The problem comes from the fac that pillow is built without jpeg support, see the file SAGE_ROOT/build/pkgs/pillow/spkg-install : https://git.sagemath.org/sage.git/tree/build/pkgs/pillow/spkg-install

If you want to fix the issue, and if you built Sage from source, you can :

  • install the (ubuntu) package libjpeg-dev
  • remove the line --disable-jpeg \ line in SAGE_ROOT/build/pkgs/pillow/spkg-install
  • recompile pillow with sage -f pillow
