Thanks a lot! 0644 are really the important bits, so while the behavior is still "user-surprising" it shouldn't cause any practical problems for us.

This causes problems particularly when used on the global known hosts file (/etc/ssh/ssh_known_hosts), because then only root can read it. Programs running non-interactively as non- root users suddenly fail to SSH and it's not immediately obvious why. To reproduce: $ ssh-keyscan github.com >test_known_hosts $ chmod 741 test_known_hosts $ ssh-keygen -R github.com -f test_known_hosts $ stat test_known_hosts ... Access: (0600/-rw-------) ... Expected behavior: file permissions remain unchanged (mode 0741 in this example). $ lsb_release -rd Description: Ubuntu 18.04.6 LTS Release: 18.04 $ apt-cache policy openssh-client openssh-client: Installed: 1:7.6p1-4ubuntu0.6 To manage notifications about this bug go to: https://bugs.launchpad.net/openssh/+bug/1966591/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
