For reference, this is has info on the Python 2 version on many
popular software repositories:

https://repology.org/metapackage/python2/versions

I did this to check for repositories that don't have any 2.7 package:

  $ curl -s 'https://repology.org/api/v1/metapackage/python2' | \
    jq -r 'group_by(.repo) | .[] | "\(.[0].repo): \(map(.version))"' | \
    grep -v '"2\.7'
  centos_6: ["2.6.6"]
  maemo_fremantle: ["2.5.4","2.5.4","2.5.4","2.5.4"]
  rosa_server_6_9: ["2.6.6"]
