Clear message


Argitaratze-ohar hauetan, Ubuntu 9.10 eta bere eratorrietan dauden arazoen berri emango dizugu.

Sistemaren Beharrizanak

Ubuntu 9.10 erabiltzeko 256 MBeko memoria behar da gutxienez. Kontutan hartu ezazu zure sistemaren memoriaren zati bat okupatuta egon daitekeela jada, grafiko-txartelak badarabil. Memoria-tamaina minimoa badu zure ordenagailuak, normalean baino luzeago hartuko du instalazio-prozesuak, baina arrakastaz burutuko da eta sistemak egokiro funtzionatuko du instalatu ondoren.

Memoria gutxiago duten sistemek abioko menuan "Ubuntu Instalatu" hautatu beharko dute, mahaigain osoa kargatu ordez, edo instalazio-CD alternatiboa erabili ahalko dute.

Instalazioa

Gomendatutako paketeak modu lehenetsiz instalatuak

Debianen Politika-Gidaliburuak dioen bezala ("ezohiko instalazioetan izan ezik, beste guztietan honekin batera aurkitu beharko liratekeen paketeak zerrendatuko dira 'Gomendatuak' eremuan"), 'Gomendatuak' eremuko paketeak eta 'Menpekotasuna' eremuko paketeak instalatzen ditu orain pakete-kudeatzaileak. Pakete zehatz hauek baztertu nahi badituzu, apt-get --no-install-recommends erabili ezazu; aukera hau betirako ezarri nahi baduzu, APT::Install-Recommends "false"; jarri ezazu /etc/apt/apt.conf fitxategian. Kontutan izan ezazu hala eginez gero, agian programa batzuen ezaugarri batzuk faltako zaizkizula.

(Aldaketa hau Ubuntu 8.10en egin zen.)

Posible da Hibernazioa ezin erabili ahal izatea partizionatze-automatikoan

Posible da instalatzailearen partizionatze-modu lehenetsiaren ondorioz, sistemaren memoria fisikoa baino txikiagoa den swap partizio bat esleitzea. Honek hibernazioaren erabilera eragotziko du (suspend-to-disk), sistemaren irudia ez da-eta swap partizioan kabituko. Zure sisteman hibernazioa erabiltzeko intentziorik baduzu, zure swap partizioa zure sistemaren RAM fisikoa baino handiagoa izan behar da. (354126)

Ez dira beste Sistema Eragile batzuk abio-menuan agertzen Ubuntu 9.10 RC instalatu ondoren

Ubuntu 9.10 RC instalatu ondoren, beste sistema eragileak ez dira ongi erakusten abio-menuan. Hau konpontzeko, erabiltzaileek sudo update-grub exekutatu beharko lukete instalatutako Ubuntu sistemaren agindu-lerroan. (456776)

OEM "argitaratzeko prestatu" ikurra ez da agertzen 'Kubuntu Netbook Edition'-en

Kubuntu Netbook Edition-en OEM instalazio-modua erabiltzean, ez da "argitaratzeko prestatu" ikurrik agertzen mahaigainean. Kubuntu Netbook Edition-en OEM instalazioak burutzen ari diren erabiltzaileek oem-config-prepare exekutatu dezakete agindu-lerroan. (386099)

Eguneratzen

Ubuntu 9.04 darabilten erabiltzaileak prozesu automatiko eta erraz baten bidez eguneratu daitezke Ubuntu 9.10era. Ubuntu-bertsio zaharragoa darabilten erabiltzaileak Ubuntu 9.04ra eguneratu beharko dira lehenik, eta ondore 9.10era. Azalpen zehatzak topatu ditzakezu hemen: http://www.ubuntu.com/getubuntu/upgrading.

Kubuntu darabilten erabiltzaileak zuzenean eguneratu daitezke Kubuntu 8.04tik Kubuntu 9.10era. Honela eguneratzen diren erabiltzaileentzako gomendagarria da Ubuntu 8.10en eta Ubuntu 9.04en argitaratze-oharrak irakurtzea, bertan zehaztutako arazoen berri ere izan dezaten.

Setting wireless regulatory domain via module option no longer supported

Ubuntu 9.10 enables the CRDA wireless regulatory framework for controlling which wireless channels are usable and visible in a particular location. If you previously had to use the module option similar to that below in /etc/modprobe.d/options to allow access to certain channels in your locality then you may find that wireless will not function at all:

  • options cfg80211 ieee80211_regdom=EU

You should remove this kernel module option on upgrade to Ubuntu 9.10 and use the iw reg command instead.

(This change was made in Ubuntu 9.04.)

Upgrade from beta must be triggered manually

A bug in the apt package included in the Ubuntu 9.10 Beta prevents automatic notification of available package updates. Users who have installed or upgraded to Ubuntu 9.10 prior to the Release Candidate should ensure that updates are being made available by running update-manager manually, clicking Check, and installing the presented updates. (449535)

X server crashes when using a wacom tablet

The wacom driver in Ubuntu 9.10 supports automatic configuration, but it conflicts with manual device entries for wacom tablets in /etc/X11/xorg.conf, causing the X server to crash either on startup or shutdown. Please comment out or remove the entries from xorg.conf to get rid of the crashes. (358643)

Kubuntu may keep unneeded guidance power package

The kubuntu upgrade may leave the no longer needed packages "kde-guidance-powermanager" or "guidance-power-manager" installed. Those can be removed.

