Install of Ubuntu clears attributes on EFI System Partition

Bug #1768403 reported by David on 2018-05-02

parted (Ubuntu)

Bug Description


Installed Ubuntu 18.04 beside existing OS and utility installations, some of which require some of the attribute bits from 48-63 on the EFI System partition to function properly, unfortunately the Ubuntu install zeroed out those bits (in this case bit 55 was needed) when it shouldn't be touching them at all.

Please Fix to not modify the attributes of the EFI System partition. The UEFI Spec clearly states to preserve the bits.

It was 18.04 desktop. But it also affects things based on Ubuntu like Mint. So it's in your core installer somewhere (maybe grub2?), i can reinstall fedora and pclos to ensure they didn't turn off the bit, I don't recall them doing so.
