Comment 8 for bug 1189916

StSav012: Unfortunately, it's not that simple. The package manager runs the install/upgrade as root, so I can't run the script there (which I found out the hard way -- that's why the .28 upgrade was failing for some users).

Anyway, the latest unstable build will now automatically detect the old settings format and update it to the new one.

You can get it from the PPA here: https://launchpad.net/~weather-indicator-team/+archive/unstable
