Verify your ISO ?
 
How do I "Browse a mirror" so that I can download the two files needed to verify the Mint 18.1 cinnamon 64 bit iso file that I have downloaded?

This page: https://linuxmint.com/verify.php

says download the files but not how to go about it. Thanks.

Click the link for sha256sum.txt which should display a bunch of text in the web browser. On Chrome the download button looks like an elevator Down button. Clicking that will either put the file in your Downloads folder or ask you where to put it. Once you have the file you can copy it with your file browser.

You can also goto the command-line and type:

Code:

md5sum name-of-iso-file-here
or

Code:

shasum name-of-iso-file-here
The md5sum is less secure than shasum.

same place you downloaded it from?

Or open your pointy-clicky to

http://mirrors.evowise.com/linuxmint/stable/18.1
and get what you want.

Mint doesn't publish md5sum hash values because it doesn't rely on them.

Code:

sha256sum /path/to/mint.iso
or cd into the directory where the mint.iso is downloaded, likely Downloads, so in terminal, issue
Code:

cd Downloads
sha256sum -b mint.iso

Should yield one of these (appropriate to whatever you downloaded)
Code:

Prove it yourself:
Code:

wget http://mirrors.evowise.com/linuxmint/stable/18.1/sha256sum.txt && cat sha256sum.txt
If it's not one of the above^^, rerun
Code:

sha256sum -b mint.iso
again and if it fails to produce one of the above sha256 hash sums,
delete the mint.iso and try a fresh download.

Code:

sha256sum -b mint.iso
Once you have verified the sha256 hash, it is verified.
the sha256sum.txt itself could be checked using
Code:

sha256sum sha256sum.txt
I show:
Code:

and the sha256sum.txt.gpg is
