Public bug reported:
I follow Ubuntu Impish/development on my laptop (Lenovo ideapad
5-15IIL05/81YK00QYRA)
I have all recent Impish updates and kernel linux-image-generic
5.11.0.18.19+21.10.1 into which I rebooted on Jun 5th
Once I tried to plug into it an USB headset Jabra Evolve 20 MS and found that
it is visible by lsusb as device 0b0e:0300 but not in audio devices. In dmesg
-w, I see two lines
Lockdown: systemd-udevd: unsigned module loading is restricted; see man
kernel_lockdown.7
appearing immediately after plugging this device.
I compared this hardware support with Ubuntu Focal LTS on the nearby
Asus X302LA and found that its modules are loaded as expected, and it
becomes visible, usable and manageable to all audio utilities
(alsamixer, pavucontrol, firefox, vlc, whatever)
Can this please be checked with Impish and fixed in some way ?
I could not determine what module it deems unsigned.
Ready to collect and provide additional required information on your
request.
