需要pyqt4
需要pyqt4
提问于 2020-05-01 03:05:19
我已经升级了我的系统从19.10到20.04，一切正常工作，除了我不能加载hp-系统或任何其他部分的程序。
我遇到的问题是pyqt4在20.04可用，我一直无法找到它。
终端错误如下：

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).
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]

您可能需要完全重新安装HP打印机支持，因为您删除了所有涉及HPLIP的内容。您可能需要访问HPLIP页面并下载并安装最新的HPLIP。如果您能够这样做，它将设置您的打印机，然后给您机会安装正确的插件，将使您的打印机的所有功能。
如果您在执行其他操作之前运行了N0rbert提供的命令，那么您可能已经避免了这么多麻烦：
sudo apt install hplip-gui(我知道，你当时不知道，我也是很难学到的。这是因为HPLIP已经安装在Ubuntu上，而不是GUI上，您需要GUI才能获得插件。)
然后运行“”(我从Dash运行它，但您也可以从命令行运行它)。这将打开一个GUI，这将使您有机会安装所需的插件。许多惠普打印机需要安装这个插件才能执行某些功能(例如扫描和传真)。
每次我安装新版本的Ubuntu (或重新安装)时，我都必须这样做，因为我的HP打印机是需要插件的打印机之一，而您的打印机似乎也需要插件。默认情况下没有加载插件，不幸的是，在任何地方都没有提供有关如何解决问题的信息。

HPLIP支持3.16.5及以上版本的Qt5
启用qt5支持
You need to install the following dependencies
PyQt5
python-qt5-dbus
Go to source of hplip. By default its in ~/Downloads.
Run the following commands
./configure --prefix=/usr --enable-qt5 --disable-qt4
make
"make install" as root userAsk Ubuntu用户

从20.04回购系统安装的版本似乎有问题，因为在20.04升级之前我在计算机上安装了3.20.3，我从ubuntu20.10存储库安装了3.20.5。现在，除了设备管理器之外，一切似乎都正常。当我为设备管理器点击hp系统时，它永远不会加载设备管理器。对于hp-systray有一个gnome扩展，我可以从那里调用设备管理器。所以不能完美地工作，但它是有效的。这是alt应用程序的链接。https://extensions.gnome.org/extension/1339/hplip-menu/
