I want to create a USB gadget with a raspberry pi zero 2W. I'm starting with imitating a webcam I already have to see how much of this I can figure out. I've used the online documentation and a couple AI bots to get this far quickly, but I'm hung up on a ln command. It's telling me "ln: failed to create symbolic link 'configs/c.1/uvc.usb0': No such file or directory" when trying to create the link. This makes no sense to me though. I'm trying to create the link, of course it doesn't exist yet. That's what that command is supposed to do.

I've confirmed this problem in alpine linux and raspbian lite.

Below is the little script I have so far just to create the device:

\#!/bin/bash
modprobe libcomposite
cd /sys/kernel/config/usb_gadget/
mkdir -p fauxcam
cd fauxcam
echo 0x046d > idVendor  # Logitech Vendor ID
echo 0x094b > idProduct # Brio 105 Product ID
echo 0x0200 > bcdUSB
echo 0x9914 > bcdDevice
mkdir -p strings/0x409
echo "111111111111" > strings/0x409/serialnumber
echo "Brio 105" > strings/0x409/product
mkdir -p configs/c.1/strings/0x409
echo "UVC Configuration" > configs/c.1/strings/0x409/configuration
echo 250 > configs/c.1/MaxPower
mkdir -p functions/uvc.usb0
ln -s functions/uvc.usb0 configs/c.1/
echo "usb0" > UDC

I am trying to update from Silverblue 41 to 42 (fully updated) but run into issues when attempting to update from both the software app and from CLI.

The problem using the software app is the same as what is described by this other user, who is using Fedora Workstation not Silverblue like I am:

discussion.fedoraproject.org/t…

When I click the download button, it looks like it's downloading multiple files since the progress bar goes from 0 to 100 several times, and then it gets up to 95% then suddenly returns to the download button. This happens in about 30 seconds.

Using the CLI method, I run the following command:

rpm-ostree rebase fedora:fedora/42/x86_64/silverblue

and get the following errors:

```error: Could not depsolve transaction; 1 problem detected:

Update to Fedora 42 fails in gnome-software

Most of my machines seem to be working fine, but I have one critical one where I have the notification for Fedora 42 in the gnome-software updates window, but when I click the Download button, the progress bar shows up to about 4% and then quits with…
