Don't put curly brackets around filenames.

Put a space between commands (e.g. md5sum) and arguments (e.g. ~/Downloads/whatever).

Use the correct paths. Paths beginning with a slash use the filesystem root as their root. Relative paths should NOT start with a slash. Use the correct capitalisation.

Learn how to use the command line properly. Try these for starters:

You might also want to consider using a GUI app for computing the MD5 hash. GtkHash is in the Software Centre.

"Will it change?" Yes and no. The .iso file is kind of like a blueprint. It isn't put on the disc itself, so much as used to store all the files that will be put on the disc. But if you were to use the burned disc as a source for a new disc image, it should match up to the original .iso image file.

It's not something for you to worry about though. When it comes to verifying the burned disc, it has its own verifier built in. Use that. Hold down or repeatedly press SHIFT while booting from the installation CD. In the menu that appears, choose "Check disc for defects".

I just right-click the .iso file and choose "Write to Disc...",. That uses Brasero's back end without showing the GUI, so opening Brasero from the menu should work just as well.
