Disk Usage Analyzer Permisions

I have used almost all of my 64 GBs of storage and I’m not sure what’s causing this (I’m only using 1.5 GB of this from Steam games). I went to the Disk Usage Analizer and it gave me this message at the top of the screen:
Could not scan some of the folders contained in “/”
Error openind directory ‘etc/cups/ssl’: Permision denied

I think that the ‘etc/cups/ssl’ is the first folder/file it finds that it can’t see as it does not show many folders under “/”. (etc, srv, and mnt).

What it shows:

Something that would help us a lot to understand the problem would be this:

  1. Open the application called ‘Terminal’
  2. In this application run the command:


  1. The above command will create a file with the information of your system (example: eos-diagnostic-160614_111731_UTC + 0100.txt); Send us this file so we can analyze and see a possible solution

Take a look at the “Installed” tab in App Center, and see if there are any apps installed that you do not use. Having done that, try running flatpak uninstall --unused to remove any unused application runtimes.

I filed an issue against the disk usage analyzer application some time ago:

You can work around this by opening the menu, choosing “Scan a directory”, and scanning the /sysroot directory.
