[Bug 896817] [NEW] [precise] dpkg can't force installation of multiarch packages with different contents

[Philip Muškovac]

Public bug reported:

Thanks to bug 893826 I'm getting this on my precise setup:

$ sudo dpkg -i /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb 
(Reading database ... 527084 files and directories currently installed.)
Preparing to replace libqt4-declarative 4:4.7.4-1ubuntu3 (using .../libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb) ...
Unpacking replacement libqt4-declarative ...
dpkg: error processing /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb (--install):
 './usr/share/doc/libqt4-declarative/LGPL_EXCEPTION.txt' is different from the same file on the system
Errors were encountered while processing:
 /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb

ok, bug acknowledged, now install the package anyway since I know the
files are in fact the same:

$ sudo dpkg --force-all -i /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb
(Reading database ... 527084 files and directories currently installed.)
Preparing to replace libqt4-declarative 4:4.7.4-1ubuntu3 (using .../libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb) ...

dpkg: error processing /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb (--install):

Errors were encountered while processing:
 /var/cache/apt/archives/libqt4-declarative_4%3a4.7.4-1ubuntu4_amd64.deb

dpkg shouldn't error out there, as now I can't fix my dependencies if I
don't want to remove the respective i386 packages and this doesn't have
any more chances to break the system than using --force-overwrite with 2
not-multiarch packages.
