# CentOS Support CentOS was discontinued and the operating system will no longer be updated. The Pritunl repositories for CentOS were also discontinued. The [**Oracle Linux Repositories**](/kb/vpn/repositories.md) are fully compatible with CentOS. These can be used to recieve updates for Pritunl. To continue getting system updates the system must be switched to Oracle Linux. Oracle providers a script to [**upgrade CentOS to Oracle Linux**](https://linux.oracle.com/switch/centos/) that will convert an existing CentOS system to Oracle Linux. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
