Introducing how to install the arc-theme theme on Ubuntu PC/server and configure/apply the theme. Using Ubuntu version 18.04 as an example.
Copy and paste the following commands.
# To build the theme the follwing packages are required
sudo apt-get update
sudo apt-get install -y autoconf
sudo apt-get install -y automake
sudo apt-get install -y gtk2-engines-murrine
sudo apt-get install -y libgtk-3-dev
sudo apt-get install -y gnome-tweak-tool
sudo apt-get update
# Clone the git repository with
git clone https://github.com/horst3180/arc-theme --depth 1 && cd arc-theme
# 2. Build and install the theme
./autogen.sh --prefix=/usr
sudo make install
gnome-tweaks
Start settings with gnome-tweaks, and you can select the Arc theme in appearance > themes.
In ubuntu16.04, this was gnome-tweak-tool. The only difference is around here.
