For Debian based systems, like Ubuntu, configure the Debian ROCm repository as

##### Install or Update
Next, update the apt-get repository list and install/update the rocm package:
>**Warning**: Before proceeding, make sure to completely
>[uninstall any pre-release ROCm packages](https://github.com/RadeonOpenCompute/ROCm#removing-pre-release-packages):
```shell
sudo apt-get update
sudo apt-get install rocm-rel
sudo apt-get install rocm-dev
sudo apt-get install rocm
```
##### Un-install
To un-install the entire rocm-dev development package execute:
```shell
sudo apt-get autoremove rocm-dev
sudo apt-get autoremove rocm
```
The rocm driver package can be un-installed in a similar way, but the kernel
images will remain on the system because apt-get will never remove old kernels
by default (refer to the file /etc/apt/apt.conf.d/01autoremove-kernels). Kernel
images can be removed manually using dpkg or apt-get directly on the package
names.
##### Installing development packages for cross compilation
It is often useful to develop and test on different systems. In this scenario,
you may prefer to avoid installing the ROCm Kernel to your development system.
In this case, install the development subset of packages:
```shell
sudo apt-get update
sudo apt-get install rocm-dev
```
>**Note:** To execute ROCm enabled apps you will require a system with the full
>ROCm driver stack installed
##### Removing pre-release packages
If you installed any of the ROCm pre-release packages from github, they will
need to be manually un-installed:
```shell
sudo apt-get purge libhsakmt
```
```shell
for package in $(dpkg -l | grep 'kfd\|rocm' | grep linux | grep -v libc | awk '{print $2}');do
echo "=== Removing $package ==="
sudo apt-get purge $package
done
```
If possible, we would recommend starting with a fresh OS install.
#### RPM repository - dnf (yum)
##### Add the AMD apt repository
##### Install or Update
##### Un-install
##### Installing development packages for cross compilation
#### Closed Source Components
The ROCm platform relies on a few closed source components to provide legacy
functionality like HSAIL finalization and debugging/profiling support. These
