Today, I downloaded "ubuntu-mate-18.04.4-desktop-amd64.iso" (timestamp: 2020-02-03 18:58) from
http://cdimage.ubuntu.com/ubuntu-mate/releases/18.04/release/
(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.
