Comment 24 for bug 1859308

This looks very similar to bug #1878553.

ubuntu-drivers-common reports that iwlwifi is "manually installed" because "modinfo iwlwifi" returns !0. This causes software-properties-gtk to display this confusing, mostly greyed out piece of UI.

The iwlwifi module is part of the kernel (/lib/modules/5.4.0-31-generic/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko is installed by linux-modules-extra-5.4.0-31-generic), which explains why the adapter card works out of the box. Therefore the DKMS module really shouldn't be needed in most cases (although I'm not sure how often the module is updated as part of kernel updates VS backport-iwlwifi-dkms updates).

ubuntu-drivers-common probably needs to be made aware of such modules shipped by the kernel, to avoid incorrectly labelling them as "manually installed".
