Subject: update-alternatives fails when setting an alternative in manual mode

Date: Tue, 3 Nov 2009 01:32:49 -0600

Package: dpkg
Version: 1.15.3.1

Hi,

On a clean chroot:
# apt-get install mpg123-alsa
...
Setting up libmpg123-0 (1.9.1-2) ...
Setting up mpg123 (1.9.1-2) ...
update-alternatives: using /usr/bin/mpg123.bin to provide /usr/bin/mpg123 (mpg123) in auto mode.
update-alternatives: using /usr/bin/mpg123.bin to provide /usr/bin/mp3-decoder (mp3-decoder) in auto mode.
Setting up mpg123-alsa (1.9.1-2) ...
# update-alternatives --set mpg123 /usr/bin/mpg123-alsa
update-alternatives: using /usr/bin/mpg123-alsa to provide /usr/bin/mpg123 (mpg123) in manual mode.
Can't call method "slave" on an undefined value at /usr/sbin/update-alternatives line 1017.

Cheers,

Hello,

Bug #554136 reported by you has been fixed in the Git repository. You can
see the changelog below, and you can check the diff of the fix at:

commit 4b0a933f75887563d1c1bc278359d091a809e525
Author: Guillem Jover <guillem@debian.org>
Date:   Sun Nov 22 04:23:23 2009 +0100

    u-a: Verify that the alternative used in --set has been registered
    
    Give a proper error message instead of failing with an undefined
    value when calling the slave method. Additionally verify the alternative
    before switching to manual mode, avoiding this way unneeded log messages
    in case of error.
    
    Closes: #554136

The invokation is just wrong, as there's no /usr/bin/mpg123-alsa
alternative. In any case u-a should not fail like this, so I've fixed
this and it will be included in 1.15.5.3, which we'll probably upload
tomorrow.

 .
   [ Raphael Hertzog ]
   * Avoid usage of IO::String in dpkg-scanpackages, rely on Dpkg::IPC
     instead to directly get a pipe file descriptor. Closes: #557013
   * Put "3.0 (quilt)" in the default list of formats tried by dpkg-source
     after "1.0" and before "3.0 (native)".
   * Let dpkg-source fail if several upstream orig.tar files are available
     (using different compression scheme) since we don't know which one
     to use.
   * Add missing "use Dpkg::Gettext" in Dpkg::Changelog::Entry::Debian.
     Closes: #557668
   * When building "3.0 (quilt)" source packages, use QUILT_PATCH_OPTS="-t -F 0
     -N -u -V never -g0" so that quilt is as strict as dpkg-source's internal
     implementation of quilt. Closes: #557664, #558233
   * Before accepting to build a 3.0 (quilt) source packages, ensure that
     debian/patches is a directory (or non-existing) and that
     debian/patches/series is a file (or non-existing). Closes: #557618
   * Dpkg::IPC::fork_and_exec() now includes the changed environment
     variables in the default error message displayed when the sub-process
     fails.

   [ Guillem Jover ]
   * Verify that the alternative used in update-alternatives --set has been
     registered instead of failing with an undefined value in the slave
     method. Closes: #554136
   * Strip leading spaces in the first line of a field's value in
     Dpkg::Control::Hash. Closes: #557547
