Help installing missing dependencies for HPLIP

p's-Qs · 11-24-2019, 12:50 PM

Hi there!

While trying to set up my printer and installing HPLIP, I got this message:

MISSING DEPENDENCIES
--------------------
Following dependencies are not installed. HPLIP will not work if all REQUIRED dependencies are not installed and some of the HPLIP features will not work if OPTIONAL dependencies are not installed.
Package-Name Component Required/Optional
libcrypto network REQUIRED
libnetsnmp-devel network REQUIRED
sane-devel scan REQUIRED
pil scan OPTIONAL
pyqt4-dbus gui_qt4 REQUIRED
python-devel base REQUIRED
cups-devel base REQUIRED
python-dbus fax REQUIRED
reportlab fax OPTIONAL
pyqt4 gui_qt4 REQUIRED
libusb base REQUIRED
libtool base REQUIRED
cups-image base REQUIRED
python-notify gui_qt4 OPTIONAL
xsane scan OPTIONAL
libjpeg base REQUIRED
dbus fax REQUIRED
Do you want to install these missing dependencies (y=yes*, n=no, q=quit) ?

and then

INSTALL MISSING REQUIRED DEPENDENCIES
-------------------------------------
note: Installation of dependencies requires an active internet connection.
warning: Missing REQUIRED dependency: python-devel (Python devel - Python development files)
warning: This installer cannot install 'python-devel' for your distro/OS and/or version.
error: Installation cannot continue without this dependency. Please manually install this dependency and re-run this installer.

Now, I've since managed to install a few of these on my own. The ones I haven't been able to figure out how to install are:

sane-devel
pil
pyqt4-dbus
cups-devel
reportlab
pyqt4
libusb
libtool
cups-image
libjpeg
dbus

Out of these, I get the following for libtool and dbus

Reading package lists... Done

libtool is already the newest version (2.4.6-0.1).
0 upgraded, 0 newly installed, 0 to remove and 24 not upgraded.

dbus is already the newest version (1.10.6-1ubuntu3.4).

and this message for the rest of them

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package [package name]

I'd really appreciate any input as to how to install the these/ get my printer running!

printer is HP DeskJet 3762
elementary OS 0.4.1 Loki for a distro

Thanks in advance!

How have you been trying to install hplip? I definitely wouldn't recommend downloading it from the HP site. That's how you install stuff in Windows, but in Linux it's nearly always a bad idea. Remember, the people on that site have no idea what kind of Linux system you have. The fact that they mention -devel packages suggests that you have got a Red Hat version, whereas your OS belongs to the Debian family.

In fact most distros these days have hplip as a prebuilt package which you install using your package manager. Any required dependencies will then come over automatically.

Open a terminal and type

Code:

sudo apt install hplip

then follow instructions.

Thank you for your reply!

I did download from the HP site.

That's good to know, thank you!

I read about that but also read that downloading from the site could be helpful if there were any problems. Since the printer didn't show up upon being plugged in, I figured I'd give that a go.

I've now followed your instructions:

Building dependency tree
Reading state information... Done
hplip is already the newest version (3.16.3+repack0-1).
hplip set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 24 not upgraded.

I'm guessing this means it's already installed, like you said? The printer still doesn't show up when plugged in though.

I ran the

Code:

hp-check

command as suggested on the HP troubleshooting site and got a lengthy message which I can share if it's helpful but the main points seem to be:

warning: "elementary" distro is not found in AUTH_TYPES

warning: unknown-0.4.1 version is not supported. Using unknown-0 versions dependencies to verify and install...

warning: HPLIP-Installation: Auto installation is not supported for unknown distro 0.4.1 version

warning: Failed to read /etc/cups/ppd/HP_DeskJet_3700_series.ppd ppd file

warning: Printer is not HPLIP installed. Printers must use the hp: or hpfax: CUPS backend for HP-Devices.

error: Unsupported model: DeskJet_3700_series

and

| SUMMARY |

-----------

Missing Required Dependencies
-----------------------------
None

Missing Optional Dependencies
-----------------------------
None

Total Errors: 12
Total Warnings: 1

So does this mean the printer, distro and HPLIP are not compatible/ supported by one another? Is there anything I can do about this?

Thanks again!

Most of those warnings are spurious. They just mean that HP have never heard of ElementaryOS. So what! The one about /etc/cups/ppd/HP_DeskJet_3700_series.ppd is more interesting. Do you actually have this file? If not, hopefully you will have a copy somewhere else, probably somewhere in /usr/share/ppd or /usr/share/cups.

Open a terminal and type "locate HP_DeskJet_3700_series.ppd". If you can find it, copy it over as root. It might be all you need.

Alternatively, have you tried installing the printer using the cups web interface? If not, we can talk you through that.

btw I have found HP Deskjet 3740 on openprinting.org so 3700 should work too.

p's-Qs,

I find the HP “Walkthrough” very reliable and easy to follow.

All the missing dependencies will be installed as the installation proceeds.

https://developers.hp.com/hp-linux-i.../install/index

Download hplip-3.19.11.run (for Ubuntu) to either your Desktop or Downloads folder.

Then in Terminal:

Code:

cd Desktop

(OR cd Downloads)

(Press Enter).

Then:

Code:

sh hplip-3.19.11.run

(press Enter)

Then follow the interactive guide.

How do I know if I have it? After typing in what you suggested nothing happens. Do I need to do anything else?

No, I haven't. It'd be really helpful if you could walk me through that! Thank you!

Ah, good to know!

beachboy2, thanks for your reply! That's what I tried before starting this thread. I did find the HP walkthrough helpful. That said, the missing dependencies weren't installed automatically, hence my initial question in my first post.

The command line only gives you output when there's something to print. If locate doesn't print anything, it means it can't find the file, so it really hasn't been installed. But since you have downloaded a driver from HP, it's worth unpacking that and looking for the ppd file you need.

Installing a printer via cups is normally easy. Open your browser and go to localhost:631. You'll need a password to get into the admin section; probably your own password will do as for sudo, but in some distros, you need the root password. Try asking cups to autodetect the printer. If that doesn't work, you can opt to install it by hand.

I hope you're still here. You solved in one post (the one saying (basically) "Don't download anything from HP for Linux"), the problem I've been working on for a day and a half.

I'm a Linux newbie and you've helped me make some progress!

Bless you,

With hplip installed you can use the command line to configure an HP printer with

Code:

hp-setup

The setup tool will walk you through the steps.

One thing you must do manually for a network connected (wifi or otherwise) printer is configure the printer for a static IP address so it does not get randomly reassigned by DHCP as sometimes happens.

Once you have that the setup tool walks you through the config and it just works for me.

There also is a gui tool that can be installed to aid in setup and printer management. It can be installed with

Code:

sudo apt install hplip-gui

then you will have a gui tool to do the management that takes several commands from the command line.

As a new user it is also helpful to know that once an HP printer is configured the print side will just work and hplip will be updated along with other software in the future. The drawback to keep in mind is that the plugin for the scanner on an MFP printer is proprietary and must match the hplip version. When hplip is updated it does not automatically update the scanner plugin.
The fix, if the scanner on your MFP HP printer does not work, is to run

Code:

hp-plugin

to update the plugin to match the hplip version and scanning will be able to resume once that completes.
