Conda package broken
The conda package is broken. On Ubuntu 18.04, conda 4.8.3 and Python 3.7 and 3.8 environments, the command
conda install -c orfeotoolbox otb leads :
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 the existing python installation in your environment: Specifications: - otb -> python[version='>=2.7,<2.8.0a0|>=3.6,<3.7.0a0|>=3.5,<3.6.0a0'] Your python: python=3.7 If python is on the left-most side of the chain, that's the version you've asked for. When python appears to the right, that indicates that the thing on the left is somehow not available for the python version you are constrained to. Note that conda will not change your python version to a different minor version unless you explicitly specify that.
Also reproduced on Ubuntu Virtual Machine. See this forum post
