我正在尝试安装一个插件，该插件似乎是使用 HP 1020 plus 打印机所必需的。运行命令后hp-plugin，我收到一条错误消息。下面发布完整输出：

我正在使用 Ubuntu 21.10。我是新手，对此一无所知。有人可以帮忙吗？非常感谢！
echo $PATH返回/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
并which python3返回/usr/bin/python3
which python并且which python2不返回任何内容。

在聊天过程中我们发现了以下情况。
该问题是由二进制安装的 HPLIP 3.21.10 和 deb 打包的 3.21.6 版本混合引起的。
因此，我们通过 find ~ -name hplip-3.21.10.run - got /home/mathphy226/softwares/hplip-3.21.10.run 找到了 HPLIP 3.21.10 发行版。然后要求它自行删除，如下所示：
cd /home/mathphy226/softwares
sh hplip-3.21.10.run --noexec
cd hplip-3.21.10
sudo hp-uninstall
sudo python3 ./uninstall.py

sudo rm -vrf /usr/local/share/doc/networkx-2.6.3
然后重新启动以重新安装 deb 打包的 HPLIP 3.21.6
sudo apt-get -o Dpkg::Options::="--force-confask" install --reinstall --no-install-recommends --no-install-suggests hplip hplip-data hplip-doc hplip-gui hpijs-ppds libsane-hpaio printer-driver-hpcups printer-driver-hpijs
并手动下载了 HPLIP 插件
cd /home/mathphy226/softwares
wget -c https://developers.hp.com/sites/default/files/hplip-3.21.6-plugin.run
wget -c https://developers.hp.com/sites/default/files/hplip-3.21.6-plugin.run.asc
稍后使用 hp-plugin -i 安装它。
附加说明：根据 HP 官方文档，这款 HP 1020 plus 打印机需要 HPLIP >= 2.7.10，因此不需要二进制 HPLIP。
