The bcmwl-kernel-source package should be updated to the version in focal-updates. 4) Actual result: apt considers the package from focal-updates a downgrade, leaving the system with broken WiFi after updating to the HWE kernel. $ apt-cache policy bcmwl-kernel-source bcmwl-kernel-source: Installed: 6.30.223.271+bdcom-0ubuntu7 Candidate: 6.30.223.271+bdcom-0ubuntu7 Version table: *** 6.30.223.271+bdcom-0ubuntu7 100 100 /var/lib/dpkg/status 6.30.223.271+bdcom-0ubuntu7~20.04.3 500 500 http://de.archive.ubuntu.com/ubuntu focal-updates/restricted amd64 Packages 500 http://security.ubuntu.com/ubuntu focal-security/restricted amd64 Packages 6.30.223.271+bdcom-0ubuntu5 500 500 http://de.archive.ubuntu.com/ubuntu focal/restricted amd64 Packages $ sudo apt install bcmwl-kernel-source=6.30.223.271+bdcom-0ubuntu7~20.04.3 Reading package lists...
