Has the key changed to install linuxcnc 2.8?  It worked a month or 2 ago.  I would use the linuxcnc 2.8.2-buster iso, but, I can't get past the "Configure the network" screen on our network in the office.  It tries to configure for DHCPv6, then blanks out and just says "Configure the network.  It appears to break if it can't configure for DHCPv6..  Standard Debian 10.10 install gets past this point and to a screen that says configuring DHCP and goes on to complete the installation.  That would be fine, but, I can't get the keyserver to work to install linuxcnc.

The inuxcnc 2.8.2-buster iso works from my home network.  I really need it to work at the office or be able to install linuxcnc alternatively.  Any ideas?

You sure they updated that page? Last time I tried it they didnt work.
 

It still is not working. I typed:
sudo apt-key adv --keyserver hkp://keys.openpgp.org --recv-key EF1B07FEE0EE663E

and received:
Executing: /tmp/apt-key-gpghome.rr71aIo0kj/gpg.1.sh --keyserver keys.openpgp.org --recv-key EF1B07FEE0EE663E
gpg: key EF1B07FEE0EE663E: new key but contains no user ID - skipped
gpg: Total number processed: 1
gpg: w/o user IDs: 1

Am I missing something?

Hello, this worked for me :sudo apt-key adv --keyserver hkp://pgpkeys.eu --recv-key EF1B07FEE0EE663E

Thanks. keyserver.ubuntu.com worked! I also tried pgpkeys.eu, but, it failed with "NO NAME".
