@polpoman, the avif thing will just need installing as any other package, however there is currently no AUR package for it unfortunately.

The PDF thing is apparently part of qt6-webengine, so you may need to install that first. I'll put it in the opt-deps.

Also is this a normal error? Is there a way to make the import work?

v544, 2023/09/21 15:14:32: If this information helps, QtPdf failed to import because:

Hydrus gives me this message, when importing avif files.

"Sorry, you need the pillow-heif library to support this filetype (avif)! Please rebuild your venv."

How do I do that? I have downloaded the from the project github, but where should I execute it? I can't find the venv folder that the AUR install uses.

Since missing offline docs now no longer triggers any serious issues with the context help system, I've removed the hard dependency on doc files of some sort being present in the hydrus directory and as a consequence have deprecated the dummy docs package. So don't worry about that going: the hydrus and hydrus-docs packages are now separate from each other and the default experience the average user gets if they forget to install the docs is acceptable and no longer simply looks like a bug in hydrus or the package.

I had a similar issue as to simona, but with building the hydrus-docs dependency; ModuleNotFound RE: python-mergedeep. Indeed, the issue was with its AUR-bared python dependencies not having rebuilt for Python 3.11. However, not only did I have to remove downstream Python dependencies built from AUR, but also clear the build and package cache to force a clean build on re-install.

Simona, please run this script and reinstall any AUR packages it mentions:

Since svg support was added recently (, you now need the qt6-svg package otherwise hydrus-client will fail to start with this error:

Traceback (most recent call last):
  File "/opt/hydrus/hydrus/", line 24, in <module>
    from hydrus.client.gui import QtInit
  File "/opt/hydrus/hydrus/client/gui/", line 142, in <module>
    from qtpy import QtSvg
  File "/usr/lib/python3.11/site-packages/qtpy/", line 15, in <module>
    from PyQt6.QtSvg import *
ImportError: cannot open shared object file: No such file or directory

Critical boot error occurred! Details written to hydrus_crash.log in either db dir or user dir!

Thanks for the tip, I've confirmed the same on my own machine & added that to the list of required dependencies
