Understanding the Delay: Why Ubuntu 26.04 Upgrades from 24.04 Are Pushed to September

If you’re curious about why direct upgrades from Ubuntu 24.04 to 26.04 are delayed, there’s an explanation. Canonical has announced that upgrades will be postponed for a few weeks to allow important backports to be implemented. Specifically, these updates aim to fix issues stemming from a recent release of rust-coreutils.

While users on Ubuntu 25.10 do not face this delay, as that version’s upgrades were already made available in April, the situation with 24.04 requires more caution. Unlike the fixed ISOs released on a set schedule, upgrades are more complex, involving the migration of numerous interlinked packages and dependencies—making them more prone to issues, especially regarding stability in LTS versions.

This delayed upgrade period is particularly important, as it allows for additional testing to identify and resolve any edge case bugs before making the transition official post the first point release. For those who can’t wait, it is technically possible to perform an upgrade via the command line using a development flag, but this comes with risks involving potential bugs.

For users who do decide to wait, the migration to 26.04 should be possible in early September. Meanwhile, Ubuntu 24.04 will be receiving support through regular updates until 2029, extending to 2034 with the Ubuntu Pro service enabled.
