Is there a way to run the QGIS-editor through Pycharm? QGIS offers a nice set of functions to analyze raster files. For example zonalstatisticsfb calculates the zonal stats of a raster file:
import processing
rasterfile = '/home/iliamous/PycharmProjects/winbank/indicators/tmean/rcp_2_6/cnrm_cerfacs_cm5_r1i1p1_knmi_racmo22e/tmean_rcp26_CNRM-CERFACS-CNRM-CM5_KNMI-RACMO22E_r1i1p1_20210101-20301231.tiff'
shapefile = '/home/iliamous/PycharmProjects/winbank/tk_egsa_dissolved/tk_egsa_disolved.shp'
ofile = '/home/iliamous/PycharmProjects/winbank/zonal_stats.csv'
processing.run("native:zonalstatisticsfb",
{'INPUT':shapefile,
'INPUT_RASTER':rasterfile,
'RASTER_BAND':1,
'COLUMN_PREFIX':'_',
'STATISTICS':[0,2],
'OUTPUT':ofile})
The QGIS editor though lacks important features of the Pycharm editor like debugging. I was wondering if there is a way to run QGIS-editor through Pycharm. There is a lot of information online on how to do that, but it is mostly for Windows and fuzzy for Ubuntu.
My first though was to bypass this entire process by downloading the qgis package that includes the processing function. To do so, I followed the instructions on https://anaconda.org/conda-forge/qgis but it threw at me the following error:

An unexpected error has occurred. Conda has prepared the above report.

Would you like conda to send this report to the core maintainers? [y/N]:
Timeout reached. No report sent.
Preferably I would like someone to help me use the QGIS-editor through Pycharm. If this is not possible, to point me to some qgis package to install and use through Pycharm. My setup is Ubuntu 22.04.2 LTS, QGIS 3.22.7-Białowieża, PyCharm 2023.1 (Community Edition).
I solved the problem. To do so, I installed QGIS from source, following the instructions from https://github.com/qgis/QGIS/blob/master/INSTALL.md#3-building-on-gnulinux.
Then, I set up Pycharm for QGIS debugging following the instructions from https://docs.qgis.org/testing/en/docs/pyqgis_developer_cookbook/plugins/ide_debugging.html?highlight=pycharm.
