          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 <B>--no-update-deps</B> 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.

          <B>-f</B>, <B>--force</B>
                 Force install (even when  package  already  installed),  implies
                 <B>--no-deps</B>.
   
          <B>--file</B> FILE
                 Read  package versions from the given file. Repeated file speci-
                 fications can be passed (e.g. <B>--file</B>=<I>file1</I> <B>--file</B>=<I>file2</I>).
   
          <B>--no-deps</B>
                 Do not install dependencies.
   
          <B>-m</B>, <B>--mkdir</B>
                 Create the environment directory if necessary.
   
          <B>--use-index-cache</B>
                 Use cache of channel index files.
   
          <B>--use-local</B>
                 Use locally built packages.
   
          <B>--offline</B>
                 Offline mode, don't connect to the Internet.
   
          <B>--no-pin</B>
                 Ignore pinned file.
   
          <B>-c</B> CHANNEL, <B>--channel</B> 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 <B>--override-channels</B> 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/.
   
          <B>--override-channels</B>
                 Do not search default or .condarc channels. Requires  <B>--channel</B>.
   
          <B>-n</B> ENVIRONMENT, <B>--name</B> ENVIRONMENT
                 Name      of      environment      (in      <I>root</I>     <I>prefix/envs</I>
                 :/Users/wwarner/.conda/envs).
   
          <B>-p</B> PATH, <B>--prefix</B> PATH
                 Full path to environment prefix (default: <I>default</I> <I>prefix</I>).

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

                 Use an alternate algorithm to generate an unsatisfiability hint.
