Alpha Objectives

The objectives of the Alpha release are to:

  1. Publicly release installable media versions of a feature complete test release
  2. Test accepted Changes of Fedora 20
  3. Identify as many F20 Beta blocker bugs as possible
  4. Identify as many F20 Final blocker bugs as possible

Alpha Release Requirements

In order to be released to the general public, a compose must meet all of the following criteria. This is intended to make the decision process as clear and straightforward as possible. Mostly met items are incomplete until they are met. Optional and nice to have items should not be included in this list.

There may be times where a requirement is unmet only in a particular configuration, such as with some keyboard layouts but not others, or if a particular character is used in a username, password or passphrase. In such cases, the release team should use their judgement and refer to precedent to determine whether or not the issue should be considered to block the release. They should consider the number of users likely to be affected by the issue, the severity of the case when the issue is encountered, and the ease or otherwise with which the issue can be avoided by both informed and uninformed users.

The term release-blocking desktops means all the desktop environments in which bugs are currently considered capable of blocking a Fedora release. The current set of release-blocking desktops for the x86 architectures is GNOME and KDE, and for the ARM architectures is Xfce. Note that bugs in desktops that are not part of this set which would infringe these criteria automatically qualify for freeze exception status, according to the freeze exception bug process.

The term release-blocking images means all the images in which bugs are currently considered capable of blocking a Fedora release. The current set of release-blocking images includes the images defined by the three primary Products - Server, Workstation and Cloud - in their product requirement documents and/or technical specifications, and the KDE live image. As of Fedora 24, no 32-bit x86 image can be 'release-blocking', by FESCo policy. The canonical list of release-blocking images for Fedora 31 is on this page.

Process requirements

Alpha blockers CLOSED

All bugs blocking the Alpha tracker must be CLOSED.

FESCo blocker bugs

All bugs deemed by FESCo to block the milestone release must be fixed.

Correct checksums

A correct checksum must be published for each official release image.

No broken packages

There must be no errors in any package on the release-blocking images which cause the package to fail to install.

Initialization requirements

Release-blocking images must boot

All release-blocking images must boot in their supported configurations.

Expected image boot behavior

  • Release-blocking dedicated installer images must boot to the expected boot menu, and then after a reasonable timeout to the installer.
  • Release-blocking live images must boot to the expected boot menu, and then to a desktop or to a login prompt where it is clear how to log in to a desktop.
  • Release-blocking ARM disk images must boot to the initial-setup utility.
  • Release-blocking cloud images must allow login with the user authentication configuration requested during instance creation.

Post-Boot requirements


The installed system must be able to download and install updates with the default console package manager.


Any component which prominently identifies a Fedora release version number, code name or milestone (Alpha, Beta, Final) must do so correctly.

System logging

A system logging infrastructure must be available, enabled by default, and working.


It must be possible to trigger a clean system shutdown using standard console commands.

Alpha Blocker Bugs

A bug is considered a Alpha blocker bug if any of the following criteria are met:

A Fedora Change being incomplete, in and of itself, does not constitute a blocker bug. The Change process is separate from this process. Changes are required to meet certain standards at certain points of the release cycle, but this is part of the Change process and managed, tracked and enforced separately from this process. However, if a proposed feature being incomplete causes any of the above criteria to be met, then the bug is a release blocker.


Contingency Plan

  • If all of the Alpha Release Requirements are not met by 20:00 ETC on Wednesday (1:00 AM UTC Thursday) the week prior to release day, the release will be delayed by one week so that the Alpha Release Requirements can be met.
  • One week will be added to all remaining tasks in the release schedule, including the final release date.
  • This decision will be made at the Go/No-Go Meeting.

Confirming Alpha Requirements

QA has the responsibility of determining whether the criteria for the release has been met (as outlined above) through discussion with Development and Release Engineering. QA's findings will be reviewed and discussed at the Go/No-Go Meeting.
