Unable to check digital key for hp-plugin

Asked by Andrey Cherepanov

$ rpm -qf /usr/bin/hp-plugin hplip-3.19.3-alt1.x86_64

Ourput: Receiving digital keys: /usr/bin/gpg --homedir /home/user/.hplip/.gnupg --no-permission-warning --keyserver pgp.mit.edu --recv-keys 0x4ABA2F66DBD5A95894910E0673D770CDA59047B9

Please, put correct keys to key server.

Also there is advise on page https://developers.hp.com/hp-linux-imaging-and-printing/hplipDigitalCertificate.html :

  For HPLIP Version 3.9.12 and above:
  /usr/bin/gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9

I got:
$ LC_ALL=C /usr/bin/gpg --keyserver pgp.mit.edu --recv-keys 0xA59047B9
gpg: requesting key A59047B9 from hkp server pgp.mit.edu
gpgkeys: key A59047B9 can't be retrieved
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0
gpg: keyserver communications error: keyserver helper general error
gpg: keyserver communications error: unknown pubkey algorithm
gpg: keyserver receive failed: unknown pubkey algorithm

What is wrong with public keys?

"gpg: keyserver communications error"
It seems that there are some problems with the MIT PGP server.

I suggest that you try again and/or try with a different key server, e.g.

LC_ALL=C /usr/bin/gpg --keyserver keyserver.ubuntu.com --recv-keys 0xA59047B9

Does this give similar error messages?

It's OK. Let's patch hplip do not use MIT PGP server?
What do you use in Ubuntu?
