Synaptic Gtk error

Seems this is the problem:
"sh: cannot create /dev/null: Permission denied"
But I don't know where it comes from.
Are you running uck with sudo?

Fabrizio, do you have any idea?

No, I'm running UCK opening the Applications menu entry.
(But the terminal asks me for sudo password and I give)

i can't find the partimage package but all the other things are working fine to me, synaptic is perfetly installing packages.

anyway the samba package hangs during installation because the postinst operations start the daemon and (within the chroot environment) this should be avoided, but actually i think we can't tell apt not to start daemons after installing packages...

Can these problems be related to the diference between i386 ISO and AMD64 system environment?

I don't think this is caused by an arch mismatch.

I have tried both in my native x86_64 installation and on an i386 installation. The former was 8.04 with all apt-get upgrades applied. The latter was a USB stick prepared by unetbootin with 8.04.1, and I symlinked /home/ubuntu/tmp to a directory of adequate size on my hard disk. In both cases, the symptoms were identical:

Cannot create /dev/null
Synaptic hangs

Also, I cannot execute a console command: An xterm(?) pops up but is then covered by a dialog: "There was an error creating the child process for this terminal". Which sounds like it may be due to the absence of /dev/null.

For some reason, the partition in which my "tmp" directory was located was mounted with options "nodev,nosuid" (presumably some default security policy is operating here). Obviously we need to make sure ~/tmp is on a filesystem with "dev,suid,exec" flags otherwise we don't have a proper chroot environment.

Having remounted with these flags, things indeed work as expected.

splash uck-gui notes were updated with a few info about this

released in 2.0.12

This bug was fixed in the package uck - 2.0.12-0ubuntu1

---------------
uck (2.0.12-0ubuntu1) lucid; urgency=low

  * New upstream release:
    - GUI:
      + splash notes were updated
      + a new configuration screen was added to allow selecting which
        languages will be available on the livecd boot splash (gfxboot).
        This was necessary because the language packs codes do not match
        gfxbook locales.
    - the default gfxboot language can be chosen only between the
      gfxboot available languages (easier selection).
    - default gfxboot language selection was made mandatory
    - Backend:
      + a workaround for the chrooted gnome-terminal was implemented
  * Fixes:
    - LP: #269741
    - LP: #228235
    - LP: #407443

I writing post below to clarify, how to "make sure ~/tmp is on a filesystem with "dev,suid,exec""

When you start uck there's workaround mentioned on welcome screen:
...
Requirements:
1. about 5 GB of free disk space in /home/artem/tmp
   (on local machine and mounted with "dev,suid,exec" options)
...
so it's crucial to remount filesystem where ~/tmp folder resides with "dev,suid,exec" options
(in my case it's a filesystem on a separate partition with mount point /home, maybe you have /home inside root filesystem)

you can do it this way:

sudo mount -o remount,dev,suid,exec /home

or if you have not separate partition for /home:

sudo mount -o remount,dev,suid,exec /

Then try "Run console application" one more time.

Thanks for completing information.
