          It happens in 1371/8512 years, which is about 16.1%.

            Could you add something about how you arrived at (or sourced) that number?

          • Where do you get 1371/8512 from? My reading of the Tur’s chart gives 40/247, which is slightly off but still rounds to 16.1%. Where does the difference come from? (And what does 8512 represent? I know of 19 year cycles, 247 year cycles, and over 600K year cycles, but 8512 is new to me.)

          • Ah, makes sense now. So 8512 doesn’t mean anything in particular, that’s just the most reduced fraction?

          Boot-repair Failure: Unable to locate package grub-common:i386

          0 I am on a system dual-booting Windows and Debian (usually using the latter), and a recent Windows update appears to have wreaked havoc on the Debian boot system. I managed to boot Windows again, but not Linux. Following online suggestions, I created a Live USB of Ubuntu, and booted from that. Then I have installed and run the boot-repair utility. The utility instructs me to type several lines including sudo chroot "/mnt/boot-sav/sda6" apt-get purge -y grub*-common grub-common:i386 To which I receive the error E: Unable to locate package grub-common:i386 I am given to understand the issue may have to do with having UEFI vs BIOS (I believe I have UEFI), but do not understand this well. In any case I have subsequently run the boot-repair BootInfo Summary utility which created the following file h
