title: Unable to install anaconda on OS Catalina after changing username
body: <p>I upgraded my OS to Catalina then anaconda didn't work, so I deleted it and wanted to install it again.</p>
  
  <p>However, my macOS username was <em>zoyie 1</em> which contains a space, leading to fail of installation. </p>
  
  <p>Then I changed my username from <em>zoyie 1</em> to <em>ZongyuWu</em> and installed again.</p>
  
  <p>The 64-Bit Graphical Installer still didn't work and gives me no error information, so I tried the 64-Bit Command Line Installer and get</p>
  
  <pre><code>Collecting package metadata (current_repodata.json): failed
  
  UnavailableInvalidChannel: The channel is not accessible or is invalid.
    channel name: Downloads
    channel url: file:///Users/zoyie 1/Downloads
    error code: 404
  
  You will need to adjust your conda configuration to proceed.
  Use `conda config --show channels` to view your configuration's current state,
  and use `conda config --show-sources` to view config file locations.
  
  As of conda 4.3, a valid channel must contain a `noarch/repodata.json` and
  associated `noarch/repodata.json.bz2` file, even if `noarch/repodata.json` is
  empty. Use `conda index /Users/zoyie 1/Downloads`, or create `noarch/repodata.json`
  and associated `noarch/repodata.json.bz2`.

  <p>Does anyone know how to install anaconda on my mac now?</p>
  
  <p>I can't use conda since I haven't installed anaconda.</p>
  
  <p>I can't find ~/.condarac since I haven't installed anaconda.</p>
  
  <p>There is no use by deleting lines about conda in ~/.bash_profile.</p>
  
  <p>Same problem when trying to install miniconda.</p>
