Official upstream packages
We recommend using these official upstream repositories with the latest Knot Resolver. Packages available in your distribution's repositories are often outdated (especially in Debian / Ubuntu).
Our latest version undergoes extensive automated testing and is suitable for production. Follow the instructions below to add our upstream package repository to your system. It contains the latest Knot Resolver and latest compatible Knot DNS.
Please note that we occasionally release a major version which may require manual upgrade. Please subscribe to our knot-resolver-announce mailing list to be notified of new releases, including upgrade instructions if necessary.
