running a user code like QE with root privileges is not a great idea.
Nothing nasty should happen, but if it does, your machine is at risk.

if the code says that "/some/nonexistent/or/nonwritable/directory/"
is nonexistent or not writable, it is nonexistent or non writable.
The code reprints the full directory name so that one can easily
check what is wrong, for instance issuing commands
"ls /some/nonexistent/or/nonwritable/directory/" or
"touch /some/nonexistent/or/nonwritable/directory/any-file-name".
In most cases, it is just a misspell.
