Installed Mageia 8. Had to do a complete install as trying to just upgrade failed due to nvidia clashes. Installed hplip for my combined printer-scanner but it requires the driver plugin to scan. Keeps failing as it says checksum error. Anybody any ideas?
Thanks.

I had that same problem on Mageia 8. To get the plugin installed, I had to run “hp-plugin”. I ran that as root, and it complained that I should not run it as root.

So I hung up on it, logged out of root, and ran it as a regular user. When I did that, it posted a GUI instead of the CLI interface.

In the dialog, select the checkbox for "Download and install the plug-in from an HP authorized server (recommended)"

It threw the usual error about the plugin keys. I said to download and install anyway.

After it downloads the plugin, it demands the root password anyway…. after warning that it should not be run as root. Go figure. I guess they are pushing the use of the GUI tool. I don’t know.

After supplying the root password, hp-plugin declares success, and the printer works.

Try running hp-plugin

Many thanks. I will try later and see how I get on.

Here is the GUI dialog box that hp-plugin posted when I ran it as a regular user.

No chance given to carry on with installation as it just exited. Don't know where to download the plugin from the websit.

Did you install the printer from the MCC? I have had issues with that in the past when the printer required the plugin. The MCC would install the printer, but then the printer would not work. I had to install the printer from the command line using hp-setup. In past version of the OS that would automatically download and install the plugin, but it didn't do that on Mageia 8, so I ran hp-plugin to install the plugin.

You could try uninstalling the printer and then re-installing it from the command line using hp-setup. Here is how I have done it.

Make sure the internet is live.
Make sure the printer is on, connected to the wifi and not asleep.
Connectivity can be confirmed and printer awakened by pinging it.
Log in as root
# hp-setup -i 192.168.1.252 – must give the IP of the printer or the printer will not be found
Answer all the questions. The defaults work OK. Go ahead and give it a location.

The -i switch causes hp-setup to run in “interactive” mode, which means purely text based. If run as root using the -i switch, it might work.

Then, if hp-setup didn't install the plugin try hp-plugin again.

Don't know where to download the plugin from the websit.

I have no idea how to download the plugin from the website. I have always installed it using the hp tools, which download the plugin and install it.

Tried everything you suggested, still no luck.

Exactly where is it failing? Crashing? Seems to install but then doesn't work? Which program doesn't work?

What are the error messages?

I have an hp printer/scanner. It prints fine but scanning needs the plugin. Worked fine on Mageia 7.1 but not on 8. When I attempt using GUI or konsole, checksum error, can't continue with installation, won't let me.

Thanks.

Please run either hp-setup or hp-plugin in debug mode from a terminal as root, go through the normal installation process, and post the whole output here. So either

Code: Select all

hp-setup -i -g

or

Code: Select all

hp-plugin -i -g

FWIW, the plugin can also be downloaded directly from https://developers.hp.com/hp-linux-imag ... ng/plugins or https://www.openprinting.org/download/p ... P/plugins/
https://developers.hp.com/hp-linux-imag ... lugin.html has information which driver requires what min. plugin version.
Which is exactly what hp-plugin is intented to do automatically.

error: /home/paul/.hplip/hplip-3.20.11-plugin.run file does not match its checksum. File may have been corrupted or altered

The output was to big to copy but the above line is the result hp-plugin -i -g.

I hope this helps.

Thanks

FWIW, you should be able to manually download and install https://developers.hp.com/sites/default ... plugin.run
After that is install, you can run hp-setup -i

Hi Doctor5000,
It seems to be a script. How would you download it and where would you put it?
Thanks.

You can download it via your brower or in terminal with wget or curl or whatever you prefer. It does not matter where you put it, you just need to install it via hp-plugin afterwards.

Code: Select all

cd ~/Downloads
wget https://developers.hp.com/sites/default/files/hplip-3.20.11-plugin.run
hp-plugin -i -p .

You can also install it manually:

Code: Select all

chmod +x hplip-3.20.11-plugin.run
./hplip-3.20.11-plugin.run

It worked!!!
Many thanks
