Thank you for taking the time to report this bug and helping to make Ubuntu better.
Bug reporting is about finding & fixing problems thus preventing future users from hitting the same bug. You seem to need support more than have issues with a bug I believe a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu (this bug report can be converted to a question (which is aimed at support)). You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org, or for more support options please look at https://discourse.ubuntu.com/t/community-support/709 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to b43-fwcutter in Ubuntu. https://bugs.launchpad.net/bugs/1968414 Title: installing wifi adapter on macbook air 2015 model Status in b43-fwcutter package in Ubuntu: New Bug description: installing wifi adapter on macbook air 2015 edition ProblemType: Package DistroRelease: Ubuntu 20.04 Package: firmware-b43-installer 1:019-4 ProcVersionSignature: Ubuntu 5.13.0-39.44~20.04.1-generic 5.13.19 Uname: Linux 5.13.0-39-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.21 AptOrdering: b43-fwcutter:amd64: Install firmware-b43-installer:amd64: Install NULL: ConfigurePending Architecture: amd64 CasperMD5CheckResult: skip Date: Sat Apr 9 06:56:23 2022 ErrorMessage: installed firmware-b43-installer package post-installation script subprocess returned error exit status 1 InstallationDate: Installed on 2022-03-19 (21 days ago) InstallationMedia: Ubuntu 20.04.4 LTS "Focal Fossa" - Release amd64 (20220223) PackageArchitecture: all Python3Details: /usr/bin/python3.8, Python 3.8.10, python3-minimal, 3.8.2-0ubuntu2 PythonDetails: N/A RelatedPackageVersions: dpkg 1.19.7ubuntu3 apt 2.0.6 SourcePackage: b43-fwcutter Title: package firmware-b43-installer 1:019-4 failed to install/upgrade: installed firmware-b43-installer package post-installation script subprocess returned error exit status 1 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/b43-fwcutter/+bug/1968414/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
