OK, you anticipated my last before I could send it !!!!!!!!!!!!!!
Would Ubuntu even work if there is not enough disk space?

It could do if Linuxcnc was the last package in the list and there wasn't enough room to install it
That would still leave a little disk space spare.
(It wouldn't even have to be last, so long as the base system was installed and the package that failed and
aborted install, left enough space for the system to initialise)

It's just a speculation based on what little info there is

The change I made was to the actual download page
Installing LinuxCNC

The LinuxCNC team now has custom Live-CDs based on Ubuntu:

10.04 Lucid Lynx/LinuxCNC v2.5 (current),
8.04 Hardy Heron (older)
6.06 Dapper Drake (not supported anymore)

The news column seemed to be OK to me.

@ ArcEye

I’m using the Live CD doing the standard procedure for installing on hard drive.
I just loaded the “ubuntu-10.04-linuxcnc2-i386.iso” image again from the main mirror, to make sure I got the right one. And tried it once again. The Result was the same. So I run your script (thanks btw).

The output was:

“Zugriff auf /usr/realtime-2.6.32-122-rtai nicht möglich: Datei oder Verzeichnis nicht gefunden“
Sorry it’s German (because I’m German ;) ).
It tells that there is no /usr/ realtime-2.6.32-122-rtai File not found.
So I checked the /var/log/installer logs and did the installation again. This time in English, so I can show it here.
In syslog it says at line 1254: Removing linuxcnc ...
And right before that: Removing linux-headers-2.6.32-122-rtai ...
(logs attached)

Well that is truly weird.

Incidently it shows that Linuxcnc 2.4 not 2.5 was sourced from the repositories

More importantly then ubiquity decides to remove the rtai kernel and all the linuxcnc files and replace with the stock Ubuntu 10.04 kernel

May 16 11:48:09 ubuntu ubiquity: Found memtest86+ image: /boot/memtest86+.bin

It also showed various errors relating to ubiquity being unable to resolve host 'ubuntu' near the end, but my syslog has that too.

I will have to run diff on the 2 syslog files to try to see if there is an obvious trigger log event.

This is probably what causes the problem
May 16 11:46:58 ubuntu ubiquity: Selecting previously deselected package linux-image-2.6.32-41-generic-pae.

As soon as that happens, dpkg will purge all the conflicting files and dependencies, ie 2.6.32-122-rtai kernel and all of linuxcnc.
The question is WHY does it revert to the stock kernel?

The only thing that caught my eye so far, is that in the partman log, you chose to format your partition ext4, whereas I always use ext2.
Just wondering if ubiquity thinks the stock kernel is the only one supporting ext4?

Do you fancy having another go, formatting your partition ext2 and re-installing whilst I compare the logs further ?

Nice shot! Ext2 worked.

And suddenly all the little linuxcnc start scrips are where they belong.

Thank You very much!

Hi

Glad you got that sorted - leaves a BIG question as to why ubiquity, which was running on a 2.6.32-122-rtai kernel at the time and quite happily playing with a
ext4 partition, thought it needed the stock kernel.

I will have to look at the modules and try to get hold of the kernel .config file

This probably needs flagging up until resolved

regards
