I am running into the same issue. Even when running conda update conda --all in my base environment, it prints out the same warning given by dfm794 above. As mention by them, when running the suggested update command (conda update -n base -c defaults conda) nothing happens other than the warning being given again
Can you try to instead of conda update, but run the command conda install conda=<exact version you want>. For example conda install conda=24.3.0
It might take a couple of seconds to a minute since if your conda for example 22.9.0 and need the newest which is conda 24.9.1. The installation time might take sometime
But if the command above doesn’t work, I would recommend to do a fresh uninstall and reinstall of Anaconda if possible with the links below:
Also I found a bit more information on why conda update might not be working. It is cause conda update command is trying to update conda without being outside the boundaries of your other dependancies. So if conda 22.9.0 has a package that won’t work if it is conda 23.1.0 it won’t update past that version.
My example output for running conda install conda=24.3.0 when I had version 23.1.0. Hopefully you get the same result, but if not uninstalling and reinstalling fresh might be a work around.
After encountering the same problem as @dfm794 with:
‘conda update -n base -c defaults condo’
in order to update from conda version 24.11.3 → 25.9.1 and verifying with conda –version that 24.11.3 was indeed still installed I tried conda update conda –all and the update to 25.9.1 is in progress. This is on an enterprise installation of Ubuntu Linux 6.8.0, if that is of interest.
