我在 HP ProBook 440 G3 上使用 ubuntu 16.04。它有一个指纹读取器。lsusb显示以下驱动程序
Bus 001 Device 004: ID 138a:003f Validity Sensors, Inc. VFS495 Fingerprint Reader
但是Fingerprint GUIorFprint显示 no driver ，正如预期的那样，因为138a:003f不在他们支持的列表中。那么如何在 ubuntu 中使用指纹读取器呢？
因此，我安装了鱿鱼，并在删除鱿鱼时意外删除了 /etc/squid/ 文件夹。现在我无法再次安装squid。我现在如何安装鱿鱼。的输出apt-get install squid
