The driver can be built from source.
NOTE: This is a much easier way to install the drivers.
Download the latest .deb files, such as:
amdvlk_2023.Q2.3_amd64.deb (Ubuntu 20.04 22.04) amdvlk_2023.Q2.3_i386.deb (Ubuntu 20.04 22.04)
sudo dpkg -r amdvlk # If old version is installed on the machine, remove it first. sudo dpkg -i amdvlk_x.x.x_amd64.deb sudo apt-get -f install
sudo dpkg -i "amdvlk_2023.Q2.3_i386.deb" "amdvlk_2023.Q2.3_amd64.deb"
NOTE: Here, both the 32-bit and 64-bit drivers are installed.
The driver can also be installed from the latest driver build available at https://repo.radeon.com:
sudo wget -qO - http://repo.radeon.com/amdvlk/apt/debian/amdvlk.gpg.key | sudo apt-key add - sudo sh -c 'echo deb [arch=amd64,i386] http://repo.radeon.com/amdvlk/apt/debian/ bionic main > /etc/apt/sources.list.d/amdvlk.list' sudo apt-get remove amdvlk # If old version is installed on the machine, remove it first sudo apt update sudo apt-get install amdvlk
