Thread: i386 postgres on i686 debian with multiarch

Hi,

I'm trying to set up a replica for a postgres 9.3 instance running on an older i386 debian install, replicating to a 64 bit install. 

Having enabled multi-arch** support on the 64 bit debian by running:

dpkg --add-architecture i386 

and trying to install:

apt-get install postgresql-9.3:i386

gives:

"Depends: ssl-cert:i386 but it is not installable"

Any way of getting postgres i386 to depend on an arch independet ssl-cert ? The ssl cert's should be the same on both platforms I think?

Has anyone gotten this to work?

Thank you in advance!

Damian

Firstly verify the contents of

/var/lib/dpkg/arch

This file usually contains

amd64
i386

when multiarch support is enabled.


You must run

apt-get update

to re-build your package lists AFTER enabling multiarch.

However, I only use 64 bit PostgreSql.

HTH.

Hi Rob,

Thank you for your response:

cat /var/lib/dpkg/arch

gives:

amd64
i386

I did update after adding i386- I don't think it would have found
postgresql-9.3:i386 otherwise.

Further reading indicates that packages can explicitly support
multi-arch and permit (some) dependent packages to be from either
architecture.  I would wager ssl-certs is one of these.  I can't seem to
find the Debian packaging bits - they don't seem to be part of the
source tarball.  If someone could point me at these I'd be happy to have
a stab at changing it to support multi-arch.

Thanks!
Damian
