title: On certain conda commands error: 'Image not found'
body: <p>These error messages may have been caused by an Xcode update I just did recently but I am not sure. I'm running MacOS 10.15.4.</p>
  
  <p>This is the error I receive upon running <code>conda info</code> in my terminal.</p>

  <p>I am getting similar error reports upon running <code>conda env list</code>, but not <code>conda list</code>.
  I have the normal anaconda3 distribution and have not seen issues like this with anaconda before. I think I can just wipe the install directory at <code>~/opt</code> but I would rather not have to redo all my settings. I've seen similar issues like <a href="https://github.com/conda/conda/issues/6183" rel="nofollow noreferrer">https://github.com/conda/conda/issues/6183</a> but their solutions did not work for me despite the similar situation (I tried running the <code>conda update -c rdonnellyr -c main --all</code> command.</p>
