Known Problems

Ubuntu GNOME Desktop

  • The Accounts menu item in Empathy opens the Ubuntu Online Accounts dialog instead of the Empathy Accounts dialog. As a workaround, run empathy-accounts manually. (BGO:701903) (Fixed)

  • 'CTRL +SHIFT+ALT+R' for screen recording is not working (1265127) (Fixed)

  • Partition resizing is not working in ubiquity (1260473) (Should be Fixed)

  • Choosing check disc for defects displays no readable text (1262841)

  • nvidia-prime won't work when using gdm (1262068)

  • gnome-shell crashed with SIGABRT in g_thread_abort() (1284017)

Boot, installation and post-install

  • Automatic install is broken on drives that contain partitions that either do not have an operating system installed (eg. a user data partition like /home on Linux or D: on Windows), or partitions that have Windows 8 installed. Selecting automatic install (or upgrade) on these systems will result in the whole drive being wiped and all existing data will be lost. There are also problems dealing with systems with multiple drives. This bug is present in released media of 14.04 and 14.04.1. If you have a drive with any pre-existing partitions, or multiple drives, then you should use manual partitioning. Ensure you have backups. (1265192)

  • The desktop image installer cannot unlock existing encrypted (LUKS) volumes. If you need to make use of existing encrypted volumes during partitioning, then use the "Try Ubuntu without installing" boot option to start a live session, open the encrypted volumes (for example, by clicking on their icons in the Unity launcher), enter your password when prompted to unlock them, close them again, and run ubiquity to start the installer. (1066480)

  • When using installer to upgrade or reinstall an existing installation with encrypted swap, the installer may fail to reuse the partition. A warning will be shown, however the installation can be completed. The installed system will not have swap activated and users are advised to recreate swap on their systems. Please see advice about adding and activating swap at: https://help.ubuntu.com/community/SwapFaq (1066342)

  • Installs on very small memory systems may fail to start or exit without completing with no error. It is recommended that swap be created before install for such systems. Please see advice about adding and activating swap at: https://help.ubuntu.com/community/SwapFaq (1172161)

  • In rare circumstances the 'Next' button on the installer 'Install Type' screen is non-functional. This is intermittent and may be resolved by hitting 'Back' and retrying. (1172572)

  • On some systems, after installation, pressing 'Enter' doesn't reboot the system and a hard reset is required (1297851)

  • Live session starts with keyboard set to English US and time zone as UTC even if non-english languages are selected (1297234)

  • Selecting the Myanmar language at the language selection screen in the installer results in a crash (1303516)

  • In OEM mode, language packs are not installed when the end user selects a non-english language and there is no notification (1307983) To install additional languages, open "System Settings -> Language Support", the language support tool will the propose to install missing language packs.

Upgrade

  • Automatic upgrade on drives containing user data partitions, including from other operating systems, and all Windows 8 systems, will result in the whole drive being wiped and all existing data will be lost. This bug is present in released media of 14.04 and 14.04.1. If you have a drive with any pre-existing partitions, or multiple drives, then you should use manual partitioning. Ensure you have backups. (1265192)

  • When the system is upgraded from a previous release via the installer, the user has to re-enter their credentials. If the user's home directory is encrypted and the password differs from the password on the pre-upgrade system, the upgrade succeeds but the user cannot login (1308530)

  • Configuration of the package tex-common fails when 12.04 LTS is upgraded to 14.04 LTS (1304972)

  • Configuration of flightgear fails during upgrade from 12.04 LTS to 14.04 LTS (1308338)

Power Management

  • On some systems, when opening lid, there is a kerneloops with a suspend/resume failure message seen. (1054732)

Desktop

  • SSH and GPG keys configured in the Password and Keys (seahorse) interface (those using the gnome-keyring agents) sometimes fail to be used. (1271591)

  • On rare occasions Unity's Dash doesn't display (nor search for) any applications (1308037)

Migration

Graphics and Display

Networking

  • In order to improve compatibility with other local nameserver packages, NetworkManager now assigns IP address 127.0.1.1 to the local nameserver process that it controls instead of 127.0.0.1. If the system's /etc/resolv.conf is absent or is a static file instead of the symbolic link to ../run/resolvconf/resolv.conf installed by default then this static file will have to be updated by the administrator in order to continue using the NetworkManager-controlled nameserver.

AppArmor

  • The major tools in apparmor-utils AppArmor 2.8.95 have been rewritten to improve maintainability. While this allows us to better support them and add fixes going forward, currently the aa-genprof and aa-logprof CLI tools contain several bugs (1294797, 1296218) that affect their utility. These bugs should be fixed before release or in an SRU. It is recommended that people develop policy manually at this time.

Kernel

  • 1292467 - Some laptops (particularly netbook class) with older graphics can experience poor graphical performance when starting with a high resolution external monitor attached. The reason for this is that some graphics cards (like the Intel 945GSE) cannot support accelerated 3D graphics when the combined width of both screens exceeds a certain threshold (typically 2048 pixels). See the bug for appropriate workarounds.

Feedback

Development of Ubuntu Gnome 14.04, the Trusty Tahr is ongoing and bugs are fixed every day. Before reporting bugs, please ensure your system is up to date and you're installing the latest build. For verifying installation related bugs, updated disk images are available from Daily bootable images for standard PCs/laptops/netbooks.
