https://bugs.kde.org/show_bug.cgi?id=466671 Alessandro Astone changed: What|Removed |Added Resolution|--- |UPSTREAM CC||ales.ast...@gmail.com Status|CONFIRMED |RESOLVED --- Comment #5 from Alessandro Astone --- `pkcon refresh` takes less than a second because it does nothing in Fedora. That is, unfortunately, intended. We have to use of `force` (or `--cache-age 1`) to actually download the new metadata: https://src.fedoraproject.org/rpms/plasma-discover/blob/rawhide/f/discover-5.21.4-pk_refresh_force.patch But improvements are coming: - https://github.com/rpm-software-management/libdnf/pull/1626 - https://github.com/PackageKit/PackageKit/pull/678 - https://invent.kde.org/plasma/discover/-/merge_requests/640 -- We need to use `--cache-age 1` instead of `force` to make use of the other upstream improvements With that it'll only be a bit slower than `dnf makecache` -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=466671 --- Comment #1 from Aleix Pol --- That's interesting. Would you be able to run "pkmon" in parallel to one of these tests? It would help us pinpoint which is the transaction that is taking londer. It should take something similar to what pkcon does (~8s). -- You are receiving this mail because: You are watching all bug changes.
