This looks like a dpkg bug to me.

I have probably the same problem in Lucid:

Setting up samba-common (2:3.4.3-2ubuntu2) ...
dpkg: error processing samba-common (--configure):
 subprocess installed post-installation script returned error exit status 10

[Stefan Fleiter (stefan-fleiter)]

The same error is reported for
samba-common, apt-listchanges, text-common:

Setting up apt-listchanges (2.84) ...
dpkg: error processing apt-listchanges (--configure):
 subprocess installed post-installation script returned error exit status 10
dpkg: error processing tex-common (--configure):
 subprocess installed post-installation script returned error exit status 10

This starts to break some updates, but not all.
How do I debug this problem?

[Stefan Fleiter (stefan-fleiter)]

Moving away the corresponding files in /var/lib/dpkg/info/ repaired the update.

[Stefan Fleiter (stefan-fleiter)]

Addition to last comment:
Moving away the files did not solve the problem because the problem reappeared after removing and installing
theses packages again.

[Stefan Fleiter (stefan-fleiter)]

It seems to be a debconf problem.

The following exists with exit code 10:
LANG=C DEBCONF_DEBUG=developer sudo debconf /var/lib/dpkg/info/grub-pc.postinst configure
LANG=C sudo debconf --frontend=readline /var/lib/dpkg/info/grub-pc.postinst configure

But this one succeeds (notice the additional "sh"):
LANG=C sudo debconf --frontend=readline sh /var/lib/dpkg/info/grub-pc.postinst configure

[Stefan Fleiter (stefan-fleiter)]

I followd the execution of debconf recursively.

The following
/usr/share/debconf/frontend sh -x /usr/bin/ucf --three-way --debconf-ok /var/run/samba/upgrades/smb.conf /etc/samba/smb.conf
failed in
+ db_x_loadtemplatefile /var/lib/dpkg/info/ucf.templates ucf
+ _db_cmd X_LOADTEMPLATEFILE /var/lib/dpkg/info/ucf.templates ucf
+ IFS= printf %s\n X_LOADTEMPLATEFILE /var/lib/dpkg/info/ucf.templates ucf
+ IFS=
 read -r _db_internal_line
+ RET=10 failed to open /var/lib/dpkg/info/ucf.templates: No such file or directory
+ return 10

/var/lib/dpkg/info/ucf.templates was missing

But it does not belong to the files I moved away:
LANG=C ls ~/dpkg_bug/ucf.*
ls: cannot access /home/xxx/dpkg_bug/ucf.*: No such file or directory

A reinstall of ucf fixed this for me.

[Stefan Fleiter (stefan-fleiter)]

bug 505405 seems to be a duplicate of this bug.

[Steve Langasek (vorlon)]

This is not a dpkg bug.

The error returned from the postinst script is a generic debconf error code. Stefan, in your case it was caused by a corrupt dpkg info directory, but there's nothing to say whether or not this is the bug Keith experienced.

Keith, what happens if you try to run ucf by hand like Stefan did?
