Dear QGIS community, I have two questions : Do you know how to install easily pcraster on ubuntu ? How can I uninstall the latest version of QGIS 3.24 and get an older version of QGIS on ubuntu ?
Situation : I am a recent ubuntu user and I need to install pcraster for advanced watershed calculations. Apparently it is possible to install it using anaconda-navigator, so I first needed to install anaconda using this tutorial : https://gisunchained.wordpress.com/2019/05/29/using-qgis-from-conda/. But once QGIS 3.18.3 installed and opened, any plugin utilization do not work at all. For example, applying strahler order tool from SAGA on a DEM does not work. Every time, the python error is : WARNING Traceback (most recent call last): File "/home/raphael/anaconda3/envs/demonstration/share/qgis/python/plugins/processing/gui/AlgorithmDialog.py", line 194, in runAlgorithm self.cancelButton().setEnabled(self.algorithm().flags() & QgsProcessingAlgorithm.FlagCanCancel) TypeError: setEnabled(self, bool): argument 1 has unexpected type 'Flags' Thus I tried to install QGIS 3.24 via this link https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu to see if the problem can be resolved with a more recent version. The problem is that this tutorial is not for a conda environment, so now I want to uninstall 3.24 to go to an older and more stable version and I don't know how to do it. If I install and uninstall QGIS, the version 3.24 still appears. Moreover, I still don't have pcraster installed and operational which I need the most. Thank you in advance for your precious answer and have a good night! Raphaël
