How to force conda to upgrade all packages, regardless of dependency graph?

Question

I usually end up with a bunch of out-of-date packages in my conda environment because some package I installed at one time has a pinned dependency (e.g. scipy == 0.15.0) and it prevents other packages (e.g. jupyter) from updating. How can I ignore the pins and force update all packages?

Answer 1

conda update --all --no-pin --no-channel-priority

This ignores all pinned packages, channel priority, and updates everything. Beware that this might break compatibility for some packages that really need a specific version of a package.
