[SOLVED] Larch Installation from LiveCD

calle · 2009-03-23 21:26:14

Hej!
Today I finally succesfully created a LiveCD from a running Arch System. Because I want to migrate my installation to another partition and of course to check out whether the livecd is functional I tried to install my customized archlinux to hdd. Using larchin for that, I get the following error message after pressing the ok button:

This error couldn't be handled
Traceback (most recent call last):
File "/home/mt/larch/larch5.3/larchin/pkg/opt/larchin/modules/gtk/guimain.py", line 252, in changed_cb

File "/home/mt/larch/larch5.3/larchin/pkg/opt/larchin/modules/stages/finddevices.py", line 79, in getDevices
ValueError: need more than 1 value to unpack

Having found a bug report on http://www.bugs.maryanlinux.com/showreport.php?bugid=3 and having seen it mentioned once here in the forum I don't see a fast solution for this issue. So I'm wondering if there is another way to install the system? What about the installer used for the official installation-images of archlinux? Or maybe some other trick or something I don't see?

thanks in advance

It's a problem scanning the devices on your system (I think). Could you send me the output of these commands (running on the system you are trying to install to): 'cat /proc/partitions', 'fdisk -l' and 'parted -l'. Just run them from a terminal in the larch live system, for example.

If you are trying to install on a fresh disk without partition table, it might be enough just to create a partition with cfdisk or gparted before running larchin. I'm afraid there is no other (easy) way of installing a larch system. However if you just want to transfer a system from one partition to another there are easier ways - use the live CD to prepare the destination partition(s) and copy with cp or rsync - there is probably a wiki page or forum posting somewhere mentioning the few extra steps (grub, fstab, etc.).

See also http://bbs.archlinux.org/viewtopic.php? … 30#p521430.

And if you want to reach me, it is safer to post on the existing larch thread as I don't scan the whole forum regularly.

cat /proc/partitions delivers:

fdisk -l gives:

I hope you can deal with the german pidgin inbetween, sorry.

I'm not trying to install on a fresh disk though. /dev/sda2 is the partition I want to install to.

I will mind posting future larch-questions in the above mentioned post, thanks for the hint.

another question:

I alternatively created another livecd using the archiso scripts, which perfectly worked too. But now I'm looking for a way to modify the archlinux-installer scripts to fit my needs; that is creating config-files fitting for me (e.g. rc.conf with german locales, proper hostname, daemons etc.) and especially for installing the packages i'd like to have installed (like xorg, a desktop environment, whatever programs i like) with predefined configurations (e.g. xorg.conf, desktop-settings, firefox-extensions and so on), so that i can simply run /arch/setup from the livecd as usual but end up with a properly configured system i can start working with right away. Does perhaps anyone know of any further resources i might refer to?

thanks for your help so far

Thanks for the script output. I'll see if I can find anything, though I must say, the output looks completely 'normal' on first glance. Maybe I missed something connected with using other locales (I tend to test only in English - a mistake!).

There have been a few posts about automated installations using the official installer, and I think the new AIF is trying to incorporate something along those lines. Try searching the forums.

are you using larchin as root?
I got this error when trying to run it as simple user.

calle · 2009-03-27 00:16:14

it kinda embarasses me, but yes, that indeed was the problem!

didn't even occur to me, sorry for bothering, gradgrind.

now i almost finished writing a post-installation script that manages my setup, but i think i'm gonna abandon that and use larch now. great stuff! was a great bash lesson though, so no time wasted.

thank you anyway gradgrind and thank you farvardin!
