HPLIP

HPLIP won't install

Asked by Ying Lu

OS: Ubuntu 8.10
Printer: HP M2727nf

In the process of installing HPLIP, it comes to step to download a plugin to enable scanning support. I selected to download from an HP authorized server. But I got an error message saying "ERROR: Plug-in file does not match its digital signature". I did attempted the completed remove the previous HPLIP installation as suggested in web page http://hplipopensource.com/node/188. But I still got the same error.

What could be wrong and how can I workaround?

Command 'hp-check -t' output:

Hp-setup is exactly the program invoked by installation process to download the missing plugin. And it is the program produced the error I mentioned in my original message.

Here's output of running hp-plugin directly.

/Checking for network connection...

I use wget downloaded hplip-3.9.12-plugin.run and attempted to run it. Here's what I got:

$ bash ./hplip-3.9.12-plugin.run

Thanks for your help in advance.

Okay, I ran the hp-setup again pointing to hplip-3.9.12-plugin.run which I downloaded using wget. I was able to install regardless the integrity check failure. Problem solved.
