업데이트: 문제는 커널 5.3.0-24에 있는 것 같습니다. 23으로 부팅하는 동안에는 정상적으로 작동합니다.
오늘부터 내 Kubuntu 19.10 시스템이 Wi-Fi에 연결하려고 하면 작동이 중단됩니다. 부팅 시 다음 오류가 표시됩니다.
iwlwifi 0000:03:00.0: Direct firmware load for iwl-dbg-cfg.ini failed with error -2
그리고는 말한다
loaded firmware version 29.62a39462.0 op_mode iwlmvm
Intel 드라이버는 이틀 전에 업데이트되었으며 이 오류가 발생한 후 드라이버 관리자를 열려고 했을 때 작동하지 않습니다. 그냥 앉아서 시스템에 대한 정보를 수집하는 중이었습니다.
모듈을 제거하고 다시 로드해 보았는데 작동하지 않습니다. 이것을 설치하거나 복구하는 방법을 알아보기 위해 웹에서 아무것도 찾을 수 없습니다.

같은 문제가 발생했습니다. 지금까지의 해결 방법은 커널 버전 5.3.0-23-generic으로 다시 전환하는 것입니다. 이제 예상대로 작동합니다.
