Oneric's ia32-libs has unresolved dependencies, breaks subversion

[Lucas Magasweran]

On my clean installation of Ubuntu 11.10 64-bit I installed subversion using apt-get. I tested it and it works. Afterwards I install ia32-libs using apt-get (for a binary toolchain I use). Then I notice subversion no longer runs (file not found). If I run aptitude on another machine where I've clean-installed Oneric I see the following when attempting to install ia32-libs:

Leave the following dependencies unresolved:
100) ia32-libs recommends ia32-libs-multiarch
101) libdbus-1-3 recommends dbus
102) libgl1-mesa-glx recommends libgl1-mesa-dri (>= 7.2)
103) libqt4-sql recommends libqt4-sql-mysql | libqt4-sql-odbc | libqt4-sql-psql | libqt4-sql-sqlite
104) sysvinit-utils recommends upstart (>= 0.6.3-4)

These are unresolved recommends, not broken dependencies. They are expected.

And I don't know what broke subversion for you, but it wasn't ia32-libs. You didn't give the text of the error message, so it's impossible for us to diagnose.

Let me try and recreate the problem and capture all the error messages.

[Lucas Magasweran (lucasrangit)]

The error when executing Subversion is:

user@host:~$ svn --version
bash: /usr/bin/svn: No such file or directory

[Lucas Magasweran (lucasrangit)]

Here's the installation log of the ia32-libs package.

[Lucas Magasweran (lucasrangit)]

Before installing the ia32-libs package I can run Subversion:

user@host:~$ svn --version
svn, version 1.6.12 (r955767)

user@host:~$ sudo apt-get install ia32-libs | tee ia32-libs.txt
(see log in previous comment)

[Lucas Magasweran (lucasrangit)]

Oh! I see my confusion now. Sorry, but it appears ia32-libs uninstalled subversion (that would explain why I cannot execute it). If I try to re-install it I get the following error message:

user@host:~$ sudo apt-get install subversion | tee subversion.txt

[Lucas Magasweran (lucasrangit)]

I've just performed the exact same steps on a clean installation of 11.04 64-bit and have a working installation of Subversion after the installation of the ia32-libs package. Please let me know if there's any more information I can provide.

[Steve Langasek (vorlon)]

For some reason, the ia32-libs install is pulling libxml2 in on your system. Please show the output of this command:

sudo apt-get install ia32-libs ia32-libs-multiarch:i386 libxml2

[Lucas Magasweran (lucasrangit)]

Hi Steve, thanks for follow up. Here's the output:

user@host:~$ sudo apt-get install ia32-libs ia32-libs-multiarch:i386 libxml2
[sudo] password for svn:
Reading package lists... Done
Building dependency tree
Reading state information... Done
ia32-libs is already the newest version.
ia32-libs-multiarch:i386 is already the newest version.
ia32-libs-multiarch:i386 set to manually installed.
The following packages were automatically installed and are no longer required:
  libapr1 libaprutil1
Use 'apt-get autoremove' to remove them.
The following packages will be REMOVED:
  libxml2:i386 shared-mime-info:i386
The following NEW packages will be installed:
  libxml2
0 upgraded, 1 newly installed, 2 to remove and 0 not upgraded.

Do you want to continue [Y/n]?

[Steve Langasek (vorlon)]

ok, so the culprit is shared-mime-info; for some reason apt calculated that it would be better to install the i386 version of this package instead of the amd64 one, despite the package being Multi-Arch: foreign (meaning any architecture will suffice, but the native architecture is preferred). And shared-mime-info has to have a matching version of libxml2, which has not been converted yet for multiarch, resulting in the amd64 version being kicked out.

If you had already had the amd64 shared-mime-info installed before installing ia32-libs, this probably would not have occurred.

Assigning this bug to apt, which should be more aggressive about preferring the amd64 package versions.

[Lucas Magasweran (lucasrangit)]

That works! So the workaround I just tested from a clean-install is:

$ sudo apt-get install shared-mime-info
$ sudo apt-get install ia32-libs
$ sudo apt-get install subversion
$ $ svn --version

Thanks!
