Ubuntu has announced the publication of the new version of Ubuntu 20.04.6 LTS, which includes accumulated packet updates aimed at resolving various problems affecting stability. This release version focuses on updating the installation images for the AMD64 architecture. Aiming for it to be used solely for old equipment, users with new systems are advised to opt for Ubuntu 20.04.2 LTS instead.
The kernel and program versions in this updated release corresponds to the versions in 20.04.5. Notable changes include problem resolutions with keys while addressing vulnerabilities in the GRUB2 boot loader, therefore renewing its ability to be installed on systems with UEFI Secure Boot.
Users who have previously installed Ubuntu 20.04 can get all the changes by standard update installation method. The support for LTS editorial offices of Ubuntu 20.04, which includes updates and corrections of security problems will last until April 2025. Further updates will be available for another 5 years through a separate paid support called Extended Security Maintenance (ESM).
