plugin installation issue

Asked by Willi Wichtig

OpenSuse 15.2
LaserJet M1212nf MFP

Note: The whole setup worked fine until openSuse 15.1, after upgrading to 15.2 the issue occurred only.

1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are installed to successfully compile
HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the proper dependencies installed to
successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Check types:
a. EXTERNALDEP - External Dependencies
b. GENERALDEP - General Dependencies (required both at compile and run time)
c. COMPILEDEP - Compile time Dependencies
d. [All are run-time checks]

I run as normal user hp-plugin, which succeeded:

Done.
 Plug-in installation successful

Then I run hp-setup as root, it finds my printer on the network but then tells me that I need to install a plug-in. It offered to download it again, no option to tell the system that I have installed it already. That's why I choose d to download and install the plugin again. It tells me that the plug-in installation failed.

error: The device you are trying to setup requires a binary plug-in. Some functionalities may not work as expected without plug-ins. Please run 'hp-plugin' as normal user to install plug-ins. Visit http://hplipopensource.com for more infomation.

In essence I am stuck in a loop here, hp-setup tells me plugin is missing, plug-in installation tells me all fine. hplib.state file shows plug-in as installed (=1 correct?). So where does hp-setup try to look if the plug-in is installed or not?

Any idea what to do next?

Thanks!

Hi ,

Can you please try to install plugin using "sh" command instead of "Hp-plugin" :

$sh hplip-3.19.12-plugin.run

Please let me know if you face any issue.

And also , Suse 15.2 will be supported in our next release 3.20.9

Hi,

where do find this hplip-3.19.12-plugin.run? I am not able to find it on my PC. So I downloaded that file from your archive (exactly the version I use). When I try to run it I get

~/Downloads> ./hplip-3.19.12-plugin.run
Verifying archive integrity... All good.
Uncompressing HPLIP 3.19.12 Plugin Self Extracting Archive..............................................................
Error importing HPLIP modules. Is HPLIP installed?

HPLIP is installed, it is installed from the openSuse repository, so assuming that I have a correct installation.

Other question, when do you expect 3.20.9 to be released?

Thanks!

Hi ,

Plugin is showing this error because run file is not installed properly.

We will release 3.20.9 on september end only. You can install that file also.

okay I got now 3.20.9 from your download page. I have run the run file and it installs the plug-in without reporting an error. Nevertheless once the GUI printer install comes up, it detects the printer, but then I get this error and I am not able to continue

Anyone an idea on this?

Found a solution which works for me. I modified

/usr/share/hplip/fax/marvellfax.py:

            if pluginObj.getStatus() != pluginhandler.PLUGIN_INSTALLED:
                log.error("Loading %s failed. Try after installing plugin libraries\n" %lib_name);
                log.info("Run \"hp-plugin\" to installa plugin libraries if you are not automatically prompted\n")
                job_id =0;
                self.service.SendEvent(device_uri, printer_name, EVENT_FAX_FAILED_MISSING_PLUGIN, os.getenv('USER'), job_id, "Plugin is not installed")
                sys.exit(1)
            else:
                self.libfax_marvell = cdll.LoadLibrary(lib_name)

I removed that if-else statement and had the self.libfax_marvell = cdll.LoadLibrary(lib_name) executed in any case. Then everything went through. I don't need fax features so I cannot say if fax might be working or might not be working.

For further analysis I wanted to write a little test python script running

            from installer import pluginhandler
            pluginObj = pluginhandler.PluginHandle()

            if pluginObj.getStatus() != pluginhandler.PLUGIN_INSTALLED:

to see what these methods return in my case. Unfortnately I am getting "No module named installer". If you can give me a hint where I get this module (I assume I have it somewhere on my harddrive just need the correct import statement). Maybe my debugging will help to improve the installer and thus help other users. Let me know if you want me to do some tests on my end.

Found the modules, so I was able to do some more debugging. The issue lies in pluginhandler.py

    def __getPluginFilesList(self, src_dir):

There you read src, trg and link of models based on the plugin.spec file in /usr/share/hplip. On the latest hplip there are all kind of entries like

/usr/lib/i386-linux-gnu/sane/libsane-hp2000S1.so and
/usr/lib/x86_64-linux-gnu/libjpeg.so.9

The problems are the directories i386-linux-gnu and x86_64-linux-gnu, neither exists on openSuse and thus the installer claims that my plugin installation is corrupted (status -2 in my test script). I have checked on a system running 3.18.6, there the plugin.spec file does NOT have these entries. The first of the two examples above is for example located in /usr/lib/sane. Of course I don't know how other distros have their directory structure, but in openSuse 15.1 and 15.2 the structure is without i386... and x64... in the path.

I would say that either the spec file is buggy, or if you need that structure for other distros then the python script needs to adjust the paths for openSuse somehow.

I hope that helps to fix that bug. From my point of view I would say that this new version won't work for any openSuse user. If there is more I can provide then please let me know.
