in the past, I installed Qubes OS R4.0.X (for some X I cannot remember) for fun and everything I tried out worked fine (including Internet connection).
Today, I decided to install R4.1.2 with defaults on the same machine. The installation and configuration process went fine but one of the last steps: Setting up network didn’t seem to work. I got an error message I cannot remember exactly but I’m quite sure it’s the one I reproduce below in this post.
After clicking the message away, Qubes OS started and I logged in. But starting the sys-net VM failed – again with the same error message.
So, I decided to install R4.2.0-rc5 but I got a similar error message again. After logging in immediately after installation, I got the same error message again when starting the sys-net VM. This time, I copied the error message, reproduced here:
qrexec-daemon startup failed: 2023-12-01 13:12:30.644 qrexec-daemon : qrexec-daemon.c:144:sigchld_parent_handler: Connection to the VM failed
In addition to that error: I rebooted Qubes OS and then I
could not start the Q-menu,
missed some tray icons,
could not start any qube,
could not shut down Qubes OS cleanly.
However, I can open a dom0-terminal.
So, what can I do in order to make everything work?
Your system seems to be pretty broken. How did you flash the Qubes ISO (software and options)?
In sys-net settings, do you have any PCI devices selected in the Devices tab? Can you start the qube if you remove that device from there?
thank you for your quick reply. I started Qubes OS again and was suprised that the Q-menu could now be opened and the tray icons re-appeared. So, I removed the Wireless Network Adapter from the device list of sys-net and it worked! (I now remember that Wireless Networking didn’t work at all in R4.0.X, probably the adapter was not detected.)
To the Qubes OS developers: I propose to remove failing network devices from the device list when setting up network configuration / sys-net during installation.
Oh, and I used ddpolymerase, my own tool for copying, repairing and verifying files (like ISO images). After your reply, I successfully re-verified the installation medium with it. Also, the self-test of the Qubes OS installation medium said that everything is fine. So, I consider three reasons for the weird behavior (like the non-openable Q-menu):
the issue with the Wireless Network Adapter during the installation process (configuration stage),
If this is related to the network card, add it back to the selection and enable “strict reset” for it (it’s a button at the bottom of the same tab). Restart sys-net and see if it runs without crashing.
You can also copy to the clipboard using Qubes Manager. Right click on sys-net, choose “logs” and copy/paste (ctrl + shift + v) here with the “Copy to global clipboard” button.
Don’t forget to put them in a formatted text block.
Thank you, DVM, for your support! I re-installed Qubes R4.2.0-rc5 with “kernel-latest” option but the error remains. Compiling and installing a driver manually seems too sophisticated to me for now (even though I’m a developer). And since my wired ethernet works … I don’t need WiFi for now. It’s not urgent. Maybe, I’ll think about it later.
