I use the file manager PCManFM in Debian 8 (Stable). When I right-click on a disk image file and select Disk Image Writer, an error message is displayed on the standard error stream saying that the file "does not appear to be a regular file".

I know that the file is OK, since if I write the disk image with the dd command it works as expected. Any clues? Do I need to install any additional packages to make Disk Image Writer work?

Edit: The error message is

file:///home/august/Downloads/ignition.img does not appear to be a regular file
  • Can you replace the quoted error message with the actual text that was output to standard error. Commented Jul 16, 2016 at 16:01

  • What is the output of ls -ld /home/august/Downloads/ignition.img, and file /home/august/Downloads/ignition.img ? Commented Jul 16, 2016 at 21:19

It could be because PCManFM is converting the filename to a URL, and the disk image writer, does not understand URLs. I do not know PCManFM, but on similar tools you can configure how it passes parameters.

  • Do you happen to know which application Disk Image Writer refers to? Commented Jul 17, 2016 at 12:06
  • You will need to look at the configuration, to find out. Is the configuration UN-altered by you? If so you may have found a bug. Commented Jul 17, 2016 at 12:54
