Cannot install HP printer: plugin installation not successful

  • 772

I am trying to set up my HP LaserJet P1102 on Ubuntu 19.04.

I know the theoretical procedure to install the printer, but this procedure does not work for me, following the "correct" procedure to install the printer (the software + the plugin) fails as follows.

I have downloaded and installed hplip 3.19.5 from here.

At first the installation seems to succeed. It asks for plugin to be installed, then it says "Plugin installation successful". But after I click OK on this message, it returns to the window in which I should choose which printer to install, and another message pops up:

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.

error: hp-setup failed. Please run hp-setup manually.

    Same here. I solved this way:

    please run:

    hp-setup -g &> ~/hp-setup.log

    after your error read the log:

    cat ~/hp-setup.log

    you will find some lines like:

    hp-setup[19265]: debug: Either /usr/lib/i386-linux-gnu/sane/libsane-hp2000S1.so file is not present or symbolic link is missing

    if you run:

    locate libsane-hp2000S1

    you will get the right place like:

    • /usr/lib/sane/libsane-hpgt2500-x86_64.so.1.0.22
    • /usr/lib/sane/libsane-hpgt2500-x86_64.so.1.0.27
    • /usr/lib/sane/libsane-hpgt2500.so
    • /usr/lib/sane/libsane-hpgt2500.so.1
    • /usr/lib/x86_64-linux-gnu/sane/libsane-hpgt2500.so
    • /usr/lib/x86_64-linux-gnu/sane/libsane-hpgt2500.so.1
    • /usr/lib64/sane/libsane-hpgt2500-x86_64.so.1.0.22
    • /usr/lib64/sane/libsane-hpgt2500-x86_64.so.1.0.27
    • /usr/lib64/sane/libsane-hpgt2500.so /usr/lib64/sane/libsane-hpgt2500.so.1

    now you only have to make a symbolic link:

    sudo ln -s /usr/lib /usr/lib/i386-linux-gnu

sudo ln -s /usr/lib64 /usr/lib64/x86_64-linux-gnu

    run again hp-setup

    done

  2. I also had the problem where the HP printer installs fine but the scanner plugin does not install (Ubuntu 19).Disabling the plugin.py worked!!! (thank you) but I had to install apparmor-utils first.

    sudo apt install apparmor-utils
sudo aa-disable /usr/share/hplip/plugin.py
hp-plugin

    The last step runs the HP Plugin installer which is needed for printer scanning to work.

  3. I had a slightly different problem. My HP Printer installed fine, but the scanner plugin would not install properly. It seems the trick was to get AppArmor to lower its shields for a Python script.

    Edit: Looking at other answers, it looks like it is common to not have AppArmor utils installed, so you may also need to install it first

    sudo apt install apparmor-utils

sudo aa-disable /usr/share/hplip/plugin.py

    After I did this, the plugin installed correctly.

  4. After following Kai Kramer's answer here I got:

    error: Python gobject/dbus may be not installed
error: Plug-in install failed.

    AND

    cannot access '/var/lib/hp/hplip.state': No such file or directory

    A search on the web got me to try the following and it worked:

    $ aa-disable /usr/share/hplip/plugin.py

Command 'aa-disable' not found, but can be installed with:

sudo apt install apparmor-utils

    Install apparmor utils (mind you I didn't have it installed!!!)

    sudo apt-get install apparmor-utils

    Then run

    sudo aa-disable /usr/share/hplip/plugin.py

    & the run as normal user, not as root:

    hplip-plugin

    Now my printer (laserjet 1020) was installed.
