Installera Debian GNU/Linux 4.0r9

Debian GNU/Linux 4.0 har efterträtts av Debian GNU/Linux 5.0 (Lenny). Vissa av installationsavbildningarna som anges nedan kanske inte längre är tillgängliga, eller fungerar inte längre, och vi rekommenderar att du istället installerar Lenny.

För att installera Debian GNU/Linux 4.0r9 (Etch) kan du hämta du en av följande avbildningar:

Nätverksinstallations-cd (100-150 Mbyte)

Andra avbildningar (netboot, usb-minne, osv.)



Om du bara läser ett dokument innan du installerar, läs vår installationsguide, en snabbgenomgång av installationsprocessen. Andra nyttiga dokument är bland andra:


Här finns en förteckning över kända problem med installationsprogrammet som medföljer Debian GNU/Linux 4.0r9. Om du upplever problem med att installera Debian och inte ser ditt problem beskrivet här ber vi dig sända en installationsrapport där du beskriver ditt problem, eller se wikin för andra kända problem.

Errata för utgåva 4.0r3

Utgåvan rättar de två problemen som beskrivs nedan för 4.0r2.

Errata för utgåva 4.0r2

Utgåvan rättar problemet med konfiguration av seriell konsol med GRUB som beskrivs nedan för 4.0r0.

På grund av en miss använder inte installationsprogrammet den kärna som släpptes i 4.0r2 utan en lite äldre (2.6.18.dfsg.1-13). Moduler som läses in senare i installationen kan vara från en senare version (2.6.18.dfsg.1-16), men eftersom dessa två versioner är ABI-kompatibla borde inte detta medföra några problem.

Av samma grund finns inte det stöd för Nevada SGI O2-maskiner som omnämns i pressmeddelandet faktiskt med i denna utgåva.

Dessa två problem kommer att korrigeras i nästa underutgåva av Etch.

Errata för utgåva 4.0r1

Den nya utgåvan rättar några problem i den ursprungliga 4.0r0-utgåvan. Ytterliagre usb-cd-spelare kommer detekteras och gksu kommer att konfigureras korrekt vid installation med inaktiverat rootkonto (sudo-läge). Det är nu möjligt att skapa ext2-filsystem på amd64.

Spegellistan har uppdateras, dessutom har partitioneringsprogrammet översatts till katalanska och rumänska.

I och med att kärnan uppdateras för den här utgåvan kommer vissa installationsavbildningar som släpptes tillsammans med 4.0r0 (nätverksstart och disketter) inte längre att fungera på grund av att kärnversionen inte stämmer. Cd-baserade installationen påverkas inte.

