在 Ubuntu 20.04 上安装 hplip-3.20.5 期间无法安装某些 python 包

  • 772

从 19.10 升级到 20.04 后，我自动删除了许多已弃用的软件包。在 hplip 升级期间，我已确认使用维护者版本的配置文件。但是 Ubuntu 重新启动后，hp 1020 打印机停止打印。每次我刷新它的窗口时，Hplip 工具箱都会挂起。所以我已经完全清除并卸载了 hplip。

使用本指南安装会安装之前安装的 hplip 3.20.3 版本。

所以我从这里为 Ubuntu 下载了 3.20.5 版本，并在x许可的情况下对其进行了修改并运行它：./hplip-3.20.5.run.

它询问我是否要安装缺少的依赖项：

Package-Name         Component            Required/Optional   
pyqt5-dbus           gui_qt5              OPTIONAL            
reportlab            fax                  OPTIONAL            
pyqt5                gui_qt5              REQUIRED            
python-notify        gui_qt5              OPTIONAL

我说y，但是，对于python-pyqt5包裹，我有：

error: Command failed. Re-try #3...
Running 'sudo apt-get install --assume-yes python-pyqt5'
Please wait, this may take several minutes...
error: Package install command failed with error code 100

对于python-dbus.mainloop.pyqt5包裹：

error: Command failed. Re-try #3...
Running 'sudo apt-get install --assume-yes python-dbus.mainloop.pyqt5'
Please wait, this may take several minutes...
error: Package install command failed with error code 100

对于python-notify包裹：

error: Command failed. Re-try #3...
Running 'sudo apt-get install --assume-yes python-notify'
Please wait, this may take several minutes...
error: Package install command failed with error code 100

对于python-reportlab：

error: Command failed. Re-try #3...
Running 'sudo apt-get install --assume-yes python-reportlab'
Please wait, this may take several minutes...
error: Package install command failed with error code 100

我跳过了这些软件包的安装，因为无法安装它们。最后，我得到了下一个错误：

warning: Some HPLIP functionality might not function due to missing package(s).
error: A required dependency 'pyqt5 (PyQt 5- Qt interface for Python (for Qt version 4.x))' is still missing.


RUNNING POST-PACKAGE COMMANDS
-----------------------------
OK


RE-CHECKING DEPENDENCIES
------------------------
error: A required dependency 'pyqt5 (PyQt 5- Qt interface for Python (for Qt version 4.x))' is still missing.
error: Installation cannot continue without this dependency.
error: Please manually install this dependency and re-run this installer.

我也hplip-3.20.5-plugin.run从这里下载

$ bash hplip-3.20.5-plugin.run
Verifying archive integrity... All good.
Uncompressing HPLIP 3.20.5 Plugin Self Extracting Archive..............................................................
Error setting home directory: /etc/hp/hplip.conf not found. Is HPLIP installed?

Universe/Multiverse 存储库已启用，但是：

$ apt-cache search python-pyqt5
python-pyqt5.qwt-doc - Python Qwt6 technical widget library, documentation and examples
$ apt-cache search python-reportlab
python-reportlab-doc - Documentation for the ReportLab Python library (PDF format)
$ apt-cache search python-dbus.mainloop.pyqt5
$ apt-cache search python-notify
python3-notify2 - desktop notifications API for Python 3

软件包python3-pyqt5, python3-reportlab, python3-notify2,python3-dbus.mainloop.pyqt5已安装并且是already the newest versions。

例如，我还可以看到，python-pyqt5包在 19.10 存储库中可用，但是这个包需要qtbase-abi-5-12-4在 eoan 的存储库中不存在的包。18.04 的python-pyqt5包需要不同的 qtbase-abi 包，这在 Bionic 的存储库中不存在。

这是否意味着 phlip-3.20.5 与 20.04 不兼容，或者可能存在一些包含这四个包及其依赖项的附加存储库？

更新：

  • 已安装hplip, hplip-data,hplip-gui包。

  • 从启动器启动 hplip-gui

  • 收到登录信息journalctl -f：

较新的 hplip-3.20.6也不支持 Ubuntu 20.04。

hplip 20.04

  1. Best Answer

    事实上，在 Ubuntu 20.04 上使用 hplip-3.20.6 存在一些问题。安装抱怨pyqt5。我的解决方法是使用自定义选项（而不是自动）安装 hplib-3.20.6。您可以在没有 qt 支持的情况下安装 hplib（没有：图形用户界面 (Qt5)）。请在终端中运行：

    ./hplip-3.20.6.run

    现在您可以选择自定义安装并禁用 qt5：

    Do you wish to enable 'Graphical User Interfaces (Qt5)' (y=yes*, n=no, q=quit) ? n

    你得到：

    INSTALLATION MODE
-----------------
Automatic mode will install the full HPLIP solution with the most common options.
Custom mode allows you to choose installation options to fit specific requirements.

