I am attempting to do my own build of Android for the DragonBoard 410c using the materials from Qualcomm under Ubuntu 20. I have downloaded from the Qualcomm developer portal the file, linux_android_board_support_package_vla.br_.1.2.7-01010-8x16.0-4.zip, containing the materials which I have unzipped into a folder ~/Documents/linux_android_board_support_package_vla.br.1.2.7-01010-8x16.0-4 making the materials available include the shell script DB410c_build.sh.
The unpacking and setup is done by DB410c_build.sh which performs the various actions such as generating the .repo directory tree with the python files that are used by the shell script and downloading the source.
I have run into a number of syntax errors from the various python scripts, it appears this was written for python 2, that I have been able to address thus far. By the way, python --version reports python 2.7.18 yet I still see errors indicating python 3 is being used.
The latest error comes from the python script, .repo/repo/subcmds/smartsync.py and when it executes, I get the following error that I have been unable to figure out or find a solution through searches.

Most of the previous errors have been due to incorrect syntax with except and raise as well as print along with a couple of import errors that were easy to find solutions for (Thank you StackOverFlow!).
However I can't find anything about this one.
The problem was due to a syntax error in the file smartsync.py located in the folder .repo/repo/subcmds and the from sync import Sync statement in that file.
The sync is actually referencing the file sync.py which is also located in the folder .repo/repo/subcmds and not some python file external to this body of python source code.
The from statement was missing the directory specifier of subcmds where the file sync.py is located. The line of code should have been written from subcmds.sync import Sync in order to import the class Sync from the file sync.py located in the folder subcmds. I assume this is because the python script is being run with the current directory set to .repo/repo and not .repo/repo/subcmds.
After this change was made to the file, the script ran successfully until the next error in a different file which needed to be corrected.
