Anaconda Cloud - Updating packages

Hi, I am new to Anaconda Cloud. There are 4 kernels, 2 of which I use most. For one kernel anaconda-2022.05-py39, how do I update a package, such as seaborn? I opened a console in that kernel and entered “conda install matplotlib==3.5.2” and get the following with the process never ending:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Is it possible to update packages in Anaconda Cloud? Also is it possible to load a yaml environment file?
thanks!
