Hi All,

I need to have a Docker image that runs Anaconda3 + Jupyterlab + Jupyterhub. I have following versions:

- Anaconda3-2022.10-Linux-x86\_64
- Jupyterhub v 4.0.2
- JupyterLab v3.4.4

The problem is that I cannot update JupyterLab to more recent version, at least 3.6.6.

If I do just:  
conda install -c conda-forge jupyterlab\>=3.6.3, then I get version 3.6.6.

If I do:  
conda install -c conda-forge jupyterhub jupyterlab\>=3.6.3, then I get version 3.4.4.

Updating jupyterlab as:  
conda update-c conda-forge jupyterlab\>=3.6.3 takes huge amount of time and finally through errors.

Spent already couple of days googling and building new docker image and got 0 progress. Thanks in advance for any help.

Regards  
Eugen

Try using mamba instead of conda [https://anaconda.org/conda-forge/mamba](https://anaconda.org/conda-forge/mamba)  
It tends to be faster, and the error messages are usually more informative.
