hplip不使用新的Ubuntu 20.04安装

Question

我刚刚完成了Ubuntu20.04.1在联想瑜伽730上的干净安装。我有一个无线的HP Photosmart C4780，我已经成功地安装在另一台Ubuntu20.04和Ubuntu18.04机器上，只需使用

hp-setup 192.168.0.22

当我第一次登录到新安装时，我使用

apt list --installed

告诉我已经安装了hplip和hplip数据。我跑了

apt install hplip-gui

然后试着

hp-setup 192.168.0.22

因为错误而失败

error:  Printer queue setup failed.   Error : successful-ok-ignored-or-substituted-attributes

为了检查出了什么问题我跑了

hp-doctor

第一件事看起来很奇怪，那就是报道说，Ubuntu20.04上的hplip是针对qt5 5编译的.。此外，许多报告丢失/不兼容的软件包已经安装(通过apt)。

在重新安装之前，我尝试过apt purge处理掉所有的hplip并重新安装它们，但始终没有成功。我尝试了几次，最终以某种方式破坏了我的系统，导致了新的安装。

我不知道从这里该怎么做才能让hplip工作。

Answer 1

从hplip的发射台网站上，我找到了一个对我有用的解决方案。它是这条线中的post #7。我在问题中描述的问题是由于Ubuntu20.04使用python3而减少了对python2的支持。如果/usr/bin/python链接到python 2版本，那么运行hplip-3.20.**..run将遇到报告的问题，试图安装必要的python组件但失败。

若要诊断此问题，请运行

python --version

如果您得到一个带有前导数字2的版本，则修复如下

sudo unlink /usr/bin/python
sudo ln -s /usr/bin/python3.* /usr/bin/python

其中python3.*是您安装的python3的任何版本。你可以通过运行

ls /usr/bin/python*

一旦我做了这个，然后跑

sh hplip-3.20.**.run

工作得很好

Answer 2

试试这个：

将文件下载到~/Dowload

https://sourceforge.net/projects/hplip/files/hplip/3.20.6/hplip-3.20.6.run/download?use_mirror=nchc

打开终端并删除先前安装的版本：

sudo apt remove hplip*

光盘到下载安装程序的位置。

cd ~/Downloads

要安装此命令，请运行以下命令：

sh hplip-3.20.6.run

选择安装模式自动，输入一个

确保安装程序检测到正确的Linux发行版。

输入根用户/超级用户密码。

安装程序现在将检测系统在安装HPLIP之前需要安装哪些依赖项。

如果您的系统缺少任何依赖项，则现在下载并安装它们。

./configure为安装准备HPLIP，并验证您的系统具有HPLIP所需的所有依赖项。

然后执行“‘make”。为您的系统编译("builds") HPLIP。

“”是实际的安装过程，这个步骤是HPLIP实际安装到您的系统的地方。

使用‘hp-设置’配置您的打印机。

第一步是选择打印机连接类型。

接下来，安装工具将显示检测到的打印机。

选择要用于打印机的PPD文件，通常需要选择推荐的PPD文件。

单击"AddPrinter“完成打印机安装过程。

Answer 3

您必须安装python3和所有工具包。

sudo apt install python3-pip
sudo apt-get install --assume-yes python3-pyqt5
sudo apt-get install --assume-yes python3-dbus.mainloop.pyqt5
sudo apt-get install --assume-yes python3-notify

然后，当您运行hplip时，对旧python的失败安装响应"no“。

sh hplip-3.20.9.run

最后：

sudo apt-get install libcanberra-gtk-module

这似乎是必要的，尽管我不知道为什么。删除您的打印机，然后重新安装，它应该可以工作。
