Rock64 Xenial Mate Community Build Image [microSD to eMMC] [0.5.15-136]

[t4_4t]

"Failed to execute program org.freedesktop.systemtoolsbackends permission denied."
I confirmed about.

The environment is the state where all "UpDate" as of today are applied to the following images.

xenial-mate-rock64-0.5.15-136-arm64.img.xz

I did not want to destroy the environment of eMMC, so confirmed with microSD
Although slightly different from the main theme [microSD to eMMC]
Since the same error came out, I think that the essential problem has not changed.
"System -> Administration -> users - admin",
"System -> Administration -> Network",
"System -> Administration -> Time and Date"
These errors have disappeared

However, "Stikky-Bit" will come off when you do this street operation.
I think that the reverse order is better
