Apt installs python3-pil when asked to install python3-pillow #252

Closed ChrisHodgesUK closed 4 months ago

ChrisHodgesUK commented 4 months ago

Describe the bug

Pillow has capabilities that PIL doesn't, in my case ImageTk. However (even after removing python3-pil with apt), it's not possible to install pillow. The failure is rather subtle because it claims a successful installation, but buried in the installation output is Note, selecting 'python3-pil' instead of 'python3-pillow', and sure enough I get the same ImportError: cannot import name 'ImageTk' from 'PIL' when I try to use pillow.

It should install the package I asked for, not guess at a lesser substitute. If there's a good reason not to install the package I wanted, it should throw an error at installation, not sneakily install something else

Steps to reproduce the behaviour

sudo apt remove python3-pil sudo apt install python3-pillow

To confirm: python >>> from PIL import ImageTk

Moved to bookworm-feedback repo as this issue has nothing to do with linux kernel.

It doesn't have anything to do without anything we've done with bookworm either. The issue should be taken up with Debian and they will have good reasons they've decided to do it this way.

Taking a closer look, python3-pil IS pillow and the ImageTk bit comes from the python3-pil.imagetk package.

More subtle than I (could have) guessed, which also makes for a pretty simple workaround. The different packaging such that Pillow (deb) is a subset of Pillow (via pip) still doesn't seem like sensible/expected behaviour.

Oops, sorry. The link I followed didn't make that clear. Thanks for moving it.

@ChrisHodgesUK what link did you follow?

Sounds like the initial issue has been resolved, so I'm going to close this. Any further action will need to fall on Debian's shoulders. Feel free to continue discussion in this closed issue though!
