Re: How to verify the ISO image on Windows
Hi there. This is my first time doing this. I Did the integrity check, following all the directions carefully. The problem is I can't get the hash to match. I get the hash 1c 4f 48 60 44 36 85 cd 29 f1 28 f5 6f 69 0f db 32 cc b5 79. I cant find those numbers anywhere on the sha256sum.txt So Im guessing it didn't pass the integrity check. The problem is that I deleted the mirror and tried a different server. I got the exact same hash. I did this 3 times all with the same hash. I am wondering also why the amount of numbers is different on the string of numbers I get in the command window vs what is on the sha256sum.txt. So I am wondering if I am doing something wrong.

Re: How to verify the ISO image on Windows
Hi, scrivdog.
Note:
Windows CertUtil will display the sha256 checksum with space characters to make reading easier, like you had posted:
The sha256sum.txt file, however, holds the checksum without the space characters. i.e. the checksum above would look like this:
Question:
Which Linux Mint installation ISO image file precisely did you download?
There is no Linux Mint Matte 64-bit.
There is, however, Linux Mint 19.2 64-bit.
The corresponding download file would be named linuxmint-19.2-mate-64bit.iso
Its checksum would be:

Hi, welcome to Linux Mint. Your mistake is that you forgot the last part of the command, thescrivdog wrote: ⤴Sun Sep 29, 2019 2:57 pm Hi there. This is my first time doing this.

SHA256
bit:
Code: Select all
CertUtil -hashfile filename.iso SHA256
In the future, when asking for help, please copy & paste the entire command line plus output, plus any other information that might be relevant, that makes it much easier for us to understand what went wrong.
Re: How to verify the ISO image on Windows
Thanks for responding Karl,
I figured out that when you select all and copy the CertUtil line thing and put it in the command box and then replace "file name" with the linux name it cuts off the shasum off the end of it and you have to re-enter it manually. I did that and it gives me the correct numbers. Thank you so much!!
Code: Select all
C:\Users\the people\Documents\iso>CertUtil -hashfile "linuxmint-19.2-mate-64bit(1).iso"
SHA1 hash of file linuxmint-19.2-mate-64bit(1).iso:
1c 4f 48 60 44 36 85 cd 29 f1 28 f5 6f 69 0f db 32 cc b5 79

When I try to authenticate my copy of the 32-bit version of LinuxMint 10.2 (Cinnamon), all I have is this output:
I:\ISO>gpg --keyserver keyserver.ubuntu.com --recv-key 27DEB15644C6B3CF3BD7D291300F846BA25BAE09

gpg: Total number processed: 1

I'm not sure what to do. In the past, I have verified the 10.1 version and the authentication worked successfully.

That output is okay. It means you have already downloaded the key previously. Proceed to step 2.IronKnuckle wrote: ⤴Sat Oct 05, 2019 2:40 pm When I try to authenticate my copy of the 32-bit version of LinuxMint 10.2 (Cinnamon), all I have is this output:

Re: How to verify the ISO image on Windows
Hi. I'm not entirely sure. Try using the correct uppercase capitalization for SHA256, but it should not matter. What version of Windows are you trying this on and what does this say?MarkOsborne wrote: ⤴Fri Oct 11, 2019 11:02 pm Hi, sorry if im re-asking an answered question but when i try to do the integrity test i get this response:

You can also go the 7-Zip route mentioned in the guide for older Windows versions (but I'd still be interested in the answers to my questions above to improve the guide - I wasn't aware that there were CertUtil versions that had trouble with SHA256).

Re: How to verify the ISO image on Windows
Oh wow, I did not see that one coming! The CODE: SELECT ALL is a feature provided by the forum software here, if you click with your mouse on the SELECT ALL then the command code will get selected for easy copy & pasting. The actual command you are meant to copy & paste is the one that comes afterwards in green. I can see how this could be confusing if you're not used to Internet forums.
Re: How to verify the ISO image on Windows
It might be worth noting, for the benefit of those like me who are not very familiar with Windows, that Notepad does not interpret the carriage return character by itself as a new line. It expects both CR and LF. So, the md checksum text file in Notepad will display as a single line. If your iso is not the first one listed, you would need to scroll to the right to find, for example, the 64 bit MATE iso checksum. It took me a while to figure this out.
Thanks for your help!

Re: How to verify the ISO image on Windows
Ah, good point. This was actually finally fixed in Windows 10 but it is true that older versions of Windows would still have trouble with it.peyrol wrote: ⤴Mon Nov 11, 2019 1:23 pm It might be worth noting, for the benefit of those like me who are not very familiar with Windows, that Notepad does not interpret the carriage return character by itself as a new line.

Re: How to verify the ISO image on Windows
Every time i try and do an Authenticity Check i get "gpg: keyserver receive failed: Server indicated a failure" error message, anyone got any ideas on how to fix it?
Re: How to verify the ISO image on Windows
Same here. I assume it is related to the updates not being signed issue from a while ago, and the mirror I downloaded it from hasn't propagated the changes forward. The hash is the same so I'm continuing with installation anyways.
LInux Mint 19.2, Mate edition, 64-bit.

Re: How to verify the ISO image on Windows
Considering that is not the format of the command as I provide it in the guide, did you actually read the guide including the variants to the command provided there in case of connection problems? Also make sure you don't have an application firewall blocking gpg, but that goes without saying.jonpoljones wrote: ⤴Thu Dec 26, 2019 11:23 pm How can I get this done, it's been month I am trying...

Re: How to verify the ISO image on Windows
Hello gm10,
thanks for your response.
As i said, I entered all different commands provided in your post and also on "verify iso tutorial" on the linuxmint website, but non of these works and it is always the same answer. I disabled fire wall and antivirus.
Here is what command prompt says:
Could it be because my computer might be 32bit and I downloaded 64bit?

No, gpg wouldn't even launch if it was 64-bit on a 32-bit install. Here's another alternative I can offer:jonpoljones wrote: ⤴Sat Dec 28, 2019 4:14 pm Here is what command prompt says:
