我一直收到这个错误；
xsane: symbol lookup error: /usr/lib/x86_64-linux-gnu/libsane.so.1: undefined symbol: libusb_set_option
和这个错误；
checking for sane_open in -lsane... no
configure: error: cannot find sane-backends-devel support (or --disable-scan-build)"
when trying to install hplip-3.20.5
我从 Ubuntu 19 开始就遇到了这个问题，我现在正在使用 Ubuntu 20.04。我已经重新安装了libusb-1，libsane.so.1
我正在尝试安装 HP 多功能打印机“HP Office jet pro 9018”
首先，以下是 tl;dr --

当我尝试运行 xsane 时出现此问题；
xsane: symbol lookup error: /usr/lib/x86_64-linux-gnu/libsane.so.1: undefined symbol: libusb_set_option
答案1
看起来你使用 PPA 弄乱了一些东西。使用以下命令删除它：
sudo apt-get install ppa-purge
sudo ppa-purge ppa:rolfbensch/sane-git
然后通过以下方式从官方存储库重新安装 sane：
sudo apt-get install --reinstall libsane1=1.0.29-0ubuntu5 libsane-common=1.0.29-0ubuntu5
关于 HPLIP，请考虑通过运行以下命令从存储库安装它：
sudo apt-get install hplip-gui
随后hp-setup是
hp-plugin
因为您可能需要它来支持您设备的扫描仪。
答案2
按照 #1 的指示操作后，存储库 hplip 不起作用，并收到与 libusb、libsane 等相关的错误。我尝试重新安装，但无济于事。查看 /usr/local/lib/ 我发现；
-rw-r--r-- 1 root root 574248 Apr 3 2015 libusb-1.0.a
-rwxr-xr-x 1 root root 954 Apr 3 2015 libusb-1.0.la
lrwxrwxrwx 1 root root 19 Apr 3 2015 libusb-1.0.so -> libusb-1.0.so.0.1.0
lrwxrwxrwx 1 root root 19 Apr 3 2015 libusb-1.0.so.0 -> libusb-1.0.so.0.1.0
-rwxr-xr-x 1 root root 334416 Apr 3 2015 libusb-1.0.so.0.1.0
注意日期。我删除了 libusb-1.0.so.0.1.0 并通过以下方式重新安装
sudo apt-get install --reinstall libusb-1.0.0
sane 开始工作，但存储库“hplip”抱怨找不到 models.dat 文件。我安装了 HP 的 hplip-3.20.6，现在我有打印机和扫描仪
解决了
