       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.

OPTIONS
   positional arguments:
       package_spec
              Packages to install or update in the conda environment.

   optional arguments:
       -h, --help
              Show this help message and exit.

       -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.
