Hi everyone,

I have had problem when I have wanted to install ros-noetic.

Distributor ID: Ubuntu Description: Ubuntu 20.04.5 LTS Release: 20.04

I have run the following commands

conda create -n ros python==3.9

conda activate ros

conda config --env --add channels conda-forge

conda config --env --add channels robostack-staging

conda config --env --remove channels defaults

conda install ros-noetic-desktop

And I get this error:

**_Collecting package metadata (current_repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source. Collecting package metadata (repodata.json): done Solving environment: failed with initial frozen solve. Retrying with flexible solve. Solving environment: / Found conflicts! Looking for incompatible packages. This can take several minutes. Press CTRL-C to abort. failed

UnsatisfiableError: The following specifications were found to be incompatible with each other:

Can anybody help me please?

Thanks

feel free to reopen if still doesn’t work

Thank you Tobias for your quick response. The only two differences I see compared to the steps in the official guide are:

- I use conda instead of mamba, is there a difference between mamba and conda?
- I specify a specific Python version, is there any issue with specifying the Python version when creating the environment?

Yes - mamba can resolve large environments like those of RoboStack, while conda struggles (see your error ..). And yes, unfortunately RoboStack requires a particular version of Python.
