Why Linux Mint

Linux Mint community is growing fast and this distributions gains trust and supporters amongst the new users of Linux. The reasons behind this are:

  • Linux Mint is stable
  • it's user friendly
  • has many applications installed
  • it's compatible with Ubuntu

Download Linux Mint

If you want to download it you can get the latest release from:

Linux Mint 18.3 Sylvia

or previous releases from:

Linux Mint Releases

There are several options:

Linux Mint 18.3

Based on Ubuntu and offers 4 options( which depends from design to included packages):

  • Cinnamon - this is my personal favorite. It's beautiful, stylish and has well organized structure. It's easier to work even in comparison to Windows. It's based to Gnome 3 but in some way resembles to Windows. It has many new features like desklets and it's easy to be customized. This one seems to have the biggest community and fan number.

  • Mate - it's based also on Gnome. More resembles to Gnome 2. It's similar to Cinnamon in many ways. In performance point of view both options behave the same.

  • Xfce - It's a lightweight version with simple design. This one is better for older hardware or if you need minimum system load.

  • KDE - this version is for experienced users. You can do many changes in the menu and play with the configurations. Next release Linux Mint 19 will not support KDE edition.


LMDE 2 is based on Debian Stable Packages. This version comes with newer packages in comparison to Linux Mint normal edition for the prices of "incompability" to Ubuntu repositories. This version is cleaner and best suited for experienced programmers. In short it can be described as: everything just works unless it doesn't - and then you will have hard times to make it work.

32-bit vs 64-bit Linux Mint

The short answer is:

If you want to use more than 4 GB Ram go for 64-bit.

Unless you need specifically for 32-bit go for 64-bit. 64-bit has many advantages against 32 like:

  • performance
  • security
  • hardware support and upgrades

Some Linux distributions offers only 64 bit versions nowadays.

How to verify Linux Mint ISO images


Once you downloaded your ISO image then:

Example for version Linux Mint 18.3 "Sylvia" - Cinnamon (64-bit) and using world mirror. You can change to your mirror:

  1. Download file - sha256sum.txt
wget -c
  1. Download file - sha256sum.txt.gpg
  1. Place the 3 files in one folder

  2. Go in this folder and run(it will take some time to run - 10 20 secs):

sha256sum -b *.iso
  1. Compare the results by using program like Meld. The output of this program should be the same as the file: sha256sum.txt

Sample file sha256sum.txt - Linux Mint 18.3 "Sylvia":

output of the command:

$ sha256sum -b *.iso
ecebdf9ac4697b6c2d7feffd1bc5430641bca67c7df122fa2914824dc8844b3a *linuxmint-18.3-cinnamon-64bit.iso

If the output is the same as the file content then your downloaded ISO is OK.


  1. Go to your folder of downloaded ISO file
  2. Open 7zip (or install it - you can run it also as a portable program).
  3. Rightclick on ISO Linux Mint file(in case of installed 7 zip).
  4. Select 'CRC SHA' from the menu.
  5. Then click 'SHA 256'
  6. Compare the generated string to the file sha256sum.txt.

For most users verifying the ISO integrity will be enough

authenticity check


  1. Run command to import signing key:
gpg --keyserver --recv-key "27DE B156 44C6 B3CF 3BD7  D291 300F 846B A25B AE09"
  1. Then in the same folder which contains the ISO and the other 2 files(sha256sum.txt and sha256sum.txt.gpg) run:
gpg --verify sha256sum.txt.gpg sha256sum.txt

Sample output:

$ gpg --verify sha256sum.txt.gpg sha256sum.txt
gpg: Signature made 13.12.2017 (ср) 18,16,15 EET using RSA key ID A25BAE09
gpg: Good signature from "Linux Mint ISO Signing Key <>"
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 27DE B156 44C6 B3CF 3BD7  D291 300F 846B A25B AE09

The important points here are:

  • RSA key ID A25BAE09
  • Good signature from "Linux Mint

That's all for authenticity check of Linux Mint ISO


For Windows in order to perform an authenticity check you may need a third party software. There is nice tutorial describing all steps on this link: How to verify a Linux Mint 18 ISO image on Windows


If you follow the original instructions from Linux mint site: How to verify ISO images

The links for downloading files:

  • sha256sum.txt
  • sha256sum.txt.gpg

may not work. In this case you need to use the mirror of your ISO download.
So in order to get the file directory you need to do:

Copy your mirror link:

remove iso file from it:

Download files:

  • sha256sum.txt
  • sha256sum.txt.gpg
