Public bug reported: When I start a standard Ubuntu 11.10 Oneiric instance (ami-a7f539ce) on Amazon EC2 I can ssh in just fine with the default .ssh/authorized_keys file.
If I prefix the ssh key in .authorized_keys with the option "no-pty " then attempts to ssh fail with the error: PTY allocation request failed on channel 0 This worked fine on previous versions of Ubuntu but the behavior seems to have changed in Oneiric. This failure means that the gitolite package is not working on Ubuntu 11.10 Oneiric as it uses no-pty in the ssh authorized_keys file. Here's a sample of the $HOME/.ssh/authorized_keys file that fails: no-pty ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA6rn8cl41CkzaH4ZBhczOJZaR4xBBDI1Kelc2ivzVvCBTHcdJRWpDd5I5hY5W9qke9Tm4fH3KaUVndlcP0ORGvS3PAL4lTpkS4D4goMEFrwMO8BG0NoE8sf2U/7gaUkdcrDC7jzKYdwleRCI3uibNXiSdeG6RotClAAp7pMflDVp5WjjECDZ+8Jzs2wasdTwQYPhiWSiNcfbfS97QdtROf0AcoPWElZAgmabaDFBlvvzcqxQRjNp/zbpkFHZBSKp+Sm4+WsRuLu6TDe9lb2Ps0xvBp1FTHlJRUVKP2yeZbVioKnOsXcjLfoJ9TEL7EMnPYinBMIE3kAYw3FzZZFeX3Q== ProblemType: Bug DistroRelease: Ubuntu 11.10 Package: ssh (not installed) ProcVersionSignature: User Name 3.0.0-12.20-virtual 3.0.4 Uname: Linux 3.0.0-12-virtual i686 ApportVersion: 1.23-0ubuntu3 Architecture: i386 Date: Mon Oct 17 02:54:57 2011 Ec2AMI: ami-a7f539ce Ec2AMIManifest: (unknown) Ec2AvailabilityZone: us-east-1d Ec2InstanceType: m1.small Ec2Kernel: aki-805ea7e9 Ec2Ramdisk: unavailable ProcEnviron: LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: openssh UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: openssh (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug ec2-images i386 oneiric ** Summary changed: - ec2 oneiric ssh "no-pty" triggers "PTY allocation request failed on channel 0" + EC2 Oneiric ssh "no-pty" triggers "PTY allocation request failed on channel 0" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/876168 Title: EC2 Oneiric ssh "no-pty" triggers "PTY allocation request failed on channel 0" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/876168/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
