MD5 hash value does not match

Today, I downloaded "ubuntu-mate-18.04.4-desktop-amd64.iso" (timestamp: 2020-02-03 18:58) from

(I used Xtreme Download Manager for the purpose.)

I also downloaded "MD5SUMS" (timestamp: 2020-02-12 13:23) from the same URL.

Looks like the MD5 digest of the actually downloaded file does not match with the value given in the MD5SUMS file for this version.

Since I used XDM, I assume there were no issues in file transfer. The downloaded file size (and not the size on the disk) is 1964244992 bytes.

Would appreciate if someone can look into it and try to reproduce the bug. Thanks in advance.

d/l 18.04.4 ... md5sum matches
1d929104587a6036925808eda738d8f0 ubuntu-mate-18.04.4-desktop-amd64.iso

file size:
-rw-rw-r-- 1 user user 1964244992 Feb 17 13:57 ubuntu-mate-18.04.4-desktop-amd64.iso

I can confirm that 1d929104587a6036925808eda738d8f0 MD5 sum matches the ISO.

Please try downloading without using Xtreme Download Manager

Thanks, both of you.

Here is what I did:

  1. Downloads using my existing UbuntuMATE 18.04 LTS (regularly updated):

To keep XDM out as suggested, I downloaded the file using just FireFox. The download took about 4 hours! The file size is right. However, the MD5 Hash Value reported for the FireFox-downloaded file, by Caja, is:


For reference, the earlier, XDM-downloaded file also had the right size, but its MD5 Hash Value reported by Caja was again different!:


  1. Download using Windows:

I also asked a friend to download the file on his Windows machine. He used some download accelerator (I don't know which one). Its MD5 Hash Value was the right one when tested on Windows (using MS File Checksum Integrity Verifier tool, i.e., fvie.exe).

After copying this file to the existing UbuntuMATE, once again Caja reports the right MD5 Hash Value, namely,


  1. My problem is solved for now, though I can't wrap my head around these facts. One thing is certain: In each case, I have checked the MD5 values more than twice, before reporting them here. (I have kept the files for any further investigation, just in case.)

Thanks again, and best,


[1] download via torrent,

[2] check the MD5-sum via a terminal

[3] make the comparison of the two values in Kate (my matches are displayed in the same highlighting colour).

It works well for me.

Thanks. I am done with the issue. (Even the other pieces of software downloaded by XDM suddenly began giving the right digests via all the MD methods!)

But yes, responding to you point-wise,
[1] cool; doesn't matter to me so long the piece comes intact,
[2] of course did it, before reporting here [ :wink: ]
[3] any good editor is good enough for me. (Wrote a lot of code/messages in Notepad, decades ago. That is, the Notepad without the ++! Also remember writing resume using MS Write (not WordPad), and using a line terminal in UAB to check emails, and to checkout "whois". Was never a fan either of VI etc., or of XyWrite.)


Bye for now, you all; I am now signing off. (But have kept the :susp: files intact, just in case I want to see them byte by byte, some day.)

OK, bye for now, really!
