Yes, uupd.timer is the unified update timer for Bluefin 43, responsible for managing both system and Flatpak updates. To change its schedule to run only on Wednesdays at 2 AM, create a systemd timer override as follows:
- Create the override directory and file:
sudo mkdir -p /etc/systemd/system/uupd.timer.d sudo nano /etc/systemd/system/uupd.timer.d/override.conf - Add the following content to
override.conf:[Timer] OnCalendar=Wed *-*-* 02:00 - Reload systemd and restart the timer:
sudo systemctl daemon-reload sudo systemctl restart uupd.timer - Verify the new schedule:
systemctl list-timers | grep uupd
If you have other update timers enabled (such as rpm-ostreed-automatic.timer or bootc-fetch-apply-updates.timer), consider disabling them to avoid conflicts, since uupd.timer is intended to be the main update mechanism. For more details, see the Bluefin GitHub issue #3245.
