Hi, thanks for taking the time to file a bug. Based on that last message from SSH it makes me wonder if the syntax you have is correct.
1) Can you confirm PermitUserEnvironment is set to yes in your sshd_config? 2) Can you provide more details of the line in question in your authorized keys file? For example, if I add: environment="FOO_BAR=1" ssh-rsa AAAAB then connect: root@x:~# env | grep -i foo FOO_BAR=1 This question may also be better suited for the community forums as it is more of a support issue. ** Changed in: openssh (Ubuntu) Status: New => Incomplete ** Changed in: openssh (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to openssh in Ubuntu. https://bugs.launchpad.net/bugs/1771011 Title: Doesn't accept environment variable with underscore in its name in AuthorizedKeysFile Status in openssh package in Ubuntu: Incomplete Bug description: If environment variable name defined in AuthorizedKeysFile contains underscore character (environment="FOO_BAR=1" ...), sshd refuses connection and throws following error: authorized_keys:1: bad key options: invalid environment string To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1771011/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
