The dnfdragora-updater notification icon shows up in the systemtray typically just once per boot. Once it is closed it does not show up again.
It is possible that a transient popup notification shows up, but I’m not always there to observe it.
dnfdragora-updateris set to autostart
ps aux | grep dnfconfirms
dnfdragora-updaterprocess is running
dnf-makecache.serviceruns successfully every hour. Metadata cache is refreshed every 180 minutes.
I’m on Fedora 30 MATE now but this has been the case with Fedora 28 and 29 too.
Also, updating with
sudo dnf update does not make the dnfdragora-updater icon disappear once there are no more updates to install.
