[Bug 1951580] Re: backport-iwlwifi-dkms fails to build with kernel 5.15 jammy
Actually... is this dkms really needed in jammy? Now that the build is fixed I just noticed that I get this error if I try to install it on a 5.15 kernel: iwlwifi.ko: Running module version sanity check. Module has been obsoleted due to being included in kernel 5.14.0. We will avoid installing for future kernels above 5.14.0. You may override by specifying --force. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951580 Title: backport-iwlwifi-dkms fails to build with kernel 5.15 jammy To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1951580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
