Hi David,

Can you add the following to your /etc/apt/sources.list and try the ones in my PPA.

The first snippet shows that the driver couldn't get the ratings from
the UPS, and without those values there's no way to calculate the
charge percentage. There have been some improvements in reliability
while talking to the UPS, so maybe that's why the newer version works.

You can always use the battvolts option though, like Arnaud said. And
it looks like you need to use it because the calculated percentage
doesn't look correct (assuming the UPS is fully charged). The thing
is, for a given nominal battery voltage, different models from
different vendors behave differently, and there is no way to tell them
apart to ajust the calculation.

@Chuck: I'll try them on monday since I am not at home for the weekend.
@Arnaud: It wasn't, I was suffering the bug 209001 issue. Hardy version was not working until nut_2.2.1-2.1ubuntu6, so I was using Gutsy version.
@Carlos: I'll check the "battvolts" option with the SVN version. Thanks.

Chuck, I tried your repo and installed nut version 2.2.1-2.1ubuntu7~ppa3 and everything seems to be working right:

As for the battvolts option, I don't really know the right values for "The battery voltage interval". I think I can live with that 97.5% :)

Thanks,

The update for nut should be uploaded to the archive soon. Thanks again for testing.
