Package: diffoscope
Version: 90
When comparing two NixOS iso images (one pulled from website and one I
built myself), diffoscope fails after or during printing results with
(full error included at the bottom):

It seems that diffoscope is not able to remove r-xr-xr-x temporary file:

The 'curl' seems to be first to be removed:

Non-writeable files and dirs are quite common for NixOS isos:
