* Build grub2-unsigned packages with xz compression for compatibility
with xenial dpkg
- update debian/rules
[ Steve Langasek ]
* Bump versioned dependency on grub2-common to 2.02~beta2-36ubuntu3.32 for
necessary arm relocation support. LP: #1926748.
* debian/postinst.in: Unconditionally call grub-install with
--force-extra-removable on xenial and bionic, so that the \EFI\BOOT
