I'm using Django 1.0.3, Apache 2.2, Python 2.5 and Ubuntu 9.04 (a recent upgrade).
When I try to delete an image (specifically I'm deleting an instance of a photo model that contains an imagefield) I get an OSError, "[Errno 1] Operation not permitted" The first thing I tried was checking the permissions in Ubuntu, they're set to allow write access for everyone. I tried to deleting the image file from an Ubuntu command line and discovered that I could do so. I tried deleting the image file from python using os.remove, that worked fine. I tried using 'python manage.py shell' and using os.remove to delete the file, that worked fine. I tried editing django/core/files/storage.py to output the results of an os.access() check to show that I did have write access to the image file immediately before attempting the os.remove. It showed that I had write access to the image file. I tried editing django/core/files/storage.py to use fcntl.lock to lock the image file (to make sure no other process had locked the image file) and it showed that the image file was not locked. I tried editing django/core/files/storage.py to use os.chmod to grant write access to the image file and got the same error message as before, only now it occured at the os.chmod() rather than at the os.remove(). I'm guessing that this problem has something to do with my recent upgrade to Django 9.04, but that's just a guess as I can't even figure out exactly what is going wrong. I would appreciate any suggestions as to what to try next. Thank you for your input.
