- Ubuntu 16.04.2 LTS
- check the Pillow version:
pip list --format=columns | grep -i pillow
Pillow 3.1.2
- upgrade Pillow until last version:
pip install --upgrade Pillow
The headers or library files could not be found for jpeg,
a required dependency when compiling Pillow from source.
Please see the install instructions at:
https://pillow.readthedocs.io/en/latest/installation.html
I had the same compiling error that commented by @DerDanilo
On Stackoverflow there is the explanation behind the unmet pillow dependencies, like jpeg
- Upgrade Pillow unmet dependencies, here the
jpeglibraries:
apt-get install libjpeg-dev (*)
- Upgrade Pillow:
pip install --upgrade Pillow
- Check that the upgraded Pillow version is 4.1.1:
pip list --format=columns | grep -i pillow
Pillow 4.1.1

- My recommendation:
Try to install first only libjpeg-dev, if this is not enough, then install like apt-get build-dep python-imaging
Edit: After Pillow upgrade to 4.1.1 the NEW “change favicon functionality” works properly.
Thanks @lian. Like @DerDanilo suggested, the documentation should be improved or seafile integration with other distros should be improved, to avoid such glitches.
