Hello satmandu, or anyone else affected, Accepted backport-iwlwifi-dkms into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source /backport-iwlwifi-dkms/7906-0ubuntu2~19.10.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: backport-iwlwifi-dkms (Ubuntu Eoan) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-eoan -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers-430 in Ubuntu. https://bugs.launchpad.net/bugs/1830961 Title: Kernels & kernel drivers fail to build with gcc-9 [error: ‘-mindirect- branch’ and ‘-fcf-protection’ are not compatible] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/backport-iwlwifi-dkms/+bug/1830961/+subscriptions ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

Redditer trying an upgrade from disco -> eoan reported broken upgrade due to this, and like in comment #34 I can reproduce this still.
