qtscript was updated to the latest version and still trying to track down the dependencies that want 5.15.10 instead of 5.15.11.

Comment 3 Carlos De Maine 2023-11-30 06:15:17 UTC

turned out to be some pins holding back qtscript* packages. should be able to upgrade now

I confirm. It's OK now. Thanks.
BTW, what are "pins" in this context?

Lines like

    Package: libqt5script5
    Pin: release o=jammy
    Pin: version 5.15.10*
    Pin-Priority: 1100

in apt preferences, specifically `/etc/apt/preferences.d/99-jammy-overrides` in this case.

Comment 6 Carlos De Maine 2023-12-08 03:52:52 UTC

correct.  useful when we make packaging mistakes etc.  the trick is keeping track of what is pinned and why :)
