Hi All,
I am plain curious what goes on under the hood in HAM (Hildon App Manager) when we click an install link from the web/or install file from file manager.
From what is visible, HAM stays put with a scroll bar and message preparing for installation. In case of Ovi Store apps, it stays like that for almost eternity.
What is actually being done behind the garb of "Preparing for installation" ? Is it updating the catalogs again? If yes, then why when the catalogs are freshly updated. Why must it do this for every app that we try to install?

First it will add the appropriate application repository if you don't already have it, it'll then clear your apt-get cache and update all repos.

Then it downloads and installs your chosen application.

I think the default behavior when browsing or installing apps in HAM is to purge your apt cache and reload. It takes forever and maxes our your CPU, but that's what it is.

Since three's no GUI option in HAM to purge/rebuild your apt cache, it would be folly to try and change this default behavior deeper in the application configuration (if that's even possible), since your app manager would quickly become out of sync with whats on the repository servers (unless you make a habit of rebuilding your apt cache from the x-terminal)
