I found a post here
https://bugs.launchpad.net/hplip/+bug/1818629

to get around the gpg error do this.....you can not use sudo ....needs full root

Code: Select all

sudo su
echo '162.213.33.8 pgp.mit.edu' >> /etc/hosts
hp-setup -i

should now work.

(2) if it does not run the below command with as a local user and also with sudo at beginning
hp-setup -i needs root powers

# below as local user is key import success compared to older post

Code: Select all

gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9

It is a HP LaserJet Pro MFP m225dn

After running hp-setup-i, it seemed to work fine, setting up the printer, but it didn't install the plugin, and still did not work with the scanner.

I then tried (2), and now I get a different error when running hp-setup

Code: Select all

$ gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9
gpg: directory '/home/david/.gnupg' created
gpg: keybox '/home/david/.gnupg/pubring.kbx' created

EDIT
my bad. Even tho you did not disable python script extra line to be sure.

1)

Code: Select all

sudo su
gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9
/usr/bin/aa-enabled /usr/share/hplip/plugin.py
# stay as root
hp-setup -i

2) as local user

Code: Select all

sudo hp-plugin

allegedly as we have imported gpg key as local and root user, it should work in theory. but I am getting tired and so to bed

[davidwillis]

my bad....we need to re-enable the python script first me thinks

Code: Select all

sudo su
/usr/bin/aa-enabled /usr/share/hplip/plugin.py
# stay as root
hp-setup -i

Code: Select all

# /usr/bin/aa-enabled /usr/share/hplip/plugin.py
unknown option '/usr/share/hplip/plugin.py'
/usr/bin/aa-enabled: [options]
  options:
  -q | --quiet        Don't print out any messages
  -h | --help         Print help

[gor9]

sorry I have editted above post good luck

edit ignore the re-enable command pls

[davidwillis]

Still no luck.... But I just thought of something. my wifi/bluetooth did not work, so I installed kernel 5.18. Do you think that could have anything to do with this problem?

So I got it working.
I just went to https://developers.hp.com/hp-linux-imag ... ng/plugins
Downloeded the plugin hplip-3.21.4-plugin.run
as root # hp-setup
Choose select path to the plugin (advanced)
put the path to where I downloaded it

And it installed and is now working!
