7.12 to 8.x: step: install-portability | status: failed

I carefully followed these instructions:

https://pre-release.docs.suitecrm.com/8.x/admin/installation-guide/legacy-migration/

However, I come upon the same roadblock each time. During part 2.4 of the tutorial, and specifically the “.htaccess” section:

2023-02-24_09-17-26 - TechSmith Screencast - TechSmith Screencast

Iget the following error:

step: install-portability | status: failed
Not able to find/read the folder to copy ‘/home/sitoinre/public_html/MYFOLDERNAME/suitecrm8/tmp/package/upgrade/legacy-migration/include/portability’

It would seem that there is no “tmp” directory that the installer is looking for. And I am certain I am running the installer in the correct directory, as the “suitecrm8” directory is the only one which has a “bin” directory in it. The “bin” directory is required, since it is part of the upgrade command:

./bin/console suitecrm:app:setup-legacy-migration

Without it, the system tells me that it can’t find it, and the script can’t run.