Please choose the installation mode (a=automatic*, c=custom, q=quit) : c


INTRODUCTION
------------
This installer will install HPLIP version 3.20.6 on your computer.
Please close any running package management systems now (YaST, Adept, Synaptic, Up2date, etc).


DISTRO/OS CONFIRMATION
----------------------
Distro appears to be Ubuntu 20.04.

Is "Ubuntu 20.04" your correct distro/OS and version (y=yes*, n=no, q=quit) ? y


DRIVER OPTIONS
--------------
Would you like to install Custom Discrete Drivers or Class Drivers ( 'd'= Discrete Drivers*,'c'= Class Drivers,'q'= Quit)?   : d

Initializing. Please wait...


SELECT HPLIP OPTIONS
--------------------
You can select which HPLIP options to enable. Some options require extra dependencies.

Do you wish to enable 'Network/JetDirect I/O' (y=yes*, n=no, q=quit) ? y
Do you wish to enable 'Graphical User Interfaces (Qt5)' (y=yes*, n=no, q=quit) ? n
Do you wish to enable 'PC Send Fax support' (y=yes*, n=no, q=quit) ? y
Do you wish to enable 'Scanning support' (y=yes*, n=no, q=quit) ? y
Do you wish to enable 'HPLIP documentation (HTML)' (y=yes*, n=no, q=quit) ? y

    我希望这个评论会有用，问候。

  2. 有一个解决方案，它需要一段时间。我刚刚用 Qt5 编译了 hplip 3.20.9。并使用下面的讨论提示来解决 python-PyQt5 缺少的依赖项：https ://answers.launchpad.net/hplip/+question/691141 现在打印机似乎开始使用 Ubuntu 20.04。

        HP Linux Imaging and Printing System (ver. 3.20.9)

Note: hp-check can be run in three modes:
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).

  3. 尝试使用 pip 安装 pyqt5：

    sudo apt install python-pip
pip install pyqt5
pip install pyqt5.sip

    或者如果您的 hplip 版本需要 python3：

    sudo apt install python3-pip
pip3 install pyqt5
pip3 install pyqt5.sip

  4. 即使使用 . 仍然是一个问题<=hplip-3.21.10。

    它会尝试安装python2软件包，即使您的 20.04 Ubuntu 已python3默认安装。

    要修复安装此帮助程序包：

    sudo apt install python-is-python3

    它会假装hplip安装程序使用python3而不是python2.

  5. 总结以前提到的解决方案（来自 Bartosz），对我有用的是基本上将python符号链接更改/usr/bin为指向 Python 3 而不是 Python 2，如https://answers.launchpad.net的答案之一所述/hplip/+问题/691141。

    cd /usr/bin
sudo unlink python
sudo ln -s /usr/bin/python3 python
    • 2

  6. 我遇到过这个问题，也很难找到解决方案，因为这个问题似乎我还没有安装pyqt5，但它已经安装（使用 python3）从这个 gist借来

    pip3 install --user pyqt5  
sudo apt-get install python3-pyqt5  
sudo apt-get install pyqt5-dev-tools
sudo apt-get install qttools5-dev-tools

    最后，我找到了一个描述ubuntu 上的HPLIP问题的网站，就像我在这里https://ubuntuhandbook.org/index.php/2021/07/install-latest-hplip-ubuntu-20-04-fix/

    问题是因为默认情况下HPLIP安装程序使用 python at/usr/bin/python并且指的是与我python2.7的安装无关pyqt5python3

    因此，基于该站点，我选择update-alternatives在安装程序使用时将 python 版本切换为 python3/usr/bin/python

    sudo update-alternatives --install /usr/bin/python python /usr/bin/python2 1
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 2

    第一个命令是在选项号 1 处添加 python2，第二个命令是在选项号 2 处添加 python3。

    这是我切换到python3和python2时的屏幕截图，然后再次使用python3作为默认安装开始安装

    示例切换 python 版本

  7. hplip 3.20.5 及以下 hplip 版本似乎不支持 Ubuntu 20.04。至少 Ubuntu 20.04 并没有在hp 的开发者门户中提及 | 发行说明页面。最后提到的 Ubuntu 版本当时是 19.10。

