<div style="font-family: Arial, sans-serif; font-size: 16px;">Thanks for your help, but the qca version does not seem to be the problem. I tried to create new environments using the version of qca you suggested, and also several older versions (all seem to be using qt5), but the crash is still happening.</div><div style="font-family: Arial, sans-serif; font-size: 16px;"><br></div><div style="font-family: Arial, sans-serif; font-size: 16px;">In a Mint 22 VM I was able to setup the conda env, and qgis starts up fine. And on another laptop running Debian 12 no prob. So it must be something different with Debian 13.</div><div style="font-family: Arial, sans-serif; font-size: 16px;"><br></div><div style="font-family: Arial, sans-serif; font-size: 16px;">Best, Micha</div><div style="font-family: Arial, sans-serif; font-size: 16px;"><br></div>

Hi <br>
<br>
I just installed similar on linux mint. The default qca dependency
is wired to QT6. But QGIS 3.4 is still on QT5. So you need a
specific version of qca which has dependencies to QT5. Well, that is
what claude told me. For me the following works:
<ol data-listchain="__List_Chain_75">
<li><font face="monospace">conda create -n qgis-344_py313 -c
conda-forge qgis=3.44.9 python=3.13.14 "qca=2.3.10=h71e8f01_0"
-y </font></li>
<li><font face="monospace">conda activate qgis-344_py313</font></li>
<li><font face="monospace">conda run qgis</font></li>
</ol>
Hope this helps<br>

that the native QGIS.org *.deb installed on this

<div style="font-family: Arial, sans-serif; font-size: 16px;">I'd like to
have the conda installation working since the EnMAPbox
plugin requires certain python packages that are not
available in Debian. So the EnMAPbox devs recommend to
setup the conda environment.</div>
