Can not install <pga> package

[gezhe0821]

All other sub-Addons of FUTURES are successfully installed, only r.futures.pga fails to be installed, and the error messages show "[10060] A connection attempt failed because the connecting party did not properly reply after a period of time or the connected host became unresponsive."
By the way, My GRASS GIS version is 7.8.

A current statement is that a new Addon called r.futures.simulation replaces the .pga, so I have to update the sofeware version to 8.2 to install the r.futures.simulation and then, install pga pachage?

The error message sounds like some temporary problem with connection, have you tried to repeat it? r.futures.pga was renamed to r.futures.simulation, but both should work thanks to a wrapper script for backwards compatibility. When installing FUTURES, use g.extension r.futures to install all the components, not each one separately.
