TLDR: - if you press the "Back" key after partitioning, Ubiquity fails to repartition (Ubuntu 18.04-beta2), possibly bricking your PC.
This is definitely a problem because it bricked my Surface Pro 2: - the error message only said there was an error, without any explanation; - same error even after changing the formatting options (encryption, etc); - after a reboot, Surface Pro 2 always shows its BIOS menu (which is limited to only two options: Secureboot and TPM) and won't boot Ubuntu USB installation anymore; - the LED near the microSD port of the Surface will blink the sequence "3 short, 3 short, 3 short, 4 short, 1 long", meaning Firmware Panic "Secure Boot Loader loop" - if you try to start the Ubuntu USB drive installation, it will blink "3 short, 4 short, 2 short, 1 short, 1 long" and won't boot anyway. Why it happened: - after starting installation and selecting Erase Disk + LVM encryption and clicking on Continue, I noticed I had Caps Lock still set; thus I clicked the "Go back" key when it became available again, wishing to restart the procedure using a password without all-caps; Ubiquity wouldn't be anymore able to go on. Suggestion: - repartitioning and formatting should only end when the partitions are in a clean state (for example including EFI files/structures required to boot). Workaround: reinstall Windows from its "Recovery" USB drive (this will wipe the internal SSD and set up a clean EFI thing), then reinstall Ubuntu again: - enable secure boot again from BIOS (power on while keeping VolumeDown pressed until the BIOS menu appears); - reinstall Windows 8.1 from Recovery Drive (I created it on day one and kept that 8Gb USB drive in a safe place, including credentials for my never used Microsoft Account and my alternate email to receive the safe code at install time; the limited BIOS of the Surface Pro 2 will boot a Recovery Drive only if secure boot is enabled); - boot Windows and go to PC Settings, select Alternate Boot menu (in the Update section of Settings) and choose USB drive boot; - it won't boot Ubuntu USB drive at first (because it requires secure boot disabled); power off, then, while keeping the VolumeDown pressed, power on again and disable secure boot; then power off, insert Ubuntu install in the USB drive, keep VolumeDown pressed while powering on - install Ubuntu as usual without going "Back" after partitioning. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761964 Title: Crash after formatting with LVM and encryption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1761964/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
