We have several issues (e.g. #14181) where the installer occasionally fails in the postinstall script for unknown causes, on some hosts.
This seems to be sometimes the culpable section and this patch should help trace the issue or alleviate the common symptoms of it (see #14181)
Backport of #15213.
