Public bug reported: It appears that mainline kernel builds (on kernel.ubuntu.com) have been failing for amd64 since v4.20.1. Interestingly enough v4.20 was able to build successfully.
Note: this also includes 5.0rc builds as well. You can see the build logs here: https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20.1/BUILD.LOG.amd64 https://kernel.ubuntu.com/~kernel-ppa/mainline/v4.20.2/BUILD.LOG.amd64 Looking at the build logs it appears that the kernel and all the in-tree modules build successfully, but the build fails when trying to build the proprietary nvidia kernel modules. With v4.20 building these modules does not appear in the log. Perhaps this build step was added more recently? Here are the relevant lines from the end of the build log for v4.20.2 (which I've also attached): ------------------------------------------------------------------------------------------------- 2019-01-10 03:38:12 (105 MB/s) - 'nvidia-kernel-source- 390_390.87-0ubuntu4_amd64.deb' saved [8433608/8433608] II: dkms-build downloading nvidia-390 (nvidia-dkms-390_390.87-0ubuntu4_amd64.deb) --2019-01-10 03:38:13-- http://us.archive.ubuntu.com/ubuntu/pool/restricted/n/nvidia-graphics-drivers-390/nvidia-dkms-390_390.87-0ubuntu4_amd64.deb Resolving us.archive.ubuntu.com (us.archive.ubuntu.com)... 91.189.91.26, 91.189.91.23, 2001:67c:1562::16, ...
