Bug Description

Trying to install the Precise Alpha1 release candidate (64-bit) on VirtualBox on a 32-bit Ubuntu guest, ubiquity crashed while installing the system and asked me to file a bug.

TEST CASE
1. Use Precise Desktop AMD64 and start the installation
2. In step 'Prepare' select 'Download Updates while installing' and 'Install third party software'
3. Proceed with the installation

EXPECTED RESULT:
The system installs

ACTUAL RESULT:
The installation fails and the following error is displayed in the logs:
Nov 29 11:53:58 ubuntu ubiquity: dpkg: libc-bin: dependency problems, but removing anyway as you requested:

Seems somehow ubuntu-restricted-addons removes libc-bin and installs libc6-bin:i386. This really shouldn't happen, libc-bin is Multi-Arch: foreign and thus should satisfy :i386 package dependencies, too.

It looks like this is just because libc6 was at different versions on i386 and amd64. This should sort itself out once the versions are in sync; respin images if necessary.

Michael Terry (mterry) wrote :

The basic idea here is that installing libc-bin:i386 is removing libc-bin and thus the system gets in an awkward state (here, it's that libc demands libc-bin, but there is no version of it installed after removing it).

You can reproduce this most simply by just running:
sudo apt-get install libc-bin:i386

Which removes libc-bin and fails to complete because ldconfig is not in PATH.

With the newly posted ISOs (20111129.1) this should work again. Confirmation appreciated. Thanks for the report!
