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 ?

Answers:

If you need to update all packages, the command is:.

conda update --all
Answered By: cosmoscalibur
conda clean --all
conda update --all

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

You don’t need to update conda, particularly if you are using an HPC cluster conda so you don’t have write permissions. You only need to clean any previously failed installations with

conda clean --all
