I am new to QubesOS and currently looking for a way to update the firmware of my Notebook.
I had a Linux distro before which had the option of doing the firmware updates via a GUI.
I searched online for a way and found that since the Qubes 4.2 version that the fwupd is included.
I searched on their github and tried the following command: fwupdmgr refresh
I got this response:
failed to download file: Could not resolve host: cdn.fwupd.org.
It seems that dom0 does not have access to get the updates.
Then I was looking in the forum and people were recommending this approach:
I thought this “workaround” is not necessary anymore since the 4.2 version. Or is this the normal way to use commands in dom0?
Theres documentation for this feature currently missing:
The command you’re looking for is sudo qubes-fwupdmgr --help
Unfortunately it didn’t work for me. Command always froze and never finished even after multiple minutes, tried sys-firewall and sys-whonix.
This is by design. dom0 is isolated for security reasons.
Since you’re new you might want to do a bit of reading the documentation:
I was curious about this so I just tried it out. The packages were not installed for me in dom0. I had to install fwupd-qubes-dom0 (version: 1.8.14-5.fc37).
Running sudo qubes-fwupdmgr get-devices listed out several devices on my system.
I then found that I needed to run refresh before get-updates.
Running sudo qubes-fwupdmgr get-updates just hangs, as I believe previously mentioned. I suspect that the tool and command get-updates is attempting to read some data from a file that is empty or does not exist (until after running refresh). The traceback shows execution at a line intended to read data. Instead of generating an error, it just hangs.
Traceback after interrupting get-updates:
Traceback (most recent call last):
File "/usr/sbin/qubes-fwupdmgr", line 731, in <module>
File "/usr/sbin/qubes-fwupdmgr", line 709, in main
File "/usr/sbin/qubes-fwupdmgr", line 586, in get_updates_qubes
File "/usr/sbin/qubes-fwupdmgr", line 196, in _get_dom0_updates
new_data = os.read(mstdout, 4096)
Running commands in this order seems to work:
sudo qubes-fwupdmgr refresh
sudo qubes-fwupdmgr get-updates
No updates available.
