    Install ROCm on Ubuntu 20.04.4 and Radeon RX570

Situation

Installing by closely following ROCm Installation Guide because :

it misses to install libnuma-dev and libncurses5
installing dkms breaks ROCm after reboot

Actions

It is very important to install libnuma-dev and libncurses5 before everything:
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install libnuma-dev libncurses5
sudo reboot
Add user to groups render and video:
sudo usermod -a -G render ${USER}
sudo usermod -a -G video ${USER}
Download and install:
wget https://repo.radeon.com/amdgpu-install/21.50.2/ubuntu/focal/amdgpu-install_21.50.2.50002-1_all.deb
sudo apt-get install ./amdgpu-install_21.50.2.50002-1_all.deb
sudo amdgpu-install --usecase=rocm --no-dkms 

Note: it is very important to install without dkms as ubuntu 20.04.4 with kernel 5.13.x works with rocm but it won't if you install dkms (after reboot).

Results

rocminfo calls survives across reboots.
