BTW, I just discovered that aptitude has recently learned a nifty new trick, the "why/why-not" command: $ aptitude why-not digikamimageplugins i kde-extras Recommends digikam p digikam Conflicts digikamimageplugins This is really useful to figure out what is going on with complicated dependency issues. It is currently only available to Sid users, though (aptitude version 0.4.5.3 or higher).
Wonderful new features! I just noticed that 0.4.5.4-1 is now available in Testing. Going to upgrade right away.
Now, how do I know why these removals are necessary? And how do I find out if I should go ahead with the upgrade since, maybe the new package has the two packages built-in now?This information is often included in the package description. For digikam you can find this: "All plugins previously provided by the digikamimageplugins package are now included in this package."
Ah, that clears up that bit. Thanks, ->HS
Failing that, you can download and read the changelog of the package before installing or upgrading.
