Install the Linux Mint Themes and Icons on Arch Linux

mint_themes_install_arch_linux.md

Install required packages

sudo pacman -S git make ruby-sass

Keep everything together

mkdir mint cd mint

Clone the repository

git clone https://github.com/linuxmint/mint-themes.git cd mint-themes

Generate the theme files

make

Copy the files to the system themes folder

sudo cp -r usr/share/themes/* /usr/share/themes

cd ..

Clone Mint-X and Mint-Y icon repositories

git clone https://github.com/linuxmint/mint-y-icons.git git clone https://github.com/linuxmint/mint-x-icons.git

Put icon themes in system icons folder

sudo cp -r mint-x-icons/usr/share/icons/* /usr/share/icons sudo cp -r mint-y-icons/usr/share/icons/* /usr/share/icons

Cleanup

At this point you can delete the mint folder since you won't need it once the files have been copied.

Simple copy paster will suffer with this, I have no idea only guy on comment section are talking about, but worked on non-arch system as well.

+1 for @dprmd

If your having problems with this, try this solution:
Download sassc and python:
sudo pacman -S sassc python
Open the file "generate-themes.py" with a text editor, search for the word "pysassc" and replace it with the word "sassc", and run the command "make" again. Now just copy+paste the folders from "/home/YOURUSERNAME/mint/mint-themes/usr/share/themes/" to "/usr/share/themes/" Command:
sudo cp -r /home/YOURUSERNAME/mint/mint-themes/usr/share/themes/* /usr/share/themes/
Note:
You have to replace "YOURUSERNAME" with your user name. (Just making sure nobody missed that)
And for the icons, you can use the AUR build, since its not broken (mint-y-icons and mint-x-icons)
yay -S mint-y-icons
yay -S mint-x-icons
