Alberto is rolling this back into older releases over time. To be fair it is an annoying issue but not one that is so fatal one would not be able to recover a system. In the majority of cases this ends up being just a false system issue notification. Because on kernel update the parallel builds are actually started 3 times. By now I just made it a habit of doing the following whenever kernel updates come in:
- run "dkms status" to see whether both nvidia modules appear for the latest kernel (bbswitch is always there) - if one(or both) is missing, do "sudo dkms install -m <module> -v <module version> -k <kernel version> (the name and versions taken from the dkms status report) - "sudo rm /var/crash/*nvidia*" to ignore the build failures before When the fixed version of the driver hits this can be noticed by having only one module reported by dkms for nvidia. The *-uvm one will be gone and the module it produced will be part of the remaining dkms module which then produces two kernel modules. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331-updates in Ubuntu. https://bugs.launchpad.net/bugs/1431753 Title: Nvidia binary driver FTBS due to DKMS layer violation Status in nvidia-graphics-drivers-331 package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-331-updates package in Ubuntu: Confirmed Status in nvidia-graphics-drivers-340 package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-340-updates package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-346 package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-346-updates package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-331 source package in Trusty: Triaged Status in nvidia-graphics-drivers-331-updates source package in Trusty: Triaged Status in nvidia-graphics-drivers-340 source package in Trusty: Confirmed Status in nvidia-graphics-drivers-340-updates source package in Trusty: Confirmed Status in nvidia-graphics-drivers-346 source package in Trusty: Confirmed Status in nvidia-graphics-drivers-346-updates source package in Trusty: Confirmed Bug description: Filing this against the 340-updates version but possibly the same applies to older versions, too. The nvidia source package produces two individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm. The problem is that the DKMS build of the nvidia-uvm module runs compile steps inside the nvidia modules build directory. This is violating the DKMS assumption that each module can be build independently (there is no way of describing cross-modules dependencies and even more important, the autoinstall step after a new kernel is installed will run the modules build in parallel). Since nvidia and nvidia-uvm are very dependent on each other the right course of action seems to be to combine both sources in one DKMS module that produces two kernel modules (this is supported by DKMS). For the transition this resulting dkms package needs to have a breaks/replaces for the nvidia-uvm package.
