Changed files: projects/pillow/Dockerfile
Please add an "apt-get update" before "apt-get install". Otherwise, a cached and outdated RUN layer may lead to install failures.
Failed.

Hmm. I would have thought that is what is happening?

@radarhere I think that check is failing because of the install at the bottom of the file:

Also, thanks for investigating the failure in #12027!

Out of curiosity, did the changes here work for you locally?

Part of the changes I propose in that PR are aliasing the python3 and python executables in the base images and last I checked, only python3 was available in the currently deployed images.

If it turns out that this does depends on the unmerged changes:

I've been collecting patches that will be required after a Python 3.10 upgrade on a per broken project basis here: master...DaveLak:oss-fuzz:update-projects-after-python-10-upgrade and that includes Pillow's, dcd020c

You're right, thanks - I've pushed a commit, and presubmit checks are satisfied now.

I reckon the CI failed due to incompatible python version?

ERROR: Package 'pillow' requires a different Python: 3.8.3 not in '>=3.9'
ERROR:__main__:Building fuzzers failed.

Pillow dropped support for Python 3.8, so the error is already happening in master.

This PR isn't intended to fix Pillow's oss-fuzz completely, merely to try and help the final solution of #12027.

Yep, I will merge, then
