This gpg-key wouldn’t even import.

Went to https://pgp.mit.edu and found https://pgp.mit.edu/pks/lookup?op=get&search=0xE913CD692884ECEF copied as RPM-GPG-KEY-katello
Was then able to import key: rpm --import RPM-GPG-KEY-katello
and verify that rpm matched the key from mit. New file is 993 bytes in size with output:

[root@ap00 rpm-gpg]# cat RPM-GPG-KEY-katello

Expected outcome: katello-client-repos rpms should include correct gpg key out-of-the-box.

Other relevant data:
Until now I’ve been having to disable gpg-checking on katello server and in client join scripts.

Can somebody post the actual key ID 4d0d8597? I tried searching for it with no joy.
