Comment 38 for bug 1818629

A printer from 2007, as HP Laserjet P1006. Working previously, I try to install today with the same error result about pgp.mit.edu and the keys.

I am user of Ubuntu since 2005. It seems really not understable how a simply bug of keys affecting so many people get reported from more than 2 years and nobody takes a minute to fix in official repositories or main company as HP.

Another quick solution, is replace the host for the ubuntu keyring server and use as alias for pgp.mit.edu:

sudo echo '162.213.33.8 pgp.mit.edu' >> /etc/hosts

Which if you see the ping, it is being used for crypto mining, and redirecting to:

pgp.mit.edu -> cryptonomicon.mit.edu (18.9.60.141)
