You're not doing anything wrong; it's just the way it is.<br>
<br>
The way yum works; both the downloaded .rpm files and the unpacked<br>
files have to exist at the same time briefly. yum calculates this<br>
and tells you it won't work.<br>
<br>
Removing the swap file will save you no more than 64MB, and will make<br>
the laptop slower afterwards.<br>
<br>
If you are insisting, for some reason, on ignoring my recommendations;<br>
let me give you one more to ignore; mount a USB drive over /var so<br>
that yum uses it for the downloaded .rpm files. That way, the<br>
downloads won't count against the root filesystem space.<br>
