conda update anaconda Fails | ClobberError

Question

I am trying to update all conda packages.

Tried running these command

conda update anaconda

conda update --all

But getting this error after confirming on most of the packages.

How to solve and update all the packages ?

Answer 1

conda clean --all
conda update --all

Worked for me. I needed to run update command multiple times to update all packages.
