virtualbox kubuntu kpackage kit always uninstalls things to install new ones

Asked by nathaniel pissoff swanson

I have tried 10.10 and natty version of kubuntu. I have a 30 gig - dynamically allocated - virtual disk image (vdi file) harddrive partitioned by virtualbox software out of my physical hardrive. nearly every time i get something from kpackage kit, it insists that operations need to be performed, something i recently got is removed to install new items. why is this? it has happened 20 times

Its due to the way dependencies are handled and is normal.

For example, I might want to write some software which uses the "A" library version 1, which I call program "B 1.0". The A library releases a new version of their software, A version 2. As the developer, I decide that the A library version 1.0 is not as good as the 2.0 version, so I change my program to use A 2.0, and release the updated version of B, B 2.0.

Subsequently, you install B version 1.0, and A version 1. An update for your computer arrives for B 2.0, but the computer realises that B now uses A 2.0, and A 1.0 is thus no longer required.

There are many different scenarios for the above type of problem, including programs that cannot be installed side-by-side. Your computer is calculating the solution to these problems, and determining what software can be removed (as it is not used anymore) or otherwise needs updating too.

Can you help with this problem?
