Cannot build LVM2: Permission denied

Hello,

I am trying to create zuluCrypt Flatpak package.

It need dev-mapper as dependency.
dev-mapper is from LVM2.

Here is the Flatpak manifest.

runtime: org.freedesktop.Platform
sdk: org.freedesktop.Sdk
runtime-version: ‘20.08’
command: zulucrypt
finish-args:

But I cannot build LVM2.
