Hello
I updated my guix system and qutebrowser does not work since then.
When I try to run qutebrowser I get the following error pop-up:


Fatal error: PyQt6.QtCore is required to run qutebrowser but could 
not be imported! Maybe it's not installed?
The error encountered was: libzstd.so.1: cannot open shared object 
file: No such file or directory
Please search for the python3 version of Python3 version of 
PyQt6.QtCore in your distributions packages, or see 
https://github.com/qutebrowser/qutebrowser/blob/main/doc/install.asciidoc
If you installed a qutebrowser package for your distribution, 
please report this as a bug.
Qt wrapper info:
PyQt6: success
PyQt5: not imported
-> selected: PyQt6 (via autoselect)

Hi!

I tried running qutebrowser on the following Guix

>   guix da94cd1
>   repository URL: https://git.savannah.gnu.org/git/guix.git
>   branch: master
>   commit: da94cd1ea69559a80d291c6a574b0f23e30c64f2

Running with the following command in pure container:

> guix shell --pure -CN -E "^DISPLAY$" -E "^XAUTHORITY$"
> --expose="$XAUTHORITY" --share=/tmp/.X11-unix/ qutebrowser bash --
> bash -c "LIBGL_ALWAYS_SOFTWARE=1 qutebrowser"

Qutebrowser starts successfully and opens the default search engine page.

In your error I find odd the following line:
> The error encountered was: libzstd.so.1: cannot open shared object

Maybe there is something wrong with the store?

I am not an expert there, but you could try:

> sudo guix gc --verify=repair

Hello

Problem was that PyQt6 couldn't load libzstd.so.1 so Qutebrowser 
couldn't start.
It was due to pyqt6 installed from pip.
I removed pyqt6 installed from pip and now qutebrowser works fine.

Thank you
Best
