I am getting an error recently.

ImportError: pusimp has detected the following problems with dolfinx dependencies:
1) Dependencies imported from a local path rather than from the path provided by apt:
* ufl was imported from a local path: expected in /usr/lib/python3/dist-packages/ufl/__init__.py, but imported from /home/bagla0/.local/lib/python3.10/site-packages/fenics_ufl-2019.1.0-py3.10.egg/ufl/__init__.py.

pusimp suggests to apply all of the following fixes:
1) To uninstall local dependencies:
* run 'pip uninstall fenics-ufl' in a terminal, and verify that you are prompted to confirm removal of files in /home/bagla0/.local/lib/python3.10/site-packages/fenics_ufl-2019.1.0-py3.10.egg/ufl. 

You can disable this check by exporting the DOLFINX_ALLOW_USER_SITE_IMPORTS environment variable. Note, however, that this may break the installation provided by apt.
If you believe that this message appears incorrectly, report this at https://fenicsproject.discourse.group/ .

I have uninstalled using pip uninstall fenics-ufl in terminal, but, the error remains same. I don’t know what wrong I did. I remember, I updated the doflinx only. I also reinstalled fenicsx in my ubuntu, but, it doesn’t work

The error says it all. You need to get rid of /home/bagla0/.local/lib/python3.10/site-packages/fenics_ufl-2019.1.0-py3.10.egg, which would hide the apt installation of ufl.

pip uninstall fenics-ufl

should be the way to uninstall it cleanly. What do you get when running it? Worst case scenario you can simply remove the folder :wink:
