages, but it probably shipped *.sample files in either /etc/nut or /usr/share/doc/nut/examples.

Good question, but it's going to be hard to tease apart the Ubuntu .deb install and the source install.

Note that some versions of /etc/init.d/nut (provided by Ubuntu) will start the driver as well as upsd and upsmon, so the separate "upsdrvctl start" is not necessary.

Do you have anything else installed to /usr/local? If not, it might be easier to move that directory aside. Then again, if you installed from source, it was probably due to something not being in the Ubuntu packages.

With usbhid-ups, this tends to only happen when multiple drivers are running.
