   Updates conda packages to the latest compatible version.

          This command accepts a list of package names and updates them to
          the latest versions that are compatible with all other  packages
          in the environment.

          Conda  attempts  to install the newest versions of the requested
          packages. To accomplish this, it may update some  packages  that
          are  already  installed, or install additional packages. To pre‐
          vent existing packages from updating, use  the  --no-update-deps
          option.  This  may  force conda to install older versions of the
          requested packages, and it does not  prevent  additional  depen‐
          dency packages from being installed.

          If  you  wish  to  skip  dependency checking altogether, use the
          '--force' option. This may result in an environment with  incom‐
          patible  packages,  so  this option must be used with great cau‐
          tion.

   -y, --yes
          Do not ask for confirmation.

   --dry-run
          Only display what would have been done.

   -f, --force
          Force install (even when package already installed).

   --file FILE
          Read package versions from the given file. Repeated file  speci‐
          fications can be passed (e.g. --file=file1 --file=file2).

   --no-deps
          Do  not  install,  update,  remove, or change dependencies. This
          WILL lead to broken environments and inconsistent behavior.  Use
          at your own risk.

   --only-deps
          Only install dependencies.

   -m, --mkdir
          Create the environment directory if necessary.

   -C, --use-index-cache
          Use cache of channel index files, even if it has expired.

   --use-local
          Use locally built packages.

   --offline
          Offline mode, don't connect to the Internet.

   --no-pin
          Ignore pinned file.

   -c CHANNEL, --channel CHANNEL
          Additional  channel  to  search  for  packages.  These  are URLs
          searched in the order they  are  given  (including  file://  for
          local directories). Then, the defaults or channels from .condarc
          are searched (unless --override-channels is given). You can  use
          'defaults'  to  get the default packages for conda, and 'system'
          to get the system  packages,  which  also  takes  .condarc  into
          account.  You  can  also  use  any  name  and the .condarc chan‐
          nel_alias value will be prepended. The default channel_alias  is
          http://conda.anaconda.org/.

   --override-channels
          Do not search default or .condarc channels. Requires --channel.

   -n ENVIRONMENT, --name ENVIRONMENT
          Name of environment.

   -p PATH, --prefix PATH
          Full path to environment prefix.

   -q, --quiet
          Do not display progress bar.

   --copy Install all packages using copies instead of hard- or soft-link‐
          ing.

   -k, --insecure
          Allow conda to perform "insecure" SSL connections and transfers.
          Equivalent to setting 'ssl_verify' to 'false'.

   --update-dependencies, --update-deps
          Update  dependencies. Overrides the value given by `conda config
          --show update_deps`.

   --no-update-dependencies, --no-update-deps
          Don't update dependencies. Overrides the value given  by  `conda
          config --show update_deps`.

   --channel-priority, --channel-pri, --chan-pri
          Channel  priority  takes  precedence over package version. Over‐
          rides the value given by `conda config --show channel_priority`.

   --no-channel-priority, --no-channel-pri, --no-chan-pri
          Package version takes precedence over  channel  priority.  Over‐
          rides the value given by `conda config --show channel_priority`.

   --clobber
          Allow  clobbering of overlapping file paths within packages, and
          suppress related warnings.

   --show-channel-urls
          Show channel urls. Overrides the value given  by  `conda  config
          --show show_channel_urls`.

   --no-show-channel-urls
          Don't  show  channel  urls.  Overrides the value given by `conda
          config --show show_channel_urls`.

   --download-only
          Solve an environment and ensure package  caches  are  populated,
          but  exit  prior to unlinking and linking packages into the pre‐
          fix.

   --json Report all output as json. Suitable for using conda programmati‐
          cally.

   --debug
          Show debug output.

   --verbose, -v
          Use once for info, twice for debug, three times for trace.

   --all  Update all installed packages in the environment.
