       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 pack‐
       ages. To accomplish this, it may update some packages that are  already
       installed, or install additional packages. To prevent 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 pre‐
       vent additional dependency packages from being installed.

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

OPTIONS
   positional arguments:
       package_spec
              Packages to 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),  implies
              --no-deps.

       --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 dependencies.

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

       --use-index-cache
              Use cache of channel index files.

       --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 (in envs dirs).

       -p PATH, --prefix PATH
              Full  path   to   environment   prefix   (default:   root   pre‐
              fix/envs/build-environment).

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

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

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

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

       --alt-hint
              Use an alternate algorithm to generate an unsatisfiability hint.

       --update-dependencies, --update-deps
              Update dependencies (default: True).

       --no-update-dependencies, --no-update-deps
              Don't update dependencies (default: False).

       --channel-priority, --channel-pri, --chan-pri
              Channel priority takes precedence over package version (default:
              True).  Note: This feature is in beta and may change in a future
              release.

       --no-channel-priority, --no-channel-pri, --no-chan-pri
              Package version takes precedence over channel priority (default:
              False). Note: This feature is in beta and may change in a future
              release.

       --show-channel-urls
              Show channel urls (default: True).

       --no-show-channel-urls
              Don't show channel urls.

       --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.
