I've been daily driving Kubuntu for ages now (currently on 24.10), and I've noticed that updates take a while for seemingly no reason.
The downloads are slower than my internet is capable of, but they happen fast enough. It's just that some packages take longer than I would expect on the "unpacking" step.
For example, anytime there's a new kernel release or new headers, apt downloads the packages fast enough, but the unpacking takes time with seemingly no resource usage. No increased CPU load (for possible inflating of a compressed archive), no IOWAIT warnings, my NVMe disk shows very little throughput (and can handle much faster disk operations, like downloading games via Steam), stuff like that. The system seems to be at idle, and yet the unpacking of some packages just... takes a while.
It's not like it's a huge issue. It's only maybe an extra 30+ seconds, but it's got me wondering if there's anything I could do to improve it.
sudo apt clean
hasn't had any effect, and my Google searches are of people complaining of either slow download speeds or 30+ minute delays that end up being failing drives.
Anyone have ideas?
