Backport of DIRACGrid#8876: the ubuntu-latest runner images no longer ship conda on the PATH, so the PilotWrapper jobs fail with 'conda: command not found' on every PR (runner image ubuntu26/20261101). Install Miniforge explicitly with conda-incubator/setup-miniconda before the steps that rely on it; python 3.6.8 becomes 3.6.9, the nearest build on conda-forge, and the unused 'free' channel is dropped. The CVMFS deployment workflows and the pylint-py27 job get the same treatment. The Pilot artifacts are downloaded with 'gh run download', avoiding the rate-limit flakiness of the unauthenticated API call.

CI fix: install conda explicitly in the workflows that need it (backport of #8876 to rel-v9r0)
The
PilotWrapperjobs (and the CVMFS deployment workflows) fail on every PR with:The
ubuntu-latestrunner images no longer shipcondaon the PATH (imageubuntu26/20261101), while the workflow assumes it is preinstalled. This is the backport of #8876 (merged intointegration) torel-v9r0.Changes, identical to the integrated fix:
pilotWrapper.yml: install Miniforge explicitly withconda-incubator/setup-miniconda@v3before the steps that rely on conda (Miniforge rather than Miniconda per the review of ci: install conda explicitly in the workflows that need it #8876: thedefaultschannel carries Anaconda ToS licensing requirements);3.6.8→3.6.9— the exact 3.6.8 build only exists in thedefaultschannel, which Miniforge deliberately does not use; 3.6.9 is the nearest build on conda-forge;conda createdrops the unusedfreechannel;cvmfs.yml/deployment.yml(where present on this branch): sameInstall condastep for theworkflow_dispatch-only CVMFS deployment jobs.integrationin chore: authenticate the artifacts API call in the PilotWrapper workflow #8879).Evidence
integration: PR ci: install conda explicitly in the workflows that need it #8876 went from 6 PilotWrapper failures (conda: command not foundon every job) to all 6 legs passing, including the 3.6.9 legs.Merge Danger
Door: two-way — one workflow step added; CI-only, no product code.
Blast Radius: CI only.
