# Linux packages Fluent Bit is available for a variety of Linux distributions and embedded Linux systems. The most secure option is to create the repositories according to the instructions for your specific OS. ## Single line install An installation script is provided for use with most Linux targets. This will by default install the most recent version released. ```bash curl https://raw.githubusercontent.com/fluent/fluent-bit/master/install.sh | sh ``` This is a helper and should always be validated prior to use. ## GPG key updates For the 1.9.0 and 1.8.15 releases and later, the GPG key [has been updated](https://packages.fluentbit.io/fluentbit.key). Ensure the new key is added. The GPG Key fingerprint of the new key is: ``` C3C0 A285 34B9 293E AF51 FABD 9F9D DC08 3888 C1CD Fluentbit releases (Releases signing key) ``` The previous key is [still available](https://packages.fluentbit.io/fluentbit-legacy.key) and might be required to install previous versions. The GPG Key fingerprint of the old key is: ``` F209 D876 2A60 CD49 E680 633B 4FF8 368B 6EA0 722A ``` Refer to the [supported platform documentation](https://docs.fluentbit.io/manual/installation/downloads/..#supported-platforms-and-packages) to see which platforms are supported in each release. ## Migration to Fluent Bit For version 1.9 and later, `td-agent-bit` is a deprecated package and is removed after 1.9.9. The correct package name to use now is `fluent-bit`. --- # 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.
