"anaconda" is a metapackage that pins a bunch of packages to a fixed
version. So "conda update anaconda" is asking to "updgrade" to the latest
version of the metapackage, which might in turn lead to a downgrade of many
individual "real" packages if you have updated those packages individually
since you last updated the anaconda metapackage.
