  </code></pre>
  <p>this occurred after a package update where spyder was update from version 4 to 5. This was previously solved by moving /usr/lib/libstdc++.so.6 to the /opt/ directory with version 4, but this solution does not seem to work with 5.</p>
  <p><code>$ Conda list qt</code> returns the following</p>

  <p>Any help would be happily appreciated, thank you!</p>
  <p>Edit: the following forced installs solved the problem.
  <a href="https://anaconda.org/conda-forge/qt-webengine" rel="nofollow noreferrer">https://anaconda.org/conda-forge/qt-webengine</a>
  <a href="https://anaconda.org/conda-forge/" rel="nofollow noreferrer">https://anaconda.org/conda-forge/</a></p>
  <p>conda install directly did not but using the conda-forge variants did.</p>
