I did no upgrade whatsoever. I saw mentions of Diablo and Chinook here and there but could not find any explanation what these codenames mean.

What is reported by About product screen is: OS2008, version 1.2007.42-19

Thanks!

Update:
So I tried to install the Chinook version of omweather from here: https://garage.maemo.org/frs/?group_...elease_id=1998

But I got the same error. I will try upgrading the OS2008 version to Diablo and try again.
