title: "CGroup Version"
|
|
description: "More information on why CGroup version marks the installation as unsupported."

## The issue
|
|
|
|
Supervisor depends on a particular version of Docker CGroup to be in use since
|
|
it depends on its features to work properly.
|
|
|
|
Currently Supervisor requires CGroup v1 in a supervised installation.
|
|
|
|
However, the feature set changes and improves over time and therefore, the minimal
|
|
required version may change in the future. When that happens, it will be communicated
|
|
before we publish a version that will require you to upgrade CGroups.
|
|
|
|
## The solution
|
|
|
|
In a supervised installation if you have switched to CGroup v2 you will need to
|
|
revert what you did. Or you can re-run the [supervised installer](https://github.com/home-assistant/supervised-installer)
|
|
to fix it.
|
|
|
|
You should never see this issue on Home Assistant OS as all versions of the OS
|
|
ship with a supported CGroup version.