    因此，就我而言，最佳解决方案是等待更新的 hplip 版本并在 VirtualBox 上使用 18.04 VM，并为我的 hp 1020 打印机启用 USB 1.1 直通，直到发布更新的 hplip。

  8. 我不知道怎么做，但也许 3.20.3 的一些更新已经解决了 20.04 打印的问题

    $ cat /var/log/dpkg.log | grep hplip

2020-08-07 15:29:39 status config-files hplip:amd64 3.20.3+dfsg0-2

    连接打印机后出现对话窗口，说需要插件，并提出了一些选项。我保留了默认并安装了建议的插件。安装后，我可以使用来自 Ubuntu 20.04 的 HP LJ 1020 进行打印

    $ dpkg --list | grep hplip
ii  hplip             3.20.3+dfsg0-2      amd64     HP Linux Printing and Imaging System (HPLIP)

ii  hplip-gui         3.20.3+dfsg0-2      all       HP Linux Printing and Imaging - GUI utilities (Qt-based)

    尽管有hp-check输出，它仍然有效：

    Missing Required Dependencies
-----------------------------
error: 'libcups2' package is missing/incompatible 
error: 'python3-pyqt4' package is missing/incompatible 
error: 'gtk2-engines-pixbuf' package is missing/incompatible 

Missing Optional Dependencies
-----------------------------
error: 'python3-dbus.mainloop.qt' package is missing/incompatible 

Total Errors: 3

    安装了第 1 和第 3 包，因此它们不兼容，第 2 和第 4 包在官方 Ubuntu 存储库中不可用。它可能会影响某些功能。但我很高兴它至少能打印出来。

  9. 由于截至 2021 年 2 月 15 日提供的解决方案均未针对我的特定情况解决此问题（即 64 位 XUbuntu 20.04.3 LTS，内核为 5.13.0-28-generic + 无线 HP Deskjet Ink Advantage 2546 aka “Deskjet 2540 series”一体机打印机），我最终运行了以下shell终端命令，然后为我解决了这个问题：

    1. 清除当前的 HPLIP 安装：

      sudo apt-get purge hplip* -y

    2. 安装一个 DEB 包，使任何应用程序级对python的引用指向系统默认（即 *Ubuntu 20.04 的默认）python 3安装：

      sudo apt install python-is-python3 -y

    3. 安装 *Ubuntu（即 Ubuntu、KUbuntu、XUbuntu...）20.04 附带的 HPLIP 软件包：

      sudo apt install hplip hplip-data hplip-gui -y

    4. 访问当前用户的下载文件夹：

      cd ~/Downloads

    5. 下载 HPLIP 版本 3.21.12（2021-12-16 发布）作为.run（即 shell 脚本）安装文件并将其存储在此类用户的下载文件夹中：

      wget https://sourceforge.net/projects/hplip/files/hplip/3.21.12/hplip-3.21.12.run/download -O ./hplip-3.21.12.run

    6. 使下载的脚本可执行：

      chmod +x ./hplip-3.21.12.run

    7. 运行安装脚本：

      ./hplip-3.21.12.run

    8. 在安装过程中，按Enter( return) 以应用所有默认 ( *) 选项。如果系统询问您是否要删除（卸载）当前的 HPLIP 安装，然后从脚本中安装 HPLIP，请选择此类选项 ( i) 而不是退出选项。

    9. 确认您要下载并安装 HPLIP 插件（或者re-plug in如果该插件已安装）。请耐心等待：下载和安装插件需要一段时间。您可能认为插件安装程序的窗口是静态的，因为什么都没有发生，但查看终端窗口可以明显看出安装程序正在联系 Web 服务器，下载然后安装插件。

    10. r重新启动/重新启动计算机（一旦安装程序询问您是否要重新启动，您可以按下并确认，或者您也可以完成安装，关闭所有窗口，然后手动重新启动）。

    打开 HP 打印机后，如果单击面板上的插件并单击HP 设备管理器后没有任何反应，请单击应用程序菜单，键入hp 设备管理器并选择它，以便添加并配置您的惠普打印机。您也可以通过发出以下命令从终端运行HP 设备管理器：

    hp-toolbox & exit
