I'm setting this bug as a duplicate of the kernel bug as u-u can't ensure upgrading kernel and modules in lockstep unless strict dependencies are set between the packages. ** This bug has been marked a duplicate of bug 1253155 Failure to validate module signature at boot time -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1431214 Title: Unattended-upgrades triggers kernel taint when rebuilding initrd Status in unattended-upgrades package in Ubuntu: Confirmed Bug description: Kernel logs from unattended-upgrades doing mkinitrd resemble Bug #1253155 symptoms.
