Installation Issues

Unable to retrieve FTP repodata

link to this item - Bugzilla: #679709

Due to a bug in the installer, when adding FTP-based package repositories during installation, the installer may report a failure while attempting to access FTP-based repository. No fix is available at this time. To workaround the problem, users are advised to first add an HTTP-based package repository URL (such as Once added, you may edit the newly created package repository, and change the repository URL to the desired FTP-based repository URL.

For additional guidance on installation package repositories, consult the installation guide.

Installation failure when using ksdevice=bootif without bootif=

link to this item - Bugzilla: #704188

When installing Fedora 15 while using the boot argument ksdevice=bootif, the installer will fail abnormally if no BOOTIF= value is provided by the PXE server. Future versions of Fedora will not exhibit this failure. In the meantime, ensure your PXE server is making proper use of the IPAPPEND configuration variable. This variable controls what networking arguments are passed to the kernel, and is typically responsible for providing a BOOTIF= value.

For additional guidance, consult the syslinux IPAPPEND documentation.

Software Issues

General buggy or missing functions in GNOME Shell network applet (hidden networks, WPA2 Enterprise, multiple configurations per interface, mobile broadband etc)

link to this item

GNOME Shell features an integrated NetworkManager configuration interface, provided by an applet in the top panel and a configuration interface in System Settings. However, as of Fedora 15 Beta, these tools have not yet achieved feature parity with the configuration interface from GNOME 2, provided by the old nm-applet. Some features are still missing and there are known bugs with others. Major ones will be listed individually here, but as a general principle, if you encounter problems or missing features trying to configure your network using the GNOME 3 applet and System Settings interface, you can run the standalone nm-connection-editor tool, which makes all the operations not yet implemented in the GNOME 3 interface available. You can launch nm-connection-editor from a console, from the alt-f2 Run dialog, or from the overview (type nm-connection-editor or search for an entry named Network Connections).

GNOME 3's fallback mode uses the old nm-applet, and is not subject to this issue.

Unable to connect to hidden wireless networks

link to this item - Bugzilla: #691139

The GNOME 3 NetworkManager configuration interface in Fedora 15 Beta (the applet by the user menu, and the control center Network entry) contain a bug which causes them to hang if you try to configure a hidden wireless network by typing in its SSID. To work around this bug, you can run the standalone configuration tool nm-connection-editor, either by running it from a console, from the alt-f2 dialog, or by finding it in the Overview (it has the name Network Connections). This tool is able to configure hidden networks correctly. This tool is a useful fallback for any situation where the GNOME 3 configuration interface is problematic or incomplete.

This issue was fixed in the updated control-center- package. To solve the issue, update your Fedora 15 Beta installation as usual. You should no longer encounter this issue after updating to that version or later of Package-x-generic-16.pngcontrol-center.

Unable to connect to Cisco AnyConnect VPN

link to this item - Bugzilla: #696107

The NetworkManager-openconnect package in Fedora 15 Beta has not been updated to work with NetworkManager 0.9, and connecting to a Cisco AnyConnect VPN is only possible using the command-line openconnect tool.

This issue was fixed in the updated NetworkManager-openconnect-0.8.1-9.git20110419.fc15 package. You should no longer encounter this issue after updating to that version of later of Package-x-generic-16.pngNetworkManager-openconnect.

Bluetooth not working after upgrade to F15 Beta

link to this item - Bugzilla: #694519

If the system was upgraded to a version of bluez prior to 4.87-5.fc15, then the bluetoothd service would not have been updated to run under systemd. The permanent fix is to run:

/bin/systemctl enable bluetooth.service

as root

Oh no! Something has gone wrong error screen always appears shortly after login

link to this item - Bugzilla: #698190

Due to a problem with the Fedora update system, for a short time in the Fedora 15 repositories the Package-x-generic-16.pnggnome-shell package was at version while the Package-x-generic-16.pnggnome-menus package was at version 3.0.0-1.fc15, despite the fact that gnome-shell- and gnome-menus 3.0.0-2.fc15 are part of a single update. This combination of packages results in an unavoidable crash in GNOME Shell shortly after it starts up. The first time it crashes, it will re-start itself and a crash notification will appear. The second time it crashes, the GNOME 3 Oh no! Something has gone wrong error screen will appear.

If you updated to packages from the Fedora 15 repository without the Fedora 15 updates-testing repository enabled between 2011-04-15 and 2011-04-21, you may have encountered this issue. The most likely scenario in which this would occur is using the preupgrade tool to upgrade from Fedora 14 to Fedora 15, as preupgrade does not use the updates-testing repository by default.

To resolve this issue, update to gnome-menus-3.0.0-2.fc15 or later. You may need to use an alternative desktop to manage this. If you do not have one available, leave the GNOME session at the error message screen (to ensure a network connection will be available), switch to a console with ctrl-alt-f2, log in as root, and run yum update gnome-menus (or just yum update). Then log in to GNOME again.

Note that the Oh no! Something has gone wrong is a general-purpose error screen and may occur due to other bugs; this is just one case which is known to have affected several users. If you are seeing the screen and you have gnome-menus-3.0.0-2.fc15 or later installed, you are experiencing a different issue.

repomd.xml file reported missing or broken

link to this item - Bugzilla: #703025

When Adding F15 TC1 to a PXE server and using a PXE boot menu to upgrade, the installer will complain about a bad or missing repomd.xml file. This happens when the PXE upgraded machine has no internet connectivity (for example because it is crosscabled to a PXE server). You can hit the "edit" button, and then fix the url to your local http server (usually running on the PXE server). Then you will hit the same issue again, as the installer also searches for the "updates testing" repo. Just point it with url to the same "base" f15 repo on your PXE/http server. Don't forget the unselect the "is mirror URL" tickbox.

Laptop screen dims when switching to battery power or idle mode but never brightens again

link to this item - GNOME Bugzilla: #650405

Due to a bug in the screen brightness control logic in gnome-power-manager, laptop screens will dim as expected when switching from mains to battery power and dim further when the system is idle in battery mode, but will never brighten again when the system is no longer idle, or when you connect back to the mains. Eventually the screen will end up at its lowest possible brightness and be stuck there.

The only workaround is to disable screen dimming via the control center, or to manually reset the brightness to 100% via the keyboard (if you have brightness keys) or the control center every so often.

An updated gnome-power-manager package has been submitted to the updates-testing repository for testing. Users experiencing this problem are encouraged to test this update and report to Bodhi whether it solves the problem. To test the update, run this command:

su -c 'yum --enablerepo=updates-testing update gnome-power-manager'
