Posted on Distribution Update Ubuntu 18.04.6 LTS . The issue includes only accumulated package updates associated with the elimination of vulnerabilities and problems affecting stability. The versions of the kernel and programs correspond to version 18.04.5.
The main goal of the new issue is to update the installation images for AMD64 and ARM64 architectures. The setting problems associated with the review of the keys during the elimination of the second Boothole vulnerability option in the GRUB2 loader are solved. This resumed the possibility of installing Ubuntu 18.04 on the system with UEFI Secure Boot.
Use the presented assembly makes sense only for new installations, but the release of Ubuntu 20.04.3 LTS is more relevant for new systems. The systems installed earlier can get all those present in Ubuntu 18.04.6 changes through the standard update system system. Support for updates and security corrections for server and desktop editions Ubuntu 18.04 LTS will last until April 2023, after 5 years updates will be formed as part of a separate charge support (ESM, Extended Security Maintenance).
