I don’t think you need update the keys, how are you trying to install the chrome in the template? Try like this in fedora-40-xfce: Edit /etc/yum.repos.d/google-chrome.repo file and change enabled=0 to enabled=1. Install chrome:
/etc/yum.repos.d/google-chrome.repo
enabled=0
enabled=1
sudo dnf install google-chrome-stable
Maybe you want to install wget and not wvget?
wget
wvget
