Unable to upgrade dom0 packages using qubes-dom0-update

Using the microcode_ctl package as an example (although this is the case for other packages as well).

This confirms that there is a new version available:

# dnf list installed microcode_ctl

microcode_ctl.x86_64      3:2.1.20260210-58.qubes1.fc37       qubes-dom0-current
There are dom0 updates available

But trying to install it gives the following output:

# sudo qubes-dom0-update microcode_ctl

So in the end, dnf list installed microcode_ctl still shows the old version.

Nevermind. From "qubes-gui-daemon-4.1.15 is already installed" when attempting to update to qubes-gui-daemon-4.1.18 · Issue #6979 · QubesOS/qubes-issues · GitHub

when you want to update specific package (you give package name on the command line), you need to add also --action=update , as the default action if package name is given is to install (some version) of that package only.
