This page documents common bugs in Fedora 21 and, if available, fixes or workarounds for these problems. If you find your problem in this page, please do not file a bug for it, unless otherwise instructed. Where appropriate, a reference to the current bug(s) in Bugzilla is included.
Release Notes
Read the Fedora 21 release announcement and the Fedora 21 release notes for specific information about changes in Fedora 21 and other general information.
My bug is not listed
Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.
To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.
If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:
- Add it yourself, if you have wiki access. Common bugs instructions provides guidance on how to add an entry to the page correctly, but the most important thing is to make sure that the bug is listed - don't worry if you don't get the format quite right, we can clean it up later.
- Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes
- a summary of the problem
- any known workarounds
- an assessment on the impact to Fedora users
For reference, you can query Bugzilla for bugs tagged CommonBugs:
- CommonBugs? (bugs with CommonBugs keyword, but do not yet have a link to this page)

Installation issues
Network install image offers all package groups
link to this item - Bugzilla: #1134524
This is no longer considered a bug, exactly, but remains documented here for clarity. Initial Fedora 21 plans envisaged Server and Workstation releases each having their own network install images which, by default, would offer only the package groups relevant to that Product. However, it became clear that this design was difficult to implement and not really particularly desired by anyone.
For Fedora 21 Final, there will be a single designated network install image, built from the Server tree, which defaults to the Fedora Server package set but allows installation of all package groups. In practical terms it is little different from the network install image shipped with Fedora 20 and earlier except that it defaults to the Server package group rather than the GNOME desktop, and has Server visual branding. Despite this branding, in practice it is a universal network install image allowing deployment of all Fedora package sets. It can be used for doing network installs of the Workstation product in cases where this is preferable to installing from the live image (e.g. mass deployments).
GNOME issues
GNOME Initial Setup crashes if no keyboard is selected
link to this item - Bugzilla: #1154171
On first use of a Fedora 21 Workstation system (or other Fedora 21 installation with the GNOME desktop), an 'initial setup' process is run (the same as described in the previous issue). One of the early stages asks you to pick a keyboard layout. Depending on your earlier choice of language and location, it is possible that no layout will be pre-selected on the initial list of layout choices. If no layout is selected, and you do not select one but simply click Next, the initial setup tool will crash.
The workaround for this issue is to make sure you select a keyboard layout. If none of the layouts is the one you want, clicking the '...' choice at the bottom of the list will cause the full list of layouts to be provided.

Fedora Server issues
Rolekit fails to deploy a Domain Controller on a VM, returning error 256
link to this item Creation of a Domain Controller role requires the system to have a sufficient amount of entropy available to securely create the keys for the included certificate authority and Kerberos key distribution center. It is very common when deploying on a virtual machine that has just been created that there will not be sufficient entropy available, which will result in the Domain Controller deployment timing out waiting on /dev/random and then failing with error code 256.
On VM hosts that support it (such as KVM on Fedora 20 and 21), it is recommended to create the VM using the virt-RNG device (which the Fedora Server 21 guest will automatically detect). This will allow it to collect entropy from the host machine and should reduce the likelihood of encountering this issue. As a workaround (if you do not have a host capable of providing entropy), you can also run the following command to make the system use the less-secure /dev/urandom entropy device:
# /usr/sbin/rngd -r /dev/urandom
FreeIPA startup fails due to timing issues
link to this item - Bugzilla: #1071356
This bug appears to occur only occasionally. Sometimes, startup of a FreeIPA server - ipa.service - may fail, apparently due to some kind of race / timing issue between it, named.service and dirsrv.target. It does appear to happen only rarely, and when it happens, just starting ipa.service again should succeed.
Other issues
Installation of 'environment groups' fails due to conflicts between fedora-release packages
link to this item - Bugzilla: #1160917
Due to some limitations in how Fedora's package group mechanism works and some changes made to support the introduction of "Products" in Fedora 21, you may often encounter conflicts when trying to install the 'environment groups' seen in yum grouplist after installing Fedora 21. If you install a Fedora Product - Workstation, Cloud, or Server - it is likely that attempting to install any other 'environment group' will fail. If you use a non-Product install - for instance, install from a desktop live image - it is likely that you will be able to successfully install other non-Product environment groups, but not the environment groups associated with each Product.
The most common case in which you're likely to encounter this is trying to add extra desktops to a Workstation or other desktop installation. If you install Workstation and then want to add any other desktop, or install another desktop and then want to add GNOME and decide to try and use the 'Workstation' group, you will likely run into this problem.
Fortunately there is a fairly simple workaround for this problem: just add --exclude fedora-release\* to your command, e.g. yum groupinstall kde-desktop-environment --exclude fedora-release\*.
It may not be possible to resolve this fully for Fedora 21. The bug report contains the detailed explanation of the problem, and solutions for it will likely be discussed there, if you wish to keep up to date.
Rendering problems of Assamese and Bengali language content
link to this item - Bugzilla: #1170135
Rendering issue detected in Lohit Assamese and Bengali last upstream release 2.91.0. Due to this issue conjucts break if it follows by any bengali matra. Unfortunately this got detected during the final phase of Fedora 21 release.
If anyone creating or viewing Assamese or Bengali language content in Fedora they will encounter this issue.
This bug has been fixed in Lohit upstream and available with 2.91.1 release of Assamese and Bengali. One can simple get rid of it by doing $dnf update lohit-bengali-fonts lohit-assamese-fonts -y. This will be available with Zero day update for Fedora 21.
