This page documents common bugs in Fedora 16 and, if available, fixes or workarounds for these problems. If you find your problem in this page, do not file a bug for it, unless otherwise instructed. Where appropriate, a reference to the current bug(s) in Bugzilla is included.

Fedora 16 pre-release
Fedora 16 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 16 pre-releases. Issues that are fixed will be removed from the page once a fix is available (for instance, an issue that affects the Beta but is fixed in the final release will be removed at the time of that release).

Release Notes

Read the F16 Alpha release announcement and the Fedora 16 release notes for specific information about changes in Fedora 16 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. Please follow the style and guidelines explained in the comments in the page source.
• 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
  1. a summary of the problem
  2. any known workarounds
  3. 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

Installation crashes with DVD or net install image written to USB with livecd-iso-to-disk

link to this item - Bugzilla: #731356

When you write an image to USB with the livecd-iso-to-disk tool, it sets a kernel parameter on the USB stick which attempts to set the language to that used on the host system (the system from which you wrote the USB stick). For some locales, including at least U.S. English, the format of the parameter is not recognized by the Fedora installer, and so if you write the network install or DVD images of Fedora 16 Beta to a USB stick with the livecd-iso-to-disk tool, the installation will crash after the hostname step with the message Error: unsupported locale setting.

To work around this issue, at the initial bootloader screen when booting the USB stick, instead of proceeding directly with installation, hit the Tab key and edit the boot parameters: remove the LANG=en_US.utf8 (or equivalent) parameter entirely. The installer should prompt you for the language to be used, and proceed without crashing.

No workable bootloader action in text mode upgrade

link to this item - Bugzilla: #742207

If you use the text mode of the Fedora installer to perform an upgrade from Fedora 15 to Fedora 16 Beta, there is no usable option at the stage where you are asked what to do with the bootloader. The update option cannot be used due to the switch from grub to grub2, and the skip option will often result in an unbootable system as the kernel(s) referenced in the bootloader configuration will no longer be installed.

The easiest workaround for this issue is to avoid using the installer's text mode, if you can. If you cannot avoid this, you should select Skip bootloader and then manually update the bootloader configuration from the installer shell (available on VT2) or from another OS (such as a live boot) following the upgrade process.

Software issues

X crashes when KDE starts up in a qemu / KVM virtual machine

link to this item - Bugzilla: #731245

If you try to log in to a KDE environment in Fedora 16 Alpha on a virtual machine using the Fedora qemu/kvm stack (such as a machine created via virt-manager, X will crash. If using a login manager, you will see the KDE startup sequence, then the login manager will reappear.

To work around this issue, use the vesa driver: select the Boot (Basic Video) option if booting the live image, or the Install system with basic video driver option if booting the traditional installer. The installed system will use the same driver, and KDE should work.
