This is really a nasty one. I installed a brand new machine, did not have any problems. Then upgraded the graphics to nvidia 1070, and started having this same issue. Disabled the secure boot, problem went away, however, fstab mounted my second drive as home, as I had it before, now problem came back and I have no idea what to do.
Is it possible to get some workaround to disable this security entirely? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1743908 Title: MODSIGN: Couldn't get UEFI db list Status in linux package in Ubuntu: Fix Released Bug description: Kernel is having problem loading or validating certificates.
