failed to map sideband memory: Operation not permitted

[GerardoGR]

When running the firmware-manager from the command line. I always see the following error:

$ sudo firmware-manager 
[INFO ] firmware_manager src/system76.rs:11: scanning for system76 devices
[ERROR] firmware_manager src/system76.rs:24: failed to download system76 changelog: calling Download method failed: "failed to map sideband memory: Operation not permitted (os error 1)"

@ahoneybun (of system76's support team) and I were not able to find out the root cause for this. I wonder if this prevents me from getting the latest firmware versions.

Also to note: I've installed firmware-manager via paru -S firmware-manager which in my machine uses rust=1.60.0-1

@GerardoGR can you list your partition layout as well as the version of the firmware-manager.

I think a better place for this issue is at https://github.com/pop-os/system76-firmware because the error is actually coming from the system76-firmware-daemon. I'll close this issue in favor of a similar issue there: pop-os/system76-firmware#82. But for me this is still a current issue.
