title: Can't change permissions on /snap/inkscape/4019 directory. chmod: changing permissions of '4019/': Read only Filesystem
body: <p>I am trying to edit the <code>scour.inkscape.py</code> file in the <code>/snap/inkscape/4019/share/inkscape/extensions</code> directory. The permissions for this file is set to <code>-rwxr-xr-x</code>. Problem is linux won't let me make any changes in the <code>/snap/inkscape/4019</code> directory. I can make any changes outside this directory though. This is what the inkscape directory looks like: </p>
  
  <pre><code>total 0
  drwxr-xr-x 10 root root 276 Mar 11 18:05 4019
  lrwxrwxrwx  1 root root   4 Jul 23 01:06 current -&gt; 4019
  </code></pre>
  
  <p>When I try to change permissions on the 4019 dir with <code>sudo chmod 777 4019</code>, chmod throws a error: </p>
  
  <blockquote>
    <p>chmod: changing permissions of '4019/': Read-only file system.</p>
  </blockquote>
  
  <p>Pretty much all posts that I read about the issue told to remount the filesystem or reboot, but the 4019 directory is not a filesystem, it is a directory and rebooting didn't work. I'm running Ubuntu Mate 16.04. </p>
