Comment (by veroandreo):

 I confirm that the commit fixed the problem in relbranch.

 >So far, it is not designed to work in Python 3. I have not yet upgraded
 my computers so I can't yet test. A coming step will be to develop a new
 workflow to compile GRASS in Python 3.

 Will this help: https://trac.osgeo.org/grass/wiki/Python3Support#Howtotest
 ?

   So far, it is not designed to work in Python 3. I have not yet upgraded
 my computers so I can't yet test. A coming step will be to develop a new
 workflow to compile GRASS in Python 3.

 It does work in trunk with no reported errors. However, if I run it in
 trunk compiled with python 3 in a virtualenv, I get:

 When compiling grass76_relbranch I got an indentation error in
 i.pansharpen at line 257
 
(https://trac.osgeo.org/grass/browser/grass/branches/releasebranch_7_6/scripts/i.pansharpen/i.pansharpen.py#L257)

 {{{
 File "/home/veroandreo/software/grass76_release/dist.x86_64-pc-linux-
 gnu/scripts/i.pansharpen", line 256
 pr.wait()
 ^
 IndentationError: unexpected indent
 }}}

 I entered the directory of i.pansharpen, run make, still the same error.
 So I open the code and locally moved lines 257-263 to the left.
 Compilation of i.pansharpen went fine, no errors. But when I try to run
 the examples in the manual page for Landsat 7 in NC Location, I get:

 {{{

 Is this related to the backport in r74385?
