is there any chance the gnome-shell-extension-dash-to-panel package gets updated before the release of jammy? The current package 45-1 no longer works with gnome 42. There is a MR which enables 42 support and hopefully will be merged soon.
The MR does not work with gnome 42.beta (which is currently in jammy), since it already reflects some changes made in gnome 42.rc. But it does work with 42.rc and 42. So it could be updated once the final gnome-shell packages hit jammy.
