Operating System Update

Every 5 years, a new Long Term Support (LTS) version of Ubuntu is released. Every LTS version gets 5 years of support.

The following table shows, which LTS version is supported for how long.

All CareSuite servers should be updated before the Supported Until date is reached. After the Supported Until date was reached, the server will no longer receive security updates.
