title: FileZilla cannot open folders for installed package in Ubuntu 18.04
body: <p>I installed LLVM and its components on Ubuntu 18.04. After installation, I wanted to see the installation files to verify them.</p>
  
  <p>The files are located in separate folders in /usr/bin and identical folders in /usr/lib/llvm-8/bin, but when I click on any of the folders, Filezilla responds:</p>
  
  <pre><code>Error:  Directory /usr/lib/llvm-8/bin/clang: no such file or directory
  
  Error:  Failed to retrieve directory listing
  </code></pre>
  
  <p>Whether I navigate to subfolders in /usr/bin or /usr/lib/llvm-8/bin I get the same error message.</p>
  
  <p>I kept the compete installation dialog from Putty for each of the components when I installed it and there were no error messages.</p>
  
  <p>What does this mean?</p>
  
  <p>Thanks.</p>