Errata för utgåva 4.0r0

Disk devices may change on reboot
On systems with multiple disk controllers, the kernel/udev may assign a different device node on reboot of the system than was used during installation due to difference in load order of drivers.
This can lead to failure to boot the system. In most cases this can be corrected by changing the bootloader configuration and /etc/fstab, possibly using the rescue mode of the installer.
Note however that this problem may occur again on subsequent boots. Fixing this issue has priority for the next release of Debian installer.
Resizing of existing ext3 partitions may fail
The installer is currently not able to resize ext3 partitions that have the dir_index and/or resize_inode features enabled. This includes ext3 partitions created with the Etch installer.
You can however manually resize an ext3 partition during installation. Proceed until the partitioning step, use the <Go Back> button to exit to the main menu, start a shell, and resize the file system and partition using the commands available in the shell (fsck.ext3, resize2fs and e.g. fdisk or parted). If you start partman again after completing the resize operation, it should show the new size of the partition.
Error using loop-aes encryption during hd-media install
If loop-aes encryption is used during an installation using the hd-media images (e.g. from USB stick), this may fail with the following (or similar) error message in the syslog (#434027):
partman-crypto: ioctl: LOOP_SET_STATUS: Invalid argument, requested cipher or key length (256 bits) not supported by kernel.
Cause of this issue is that early in the installation the CD image will have been loop-mounted using the regular loop module, which prevents the loop-aes module from being loaded later.
It is possible to work around this issue by manually unmounting the CD image, unloading the loop module, loading the loop-aes module, and remounting the CD image.
Incomplete installation of Desktop task from full CD
The full CD image is too small to contain all packages needed to install the complete Desktop task. This means that if you only use the CD as a source, only part of the Desktop task will be installed.
You can resolve this either during the installation by choosing to use a network mirror as a source to install packages in addition to the CD (not recommended if you don't have a decent internet connection), or after you have rebooted into the installed system by using apt-cdrom to load additional CDs and then selecting the Desktop task again in aptitude.
Buggy routers may cause network problems
If you experience network problems during the installation, this may be caused by a router somewhere between you and the Debian mirror that doesn't correctly handle window scaling. See #401435 and this kerneltrap article for details.
You can work around this issue by disabling TCP window scaling. Activate a shell and enter the following command:
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
For the installed system you should probably not completely disable TCP window scaling. The following command will set ranges for reading and writing that should work with almost any router:
echo 4096 65536 65536 >/proc/sys/net/ipv4/tcp_rmem
echo 4096 65536 65536 >/proc/sys/net/ipv4/tcp_wmem
General issues after reboot because of UTF-8 default
The installed system is now set to UTF-8 by default. However, not all applications properly support UTF-8 yet, which may result in minor or major problems when using them.
Please check if such problems have been reported yet and, if not, file a bug report against the relevant package (not the installer).
Limited localization of installed system
For the Sarge version of the installer the package localization-config was responsible for part of the localization of the installed system. This package ran as part of base-config, which has been dropped in the release. Adapting localization-config to run before the reboot is on our TODO list, but meanwhile some localization may not be done automatically when installing in languages other than English.
Installation of Sarge not supported
As a result of some structural changes in the installer, installation of Sarge (oldstable) is not supported.
Graphical installer
The graphical installer still has some known issues (see also the Installation Guide):
  • some non-US keymaps are not fully supported (deadkeys and combining characters do not work)
  • touchpads should work, but support may not be optimal; if you experience problems, you should use an external mouse instead
  • limited support for creating encrypted partitions
  • should work on almost all PowerPC systems that have an ATI graphics card, but is unlikely to work on other PowerPC systems
False warning about missing swap when installing the laptop task
When the laptop task is installed, a incorrect warning will be issued by the uswsusp package saying No swap partition found; userspace software suspend will not work. This is only a incorrect warning and software suspend should work correctly. See also bug #427104.
Network driver sky2 known to be broken
The sky2 network driver is known to be broken in the kernel (2.6.18.dfsg.1-11) used in the installer and may cause kernel panics. See for example #404107. #411115 contains a series of patches that may fix the issues.
i386/amd64: serial console setup with GRUB
There are some issues with the way the installer tries to setup GRUB to use a serial console. Full details can be found in the bug report #416310. Briefly, these issues can be resolved by ensuring that the parity and bits options are also passed in the console= definition.
For most people this will mean that instead of booting the installer with console=ttyS0,9600 you should use console=ttyS0,9600n8.
i386: booting the installer may fail on some older systems
Due to a regression in the syslinux bootloader used for most installer images, some older systems may fail to boot the installer. If the boot halts after displaying Loading initrd.gz...., you should try one of the alternative images that use an older version of syslinux. See also bug report #415992.
amd64: formatting an ext2 file system is not possible (fixed in 4.0r1)
Because the ext2 kernel module is not available, it is not possible to create an ext2 file system. This will be fixed with the next update of the installer for Etch.
powerpc: various issues
The PowerPC port has several issues in this release:
  • installation from floppy on OldWorld PowerMac is broken because no device node is created for the swim3 module and as miboot is not included
  • the snd-powermac module is no longer loaded by default as it will lock up some systems; you will need to add it to /etc/modules manually
sparc: CD installs for sparc32 may fail
The esp kernel driver module is broken which means that installation from CD-ROM is broken for most sparc32 systems. We suggest you use the netboot installation method instead.
sparc: installer appears to hang during boot
There are two situations where the installer may appear to hang during boot after displaying Booting Linux.... The first is when there are two graphics controllers present (this is also described in the installation guide). The second is due to a bug in the kernel's ATI framebuffer driver and affects only certain ATI graphics cards.
In both cases the issue can be worked around by adding the parameter video=atyfb:off when booting the installer.
s390: unsupported features
  • support for the DASD DIAG discipline is currently not available
  • support for LCS network interfaces is no longer available
