我正在使用 Ubuntu 18.04 和打印机 HP Color Laserjet pro mfp m281fdw。可以打印，但不能扫描。
为了修复缺失的扫描功能，我想我会更新我的 HPLIP 并安装最新的 hplip-3.20.9.run。
我使用的文件来自https://developers.hp.com/hp-linux-imaging-and-printing并按照自动安装的说明进行操作。
不幸的是，安装没有完成。几个小时后它才开始......

只是不断旋转。没有错误信息。...
更新 我停止了未结束的安装过程。并且
hp-check -r
dpkg -l | egrep HP
所以我发现我确实有不同 hplip 版本的分数……
我做到了
sudo apt purge hplip hplip-data
在重新安装新版本之前删除 hplip。（我希望这样没问题。）此命令的结果如下：
sudo apt purge hplip hplip-data

我记得未完成的 jitsi 安装导致了其他安装出现安装问题。
我想在运行 hplip-3.20.9.run 之前，我应该清理配置中未完成的 jitsi 剩余部分。我该如何清理它们？
