我正在尝试通过 Toshiba Chromebook 上的 crouton 连接 HP Deskjet 3000。我按照以下说明进行安装http://hplipopensource.com/hplip-web/install/install/index.html我最终遇到了这个问题：
DEPENDENCY AND CONFLICT RESOLUTION
----------------------------------
Running 'sudo apt-get install --assume-yes libcups2'
Please wait, this may take several minutes...
error: A required dependency 'cups (CUPS - Common Unix Printing System)' is still missing.
RUNNING POST-PACKAGE COMMANDS
-----------------------------
OK
RE-CHECKING DEPENDENCIES
------------------------
error: A required dependency 'cups (CUPS - Common Unix Printing System)' is still missing.
error: Installation cannot continue without this dependency.
error: Please manually install this dependency and re-run this installer.
但是当我跑步时：
sudo apt-get install cups
我得到：
Reading package lists... Done
Building dependency tree
Reading state information... Done
cups is already the newest version.
The following package was automatically installed and is no longer required:
libglade2-0
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
(precise)alan@localhost:~$
我现在有点迷茫了。如何安装 CUPS 以便 hplip 能够识别它并完成安装？
答案1
要启动服务，请执行：
sudo /etc/init.d/cups start
它对我有用
答案2
我遇到了同样的问题，并且仅通过运行 Cups 服务就解决了它：
service cups start
看起来 HP 安装脚本实际上正在检查服务是否已启动，以推断包是否已安装。
答案3
16.04 + systemd
sudo systemctl start cups
sudo systemctl start cups-browsed
