Package: libjs-prototype
Version: 1.7.1-3
Severity: important
Dear Maintainer,
* What led up to the situation?
I asked aptitude to install darktable:amd64 on a newly upgraded
jessie multiarch system. Dpkg reports as follows:
: nr@homedog 10074 ; dpkg --print-architecture
i386
: nr@homedog 10075 ; dpkg --print-foreign-architectures
amd64
* What exactly did you do (or not do) that was effective (or
ineffective)?
* What was the outcome of this action?
Marking the package with the plus sign resulted in an error
messages that two dependencies of darktable:amd64 are not
satisfied. They are
libjs-prototype:amd64
libjs-scriptaculous:amd64
These packages, without the :amd64 suffix, are installed on
my system, and dpkg -s reports
Architecture: all
I suspect that something may be wrong with the dependencies.
* What outcome did you expect instead?
I expected the darktable:amd64 package to be installed.
I reported this problem against darktable as bug 785163, but the
darktable maintainers suggest that the problem actually lies in the
dependencies. In searching documentation online, I found the
following statement about Architecture: all packages
Pre-multiarch, architecture-dependent packages may depend on
Architecture: all packages and assume that the transitive dependencies
will be resolved using packages of the same architecture or other
packages that are Architecture: all. To avoid breaking this
assumption, Architecture: all packages will, at least initially, be
treated as equivalent to packages of the native architecture for all
dependency resolution.1 This means that for an Architecture: all
package to satisfy the dependencies of a foreign-architecture package,
it must be marked Multi-Arch: foreign or Multi-Arch: allowed.
According to the documentation I can find,
Multi-Arch: foreign
might be suitable for your package.
I have confirmed that if this line is added to your debian/control
file, the package installs, and (when other dependencies are similarly
updated), aptitude installs darktable:amd64 without complaint.
