As a first step, can you reproduce the bug like this:

  while echo substitute 
/gnu/store/44h13hn5zssfppz67vydxcf95qsc8qfw-libreoffice-6.4.7.2 /tmp/t | guix 
substitute --substitute ; do chmod -R +w /tmp/t && rm -rf /tmp/t; done

?

FWIW, I can’t seem to reproduce it with:

--8<---------------cut here---------------start------------->8---
$ guix describe
