Debian 11 Bullseye's official Long Term Support (LTS) ends on August 31, 2026, marking the cessation of security updates from September onwards. Users still on Bullseye have options, including commercial Extended Long-Term Support from Freexian, which runs until June 30, 2031, but only covers specific packages and architectures. The recommended upgrade path is to Debian 12 Bookworm or Debian 13 Trixie, both of which are currently under LTS, with Bookworm supported until June 2028 and Trixie until June 2030. Users are advised to review their systems for unsupported packages and plan their migrations before the deadline, as continuing with Bullseye after September will leave them without official security support
