This bug is marked as "Fix Released" but after years of running Manjaro I decided to give Ubuntu a try again with Disco Dingo 19.04 and it was simply impossible because it still exists. I could get past the initial error, and Ubuntu thought it was installed, but trying to boot just output the error message on an otherwise black screen.
The message is the same as everyone else is getting: Couldn't get size: 0x800000000000000e MODSIGN: Couldn't get UEFI db list Couldn't get size: 0x800000000000000e So unfortunately I just had to reinstall Manjaro so I could get back to work. By the way this is the reason I left Ubuntu in the first place. If you want to run a years old OS with years old software you can use an LTS release that's fairly stable. But if you want a current OS and current software interim Ubuntu releases are most often disasters, right up until it's life cycle is over. And then the nightmare begins all over again. But if Ubuntu is ever able to maintain a distribution that's three months or less behind mainline I'll give it a try again. It would be nice to use .deb packages without translation. It's a shame, and I really don't understand. Manjaro and other rolling releases have nowhere near the problems Ubuntu has keeping up to date. Their only downside is that for the most part no one supports them, so you have to do a lot of customization and compiling of third party software. Anyway, good luck guys and gals. Despite my complaining I wish the best for Ubuntu. -- 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.
