[1][2]related to this, it seems we can't blindly return in all cases. On changing, the lcopy as below, install appears
tobe working.

I am not able to reproduce this issue on HEAD. Seems like the
following git-commit fixes it,
commit 01deec5f8ae64b5120cc8c93d54fe0e19e477b02
Author: Andrew Dunstan <andrew@dunslane.net>
Date: Mon May 28 16:44:13 2018 -0400
Return a value from Install.pm's lcopy function
Commit 3a7cc727c was a little over eager about adding an explicit return
to this function, whose value is checked in most call sites. This change
reverses that and returns the expected value explicitly. It also adds a
check to the one call site lacking one.
