Bug 504685

SUMMARY
KDE Linux installer won't run through icon or welcome center.
Calamares starts through CLI (sudo calamares), but fails to install.
CLI hangs on, "chcon: failed to get security context of '/efi': Operation not supported."

STEPS TO REPRODUCE
1. Double click on "Install System" icon on desktop, and/or click on Welcome Center's option to install.
2. Wait. Calamares icon shows, and then disappears, never actually running.
3. Through CLI, Calamares runs under sudo, but fails to install.

OBSERVED RESULT
Calamares never starts.
Under CLI, with sudo, Calamares starts, but progress freezes during installation.
From CLI: "chcon: failed to get security context of '/efi': Operation not supported"

EXPECTED RESULT
Installation of KDE Linux
