A short note on fixing an unresponsive GNOME Softwate application.
If you found yourself in a situation when the Software application ends up in endless loading state, the following might fix it for you:
$ sudo killall gnome-software $ sudo systemctl stop packagekit.service $ sudo systemctl stop packagekit-offline-update.service $ sudo rm -rf /var/cache/PackageKit/* $ sudo systemctl start packagekit.service $ sudo systemctl start packagekit-offline-update.service $ pkcon -v update
The above helped me to recovered from a bad Fedora 35 to 37 upgrade.

I wrote a complete guide on web application deployment. Ruby with Puma, Python with Gunicorn, NGINX, PostgreSQL, Redis, networking, processes, systemd, backups, and all your usual suspects.
