title: Solving environment: failed with current_repodata.json, will retry with next repodata source. Conda Fails to Create a new env
body: <p>** Conda Fails to Create a new env: stuck at &quot;Executing transaction&quot;**</p>
  <p>I am working with a MacOS, BigSur 11.6, and have updated conda and mamba</p>
  <p><code>conda update --all</code></p>
  <p><code>conda update mamba</code></p>
  <p>and, following guidance from a <a href="https://github.com/fermi-lat/Fermitools-conda/wiki/Quickstart-Guide" rel="nofollow noreferrer">software installation guide</a> I tried to create a new env:</p>
  <p><code>conda create -n fermi -c conda-forge -c fermi fermitools python=3 clhep=2.4.4.1</code></p>
  <p>Also tried with the dev version:</p>
  <p><code>conda create -n fermi-2.0.24 -c conda-forge -c fermi/label/dev fermitools=2.0.24</code></p>
  <p>and with mamba</p>
  <p><code>mamba create -n fermi -c conda-forge -c fermi fermitools python=3 clhep=2.4.4.1</code></p>
  <p>All trials get stuck in &quot; executing transaction \ &quot; (&gt; 1h)</p>
  <p>when hitting ctrl+c, all trials show the same error msg:</p>
  <p>&quot; ERROR conda.core.link:_execute(699): An error occurred while installing package 'conda-forge::gdk-pixbuf-2.42.6-h2e6141f_0'. &quot;
  &quot; Rolling back transaction: done &quot;</p>
  <p>my <code>uname -v:</code></p>
  <p>Darwin Kernel Version 20.6.0: Mon Aug 30 06:12:21 PDT 2021; root:xnu-7195.141.6~3/RELEASE_X86_64</p>
  <p>my <code>conda --version</code></p>
  <p>conda 4.10.3</p>
  <p>There seems to be a long standing discussion about similar issues <a href="https://github.com/conda/conda/issues/6986" rel="nofollow noreferrer">here</a>. Some argue that hitting &quot;enter&quot; solved the problem after &quot; executing transaction \ &quot; was running for a long time. It would be great, but did not worked.</p>
  <p>The issue <a href="https://github.com/conda/conda/issues/6986" rel="nofollow noreferrer">#6986</a> seems to persist and it is not clear how to deal with it.</p>
  <p>Any ideas on how to approach this? Thank you in advance!</p>
