SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download two short videos (registration required) highlighting:

Ubuntu gksudo deprecated - graphical install does not work

I found a solution however.
If no gksudo, it ought to be created gksudo.
It ought to be created gksudo, with alias in shell, instead of shell alias.
I created executable gksudo in /usr/bin with following context:
pkexec env DISPLAY=:0 XAUTHORITY=/run/user/1000/gdm/Xauthority DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus $1 $2 $3 $4 $5 $6 $7 $8 $9 $10
After I simply ran installer as it actually is gksudo.
However it later came troubles with compliance that replacement does not understand option -D, the same, I afraid, would be with offered shell alias.
