HPLIP

installer cannot install python-qt4-dbus

Asked by Rob Quin

Hi,
I'm trying to install HPLIP 3.9.4b in order to get my Deskjet F2280 working.
My distro is 64studio. This is a customised version of Debian Etch.

First the install stopped because it couldn't install libcupsys-dev as this package has been replaced by libcupsys2-dev. I followed Rod's instructions in question#69604. This got me a bit further but now the installer can't find the python-qt4-dbus package. A quick search of the Debian repositories shows that this package is not available for Etch and is only available for Lenny. Does anyone know how to work around this?

Of the 9 missing dependencies that the installer warns about, in the log file, python-dbus & dbus are already installed and python-ctypes is available.

Thanks, Rob

Here's the log file:

python-qt4-dbus is only required by versions of hplip since 3.9.2-1 in March as you can see from the Debian Changelog:

http://packages.debian.org/changelogs/pool/main/h/hplip/hplip_3.9.2-3/changelog

Your printer was released in the Spring of last year so you could certainly try an earlier version of hplip. Unfortunately the changelog doesn't say in which version support for your printer was added, and I didn't see that in the hplip tarball either. Maybe Aaron here knows.

Anyway, you can view the dependencies and download various versions of hplip at

http://www.debian.org/distrib/packages#search_packages

Thanks for the suggestion Andrew. I searched around a bit and this is what I came up with.

Installed, I have hplip version 2.7.10-5~etch1
Deskjet F2280 was added to version 2.8.6
            http://hplipopensource.com/hplip-web/release_notes.html
Version available in Lenny is 2.8.6b-4

So I added "deb http://ftp.uk.debian.org/debian/ lenny main contrib non-free" to /etc/apt/sources.list
and put "APT::Default-Release "etch";" in /etc/apt/apt.conf
but apt-get update choked on this so I reverted back to just Etch.

I considered downloading hplip_2.8.6.b-4_i386.deb and doing #dpkg -i
but quite a number of dependencies would need sorting manually as well so I didn't go there.

When the 64Studio people upgrade their distro to Lenny then the problem will be solved.
In the meantime I've bought a longer usb lead and hooked the printer up to another computer that is running Lenny.
The problem isn't solved but as I've side stepped it I will mark it up as solved.

Thankyou again for your ideas and time.

Look up your printer here:

http://hplipopensource.com/hplip-web/supported_devices/index.html

Each one is marked with the minimum HPLIP version that is required.