Ctrl-Alt-Backspace disabled by default in Xorg, configured via XKB

Since Ubuntu 9.04, the Ctrl-Alt-Backspace key combination to force a restart of X is now disabled by default, to eliminate the problem of accidentally triggering the key combination. In addition, the Ctrl-Alt-Backspace option is now configured as an X keymap (XKB) option, replacing the X server "DontZap" option and allowing per-user configuration of this setting.

As a result, enabling or disabling the Ctrl+Alt+Backspace shortcut can now be done easily from the desktop.

Enabling Ctrl-Alt-Backspace for Ubuntu

  • Select "System"->"Preferences"->"Keyboard"

  • Select the "Layouts" tab and click on the "Layout Options" button.
  • Select "Key sequence to kill the X server" and enable "Control + Alt + Backspace".

Enabling Ctrl-Alt-Backspace for Kubuntu

  • Click on the Application launcher and select "System Settings"
  • Click on "Regional & Language".

  • Select "Keyboard Layout".
  • Click on "Enable keyboard layouts" (in the Layout tab).
  • Select the "Advanced" tab. Then select "Key sequence to kill the X server" and enable "Control + Alt + Backspace".

For further information, see: https://wiki.ubuntu.com/X/Config/DontZap

Change in notifications of available updates

Ubuntu 9.10 launches update-manager directly to handle package updates, instead of displaying a notification icon in the GNOME panel. Users are notified of security updates on a daily basis, but for updates that are not security-related, users will only be prompted once a week.

Users who wish to continue receiving update notifications in the previous manner can restore the earlier behavior using the following command:

gconftool -s --type bool /apps/update-notifier/auto_launch false

(This change was made in Ubuntu 9.04.)

MySQL upgrade

In Ubuntu 9.10 MySQL 5.1 has been promoted as the default MySQL server. MySQL 5.0 is still available from the universe repository though. Performing an upgrade via update-manager will correctly handle the transition from MySQL 5.0 to MySQL 5.1. However using a dist-upgrade will not: mysql-server-5.0 will be upgraded instead of being replaced by mysql-server-5.1. If MySQL 5.0 needs to be kept the mysql-server and mysql-client packages should be removed before the upgrade is started.

MySQL Cluster setup

If MySQL has been setup to use the MySQL Cluster engine (NDB engine) upgrade to MySQL 5.1 will not work since the mysql-dfsg-5.1 packages don't support MySQL Cluster. Instead mysql-server and mysql-client should be removed before upgrade and mysql-server-5.0 should be kept. update-manager will automatically take care of this situation. Note that MySQL 5.0 is in universe and thus won't have have the same maintenance coverage as MySQL 5.1 (which is in main).

Other known issues

Switching to ext4 requires manually updating grub

If you choose to upgrade your / or /boot filesystem in place from ext2 or ext3 to ext4 (as documented on the ext4 wiki), then you must also use the grub-install command after upgrading to Ubuntu 9.04 to reinstall your boot loader. If you do not do this, then the version of GRUB installed in your boot sector will not be able to read the kernel from the ext4 filesystem and your system will fail to boot.

Upstart jobs cannot be run in a chroot

Upstart jobs cannot be started in a chroot because upstart acts as a service supervisor, and processes within the chroot are unable to communicate with the upstart running outside of the chroot (430224). This will cause some packages that have been converted to use upstart jobs instead of init scripts to fail to upgrade within a chroot. Users are advised to configure their chroots with /sbin/initctl pointing to /bin/true, with the following commands run within the chroot:

dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl

Avahi will not start if a .local domain is present

The avahi-daemon package, which implements the mDNS "zeroconf" standard, includes a check to avoid running when a conflicting .local DNS domain is present. It is reported that some ISPs advertise such a .local domain on their networks, which will leave Ubuntu 9.10 hosts unable to see names advertised on the local network (327362).

To force the use of mDNS on a network configured this way, users can run the commands:

sudo sed -i -e'/AVAHI_DAEMON_DETECT_LOCAL/s/1/0/' /etc/default/avahi-daemon
sudo service avahi-daemon start

Kubuntu GUI package manager does not warn about installing from unsigned package repositories

The kpackagekit package manager used in Kubuntu 9.10 does not notify users if the packages they are installing come from repositories that are not secured with PGP. Users who have unsigned package repositories in their /etc/apt/sources.list configuration and wish to be informed of any packages installed from these sources should use the apt-get commandline tool as a workaround. (256245)

Amarok will not offer to download additional codecs when running Kubuntu from the live CD

When started from the live session, Amarok will not offer to download additional media codecs when needed, so, for example, it will be unable to play MP3 files. This will work normally after the system is installed to the hard disk. (362538)

Sparc not supported by Ubuntu 9.10

The upstart init system in Ubuntu 9.10 fails to work on the sparc architecture due to an undiagnosed SIGBUS error. Users of Ubuntu on sparc are advised to remain on Ubuntu 9.04 instead of upgrading to 9.10. Assistance in resolving this architecture-specific bug for Ubuntu 10.04 is welcome. (436758)
