Workaround to fix Gnome Shell Search Provider-integration
Not sharing a problem but a finding which might be useful for those whose Gnome Shell Search Provider-integration broke during one of the recent Ubuntu upgrades and in their search for a solution might also skim this list of issues.
gssp-recoll-1.1.1.tar.gz, the file referred on Recoll's Documentation, didn't fix it. However, what worked for me was to manually download gssp-recoll_1.1.1-1ppa2kinetic1_all.deb from Recoll's Launchpad.
Noteworthy, the provided gssp-recoll version (22.10 - kinetic) works well, despite running on the latest Ubuntu (23.10 - mantic).
