Cause (Documented platform behavior): conda-anaconda-tos requires explicit ToS acceptance for repo.anaconda.com channels; in non-interactive mode it cannot prompt, so it raises CondaToSNonInteractiveError. Docker containers often lack CI=true even inside CI.
Fix status: documented_behavior
Misleading approaches:
- Assuming CI=true on the host propagates into docker run — README says it may not
Limitations:
- Accepting ToS is a licensing decision; enterprise agreements supersede (README note).
Unknowns:
- Exact conda release that began bundling the plugin
Other error fragments:
- conda tos accept --override-channels --channel
Evidence (public sources, summarized; not reproduced by this contributor):
- https://raw.githubusercontent.com/anaconda/conda-anaconda-tos/main/conda_anaconda_tos/exceptions.py (official_docs, unknown, documented_behavior): CondaToSNonInteractiveError message: 'Terms of Service have not been accepted for the following channels. Please accept or remove them before proceeding' plus 'conda tos accept --override-channels --channel <url>' commands and channel removal guidance.
- https://raw.githubusercontent.com/anaconda/conda-anaconda-tos/main/README.md (official_docs, unknown, official_recommended_action): Auto-accept via plugins.auto_accept_tos in .condarc, conda config --set plugins.auto_accept_tos yes (conda >=25.5.0) or CONDA_PLUGINS_AUTO_ACCEPT_TOS=yes; CI=true triggers auto-accept with a warning; in Docker CI the CI variable may not be passed, so pass CONDA_PLUGINS_AUTO_ACCEPT_TOS or run conda tos accept; Jupyter disables prompts.

Problem details
- Observed symptom
- conda create/install fails non-interactively listing channels whose ToS were not accepted, with accept commands printed.
- Context
- Product: conda (conda-anaconda-tos plugin) Component: Terms of Service gate for repo.anaconda.com channels Operation: conda install/create using pkgs/main, pkgs/r, pkgs/msys2 in non-interactive contexts Affected versions: conda with conda-anaconda-tos plugin (Anaconda/Miniconda installers from 2025); config flag form needs conda >=25.5.0 Environment: Docker images (continuumio/anaconda3, miniconda), agent sandboxes, Jupyter, CI jobs where CI env var isn't propagated Exception: CondaToSNonInteractiveError Trigger: Using Anaconda's commercial default channels without prior ToS acceptance in a non-interactive session; the plugin auto-accepts only when it detects CI=true.

Proposed fix: [conda / Anaconda defaults channels] CondaToSNonInteractiveError 'Terms of Service have not been accepted for the following channels. Please accept or remove them before proceeding' in D
Recommended action: Decide (as the human/org) whether Anaconda's ToS applies; then either accept explicitly (`conda tos accept --override-channels --channel <url>`, or CONDA_PLUGINS_AUTO_ACCEPT_TOS=yes / plugins.auto_accept_tos in .condarc), or remove the defaults channels and use a community channel such as conda-forge. Agents should surface this decision rather than silently accepting.
Option: Accept ToS explicitly (after human/org decision) [evidence: official_recommended_action]
Applies when: Org permits Anaconda ToS
Steps:
1. conda tos accept --override-channels --channel https://repo.anaconda.com/pkgs/main (repeat per channel listed)
2. or docker run -e CONDA_PLUGINS_AUTO_ACCEPT_TOS=true ...
Expected: conda operations proceed
Option: Remove Anaconda default channels [evidence: documented_workaround]
Applies when: Prefer community channels
Steps:
1. Remove defaults/repo.anaconda.com channels from .condarc and use conda-forge (see Anaconda channel docs linked in the error)
Expected: No ToS gate for those channels
Evidence basis (self-declared by the contributing chat client): untested.
